Qur'ān 49:12Arabic sense: الظن, تجسسوا
يَٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُواْ ٱجۡتَنِبُواْ كَثِيرࣰ ا مِّنَ ٱلظَّنِّ إِنَّ بَعۡضَ ٱلظَّنِّ إِثۡمࣱۖ وَلَا تَجَسَّسُواْ وَلَا يَغۡتَب بَّعۡضُكُم بَعۡضًاۚ أَيُحِبُّ أَحَدُكُمۡ أَن يَأۡكُلَ لَحۡمَ أَخِيهِ مَيۡتࣰ ا فَكَرِهۡتُمُوهُۚ وَٱتَّقُواْ ٱللَّهَۚ إِنَّ ٱللَّهَ تَوَّابࣱ رَّحِيمࣱ
Believers, avoid making too many assumptions- some assumptions are sinful- and do not spy on one another or speak ill of people behind their backs: would any of you like to eat the flesh of your dead brother? No, you would hate it. So be mindful of God: God is ever relenting, most merciful

You will not be blamed whether you give a hint that you wish to marry these women, or keep it to yourselves- God knows that you intend to propose to them. Do not make a secret arrangement with them; speak to them honourably and do not confirm the marriage tie until the prescribed period reaches its end. Remember that God knows what is in your souls, so be mindful of Him. Remember that God is most forgiving and forbearing

After sorrow, He caused calm to descend upon you, a sleep that overtook some of you. Another group, caring only for themselves, entertained false thoughts about God, thoughts more appropriate to pagan ignorance, and said, ‘Do we get a say in any of this?’ [Prophet], tell them, ‘Everything to do with this affair is in God’s hands.’ They conceal in their hearts things they will not reveal to you. They say, ‘If we had had our say in this, none of us would have been killed here.’ Tell them, ‘Even if you had resolved to stay at home, those who were destined to be killed would still have gone out to meet their deaths.’ God did this in order to test everything within you and in order to prove what is in your hearts.

O you who believe! Avoid much suspicion; indeed some suspicion is sin. And spy not, neither backbite one another. Would one of you like to eat the flesh of his dead brother? You would hate it. And have Taqwa of Allah. Verily, Allah is the One Who forgives and accepts repentance, Most Merciful (12)
The Prohibition of Unfounded Suspicion
Allah the Exalted forbids His faithful servants from being suspicious, which includes having doubts and suspicions about the conduct of one's family, relatives and other people in general. Therefore, Muslims are to avoid suspicion without foundation. The Leader of the faithful 'Umar bin Al-Khattab said, "Never think ill of the word that comes out of your believing brother's mouth, as long as you can find a good excuse for it."
Malik recorded that Abu Hurayrah, may Allah be pleased with him, said that Allah's Messenger ﷺ said,

Ha! There you are: You love them, but they do not love you. The faithful had limpid hearts and generous natures, and they did not keep tenderness and mercy back from the estranged. They wanted good for them and attached their hearts to their submission. They wanted their salvation and did not hold back God's mercy from them-whether they were acquaintances or strangers. This kept on crossing their minds: Bring the sweetmeat, for it is the heart's beloved, suited for both the elect and the common. This is the same tenderness that MuḤammad showed to the estranged. He said, “O God, guide my people, for they do not know.” As for the unbelievers, those who had no limpidness in their hearts or loyalty in their natures, they never wanted good for the people of faith, nor did they love them. They grieved at the good that reached them and became happy at the bad. God says, “If something beautiful

1851 to 1875 of 2,381Unattended emotional faces elicit early lateralized amygdala-frontal and fusiform activations.
Human adaptive behaviour to potential threats involves specialized brain responses allowing rapid and reflexive processing of the sensory input and a more directed processing for later evaluation of the nature of the threat. The amygdalae are known to play a key role in emotion processing. It is suggested that the amygdalae process threat-related information through a fast subcortical route and slower cortical feedback. Evidence from human data supporting this hypothesis is lacking. The present study investigated event-related neural responses during processing of facial emotions in the unattended hemifield using magnetoencephalography (MEG) and found activations of the amygdala and anterior cingulate cortex to fear as early as 100 ms. The right amygdala exhibited temporally dissociated activations to input from different visual fields, suggesting early subcortical versus later cortical …

Early adversity, for example poor caregiving, can have profound effects on emotional development. Orphanage rearing, even in the best circumstances, lies outside of the bounds of a species-typical caregiving environment. The long-term effects of this early adversity on the neurobiological development associated with socio-emotional behaviors are not well understood. Seventy-eight children, who include those who have experienced orphanage care and a comparison group, were assessed. Magnetic resonance imaging (MRI) was used to measure volumes of whole brain and limbic structures (e.g. amygdala, hippocampus). Emotion regulation was assessed with an emotional go-nogo paradigm, and anxiety and internalizing behaviors were assessed using the Screen for Child Anxiety Related Emotional Disorders, the Child Behavior Checklist, and a structured clinical interview.

Exaggerated and disconnected insular-amygdalar blood oxygenation level-dependent response to threat-related emotional faces in women with intimate-partner violence posttraumatic stress disorder.
Background: Intimate-partner violence (IPV) is one of the most common causes of posttraumatic stress disorder (PTSD) among women. PTSD neuroimaging studies have identified functional differences in the amygdala and anterior cingulate cortex (ACC)/medial prefrontal cortex during emotion processing. Recent investigations of the limbic sensory system and its associated neural substrate, the insular cortex, have demonstrated its importance for emotional awareness. This study examined the hypothesis that women with IPV-PTSD show a dysregulation of this limbic sensory system while processing threat-related emotional faces.
Methods: 12 women with IPV-PTSD and 12 nontraumatized comparison women underwent blood oxygenation level-dependent functional magnetic resonance imaging while completing an emotional face-matching task.
Results: IPV-PTSD subjects relative to comparison subjects displayed inc…

Short- and long-term consequences of different early environmental conditions on central immunoreactive oxytocin and arginine vasopressin levels in male rats.
Numerous studies have provided evidence for an important role for the neuropeptides oxytocin (OT) and arginine vasopressin (AVP) in establishment of social behaviour early in life, such as mother-pup interactions. However, there are few reports examining the consequences of early-life experiences on OT and AVP in male offspring. We have used the maternal separation (MS) model to study the effect of different early environmental conditions in rats. The purpose was to study OT and AVP in rats subjected to prolonged daily MS (360 min, MS360), short daily MS (15 min, MS15) and conventional animal facility rearing (AFR) during postnatal days 1-21. In addition, the influence of the presence or absence of littermates during MS, i.e. litter-wise (l) or individual (i) MS, was assessed. The immunoreactive (ir) peptide levels were measured in the hypothalamus, amygdala and pituitary gland of 3 and …

Abnormally reduced dorsomedial prefrontal cortical activity and effective connectivity with amygdala in response to negative emotional faces in postpartum depression.
Objective: Postpartum major depression is a significant public health problem that strikes 15% of new mothers and confers adverse consequences for mothers, children, and families. The neural mechanisms involved in postpartum depression remain unknown, but brain processing of affective stimuli appears to be involved in other affective disorders. The authors examined activity in response to negative emotional faces in the dorsomedial pre-frontal cortex and amygdala, key emotion regulatory neural regions of importance to both mothering and depression.
Method: Postpartum healthy mothers (N=16) and unmedicated depressed mothers (N=14) underwent functional magnetic resonance imaging blood-oxygen-level-dependent acquisition during a block-designed face versus shape matching task. A two-way analysis of variance was performed examining main effects of condition and group and group-by-condition in…

Subgenual cingulate and visual cortex responses to sad faces predict clinical outcome during antidepressant treatment for depression.
Background: Previous follow-up studies indicate that increased visual cortical, ventral cingulate and subcortical responses of depressed individuals to sad facial stimuli, but not happy stimuli could represent reversible markers of disease severity. We hypothesized that greater responses in these areas to sad stimuli, but not happy stimuli, would predict better subsequent clinical outcome. We also explored areas that would predict a poor outcome.
Methods: Twelve melancholically depressed individuals in the early stages of antidepressant treatment in a secondary care setting participated in two experiments comparing responses to varying intensities of sad and happy facial stimuli, respectively, using event related functional MRI. They repeated the experiments after a mean delay of 12 weeks of treatment.
Results: There was a variation in response to treatment. Greater right visual cortex a…

A preliminary investigation of neural correlates of treatment in adolescents with generalized anxiety disorder.
Objective: Generalized anxiety disorder (GAD) is a prevalent and debilitating psychiatric condition of adolescence. Two effective forms of treatment are cognitive behavioral therapy (CBT) and selective serotonin reuptake inhibitors (SSRIs). This pilot study examined changes in brain function following each type of treatment in GAD.
Method: Subjects were 14 youths with GAD (7 had CBT, 7 received fluoxetine) and 10 age- and gender-matched healthy peers. Functional magnetic resonance imaging (fMRI) scans were acquired before and after treatment for patients and over two comparable time points for controls. During fMRI acquisition, a probe detection task with emotional (angry, happy) and neutral faces allowed for assessment of neural response to threat. Following previous research, region of interest analyses were performed in the right ventrolateral prefrontal cortex (VLPFC).
Results: fMRI …

Altered activation and functional connectivity of neural systems supporting cognitive control of emotion in psychosis proneness.
Emotion regulation processes, such as reappraisal, are thought to operate through interactions between prefrontal emotion-control regions and subcortical emotion-generation regions such as the amygdala. Impairments in emotional processing and regulation have been reported in schizophrenia and at-risk populations. Psychometric measures may be used to detect vulnerability to schizophrenia in non-clinical samples, or psychosis proneness (PP). It has been shown that individuals with PP have a more than tenfold increased risk of developing a schizophrenia-spectrum disorder. In the present study, we used fMRI to examine the neural dynamics underlying reappraisal in such a sample. 600 undergraduate students completed the Community Assessment of Psychic Experiences Questionnaire (CAPE), positive subscale. Two groups were subsequently formed from the extremes of the distribution (total N=34). Blo…

Neural responses to masked fear faces: sex differences and trauma exposure in posttraumatic stress disorder.
Although women have a greater propensity than men to develop posttraumatic stress disorder (PTSD) following trauma, sex differences in neural activations to threat have received little investigation. This study tested the prediction that trauma would heighten activity in automatic fear-processing networks to a greater extent in women than in men. Functional magnetic resonance imaging (fMRI) data were recorded in 23 participants with PTSD (13 women, 10 men), 21 trauma-exposed controls (9 women, 12 men), and 42 non-trauma-exposed controls (22 women, 20 men) while they viewed masked facial expressions of fear. Exposure to trauma was associated with enhanced brainstem activity to fear in women, regardless of the presence of PTSD, but in men, it was associated only with the development of PTSD. Men with PTSD displayed greater hippocampal activity to fear than did women. Both men and women wit…

Evidence that oxytocin exerts anxiolytic effects via oxytocin receptor expressed in serotonergic neurons in mice.
The oxytocin receptor has been implicated in the regulation of reproductive physiology as well as social and emotional behaviors. The neurochemical mechanisms by which oxytocin receptor modulates social and emotional behavior remains elusive, in part because of a lack of sensitive and selective antibodies for cellular localization. To more precisely characterize oxytocin receptor-expressing neurons within the brain, we generated an oxytocin receptor-reporter mouse in which part of the oxytocin receptor gene was replaced with Venus cDNA (a variant of yellow fluorescent protein). Examination of the Venus expression revealed that, in the raphe nuclei, about one-half of tryptophan hydroxylase-immunoreactive neurons were positive for Venus, suggesting a potential role for oxytocin in the modulation of serotonin release. Oxytocin infusion facilitated serotonin release within the median raphe n…

Negative bias in fast emotion discrimination in borderline personality disorder.
Background: The ability to decode emotional information from facial expressions is crucial for successful social interaction. Borderline personality disorder (BPD) is characterized by serious problems in interpersonal relationships and emotional functioning. Empirical research on facial emotion recognition in BPD has been sparsely published and results are inconsistent. To specify emotion recognition deficits in BPD more closely, the present study implemented two emotion recognition tasks differing in response format.
Method: Nineteen patients with BPD and 19 healthy subjects were asked to evaluate the emotional content of visually presented stimuli (emotional and neutral faces). The first task, the Fear Anger Neutral (FAN) Test, required a rapid discrimination between negative or neutral facial expressions whereas in the second task, the Emotion Recognition (ER) Test, a precise decision…

Anxiety predicts a differential neural response to attended and unattended facial signals of anger and fear.
Behavioural evidence indicates that individual differences in anxiety influence the response to facial signals of threat. Angry and fearful faces represent qualitatively different forms of threat. Fearful faces are thought to signal the presence of a significant, yet undetermined source of danger within the environment, referred to as 'ambiguous threat'. In contrast, angry faces represent a more direct form of threat, often used in face-to-face encounters to exert dominance. Given the inherent differences between anger and fear, we hypothesised that anxiety would modulate the amygdala response to angry faces to a greater extent when attended. Following previous research, we expected anxiety to show a stronger relationship with the amygdala response to unattended fearful faces. In an event-related fMRI study, we presented images of two houses and two faces (consisting of fearful, angry or…

Molecular distinctions between stasis and telomere attrition senescence barriers shown by long-term culture of normal human mammary epithelial cells.
Normal human epithelial cells in culture have generally shown a limited proliferative potential of approximately 10 to 40 population doublings before encountering a stress-associated senescence barrier (stasis) associated with elevated levels of cyclin-dependent kinase inhibitors p16 and/or p21. We now show that simple changes in medium composition can expand the proliferative potential of human mammary epithelial cells (HMEC) initiated as primary cultures to 50 to 60 population doublings followed by p16-positive, senescence-associated beta-galactosidase-positive stasis. We compared the properties of growing and senescent pre-stasis HMEC with growing and senescent post-selection HMEC, that is, cells grown in a serum-free medium that overcame stasis via silencing of p16 expression and that display senescence associated with telomere dysfunction. Cultured pre-stasis populations contained c…

ERS/ERD and coherence measures of alpha band.
Alpha brain oscillation modulation was analyzed in response to masked emotional facial expressions. In addition, behavioural activation (BAS) and behavioural inhibition systems (BIS) were considered as an explicative factor to verify the effect of motivational significance on cortical activity. Nineteen subjects were submitted to an ample range of facial expressions of emotions (anger, fear, surprise, disgust, happiness, sadness, and neutral). The results demonstrated that anterior frontal sites were more active than central and posterior sites in response to facial stimuli. Moreover, right-side responses varied as a function of emotional types, with an increased right-frontal activity for negative emotions. Finally, whereas higher BIS subjects generated a more right hemisphere activation for some negative emotions (such as fear, anger, and surprise), Reward-BAS subjects were more respon…

Lower CSF oxytocin concentrations in women with a history of childhood abuse.
Early-life disruption of the parent-child relationship, for example, in the form of abuse, neglect or loss, dramatically increases risk for psychiatric, as well as certain medical, disorders in adulthood. The neuropeptide oxytocin (OT) plays a seminal role in mediating social affiliation, attachment, social support, maternal behavior and trust, as well as protection against stress and anxiety. We therefore examined central nervous system OT activity after early-life adversity in adult women. We measured OT concentrations in cerebrospinal fluid (CSF) collected from 22 medically healthy women, aged 18-45 years, categorized into those with none-mild versus those with moderate-severe exposure to various forms of childhood abuse or neglect. Exposure to maltreatment was associated with decreased CSF OT concentrations. A particularly strong effect was identified for emotional abuse. There were …

Individual differences in typical reappraisal use predict amygdala and prefrontal responses.
Background: Participants who are instructed to use reappraisal to downregulate negative emotion show decreased amygdala responses and increased prefrontal responses. However, it is not known whether individual differences in the tendency to use reappraisal manifests in similar neural responses when individuals are spontaneously confronted with negative situations. Such spontaneous emotion regulation might play an important role in normal and pathological responses to the emotional challenges of everyday life.
Methods: Fifty-six healthy women completed a blood oxygenation-level dependent functional magnetic resonance imaging challenge paradigm involving the perceptual processing of emotionally negative facial expressions. Participants also completed measures of typical emotion regulation use, trait anxiety, and neuroticism.
Results: Greater use of reappraisal in everyday life was related …

Context: Serotonin 1A (5-hydroxytryptamine 1A [5-HT(1A)]) autoreceptors mediate negative feedback inhibition of serotonergic neurons and play a critical role in regulating serotonin signaling involved in shaping the functional response of major forebrain targets, such as the amygdala, supporting complex behavioral processes. A common functional variation (C[-1019]G) in the human 5-HT(1A) gene (HTR1A) represents 1 potential source of such interindividual variability. Both in vitro and in vivo, -1019G blocks transcriptional repression, leading to increased autoreceptor expression. Thus, -1019G may contribute to relatively decreased serotonin signaling at postsynaptic forebrain target sites via increased negative feedback.

From specificity to sensitivity: how acute stress affects amygdala processing of biologically salient stimuli.
Background: A vital component of an organism's response to acute stress is a surge in vigilance that serves to optimize the detection and assessment of threats to its homeostasis. The amygdala is thought to regulate this process, but in humans, acute stress and amygdala function have up to now only been studied in isolation. Hence, we developed an integrated design using functional magnetic resonance imaging to investigate the immediate effects of controlled stress induction on amygdala function.
Methods: In 27 healthy female participants, we studied brain responses to emotional facial stimuli, embedded in an either acutely stressful or neutral context by means of adjoining movie clips.
Results: A variety of physiological and psychological measures confirmed successful induction of moderate levels of acute stress. More importantly, this context manipulation shifted the amygdala toward hi…

A functional magnetic resonance imaging study of deliberate emotion regulation in resilience and posttraumatic stress disorder.
Background: Sexual violence is an important public health problem in the United States, with 13% to 26% of women reporting a history of sexual assault. While unfortunately common, there is substantial individual variability in response to sexual assault. Approximately half of rape victims develop posttraumatic stress disorder (PTSD), while others develop no psychopathology (e.g., trauma-exposed non-PTSD). In this project, we examined the neural mechanisms underlying differences in response to sexual violence, focusing specifically on the deliberate modification of emotional responses to negative stimuli.

Oxytocin protects against negative behavioral and autonomic consequences of long-term social isolation.
Positive social interactions and social support may protect against various forms of mental and physical illness, although the mechanisms for these effects are not well identified. The socially monogamous prairie vole, which--like humans--forms social bonds and displays high levels of parasympathetic activity, has provided a useful model for investigating neurobiological systems that mediate the consequences of sociality. In the present study, adult female prairie voles were exposed to social isolation or continued pairing with a female sibling (control conditions) for 4 weeks.

In mammals, the neuropeptide vasopressin is a key molecule for complex emotional and social behaviours. Two microsatellite polymorphisms, RS1 and RS3, near the promoter of AVPR1A, encoding the receptor subtype most heavily implicated in behaviour regulation, have been linked to autism and behavioural traits. However, the impact of these variants on human brain function is unknown. Here we show that human amygdala function is strongly associated with genetic variation in AVPR1A. Using an imaging genetics approach in a sample of 121 volunteers studied with an emotional face-matching paradigm, we found that differential activation of amygdala is observed in carriers of risk alleles for RS3 and RS1. Alleles in RS1 previously reported to be significantly over- and undertransmitted to autistic probands showed opposing effects on amygdala activation. Furthermore, we show functional difference i…

Emotions in motion: dynamic compared to static facial expressions of disgust and happiness reveal more widespread emotion-specific activations.
In social contexts, facial expressions are dynamic in nature and vary rapidly in relation to situational requirements. However, there are very few fMRI studies using dynamic emotional stimuli. The aim of this study was (1) to introduce and evaluate a new stimulus database of static and dynamic emotional facial expressions according to arousal and recognizability investigated by a rating by both participants of the present fMRI study and by an external sample of 30 healthy women, (2) to examine the neural networks involved in emotion perception of static and dynamic facial stimuli separately, and (3) to examine the impact of motion on the emotional processing of dynamic compared to static face stimuli. A total of 16 females participated in the present fMRI study performing a passive emotion perception task including static and dynamic faces of neutral, happy and disgusted expressions. Com…

Enhanced 'Reading the Mind in the Eyes' in borderline personality disorder compared to healthy controls.
Background: Borderline personality disorder (BPD) is partly characterized by chronic instability in interpersonal relationships, which exacerbates other symptom dimensions of the disorder and can interfere with treatment engagement. Facial emotion recognition paradigms have been used to investigate the bases of interpersonal impairments in BPD, yielding mixed results. We sought to clarify and extend past findings by using the Reading the Mind in the Eyes Test (RMET), a measure of the capacity to discriminate the mental state of others from expressions in the eye region of the face.
Method: Thirty individuals diagnosed with BPD were compared to 25 healthy controls (HCs) on RMET performance. Participants were also assessed for depression severity, emotional state at the time of assessment, history of childhood abuse, and other Axis I and personality disorders (PDs).
Results: The BPD group …

Abnormal amygdala-prefrontal effective connectivity to happy faces differentiates bipolar from major depression.
Background: Bipolar disorder is frequently misdiagnosed as major depressive disorder, delaying appropriate treatment and worsening outcome for many bipolar individuals. Emotion dysregulation is a core feature of bipolar disorder. Measures of dysfunction in neural systems supporting emotion regulation might therefore help discriminate bipolar from major depressive disorder.
Methods: Thirty-one depressed individuals-15 bipolar depressed (BD) and 16 major depressed (MDD), DSM-IV diagnostic criteria, ages 18-55 years, matched for age, age of illness onset, illness duration, and depression severity-and 16 age- and gender-matched healthy control subjects performed two event-related paradigms: labeling the emotional intensity of happy and sad faces, respectively. We employed dynamic causal modeling to examine significant among-group alterations in effective connectivity (EC) between right- and …

Fear of negative evaluation and the hypervigilance-avoidance hypothesis: an eye-tracking study.
The hypervigilance-avoidance hypothesis assumes that anxious individuals initially attend to and subsequently avoid threatening stimuli. In this study pairs of emotional (angry or happy) and neutral facial expressions were presented to students of high or low fear of negative evaluation (FNE) while their eye movements were recorded. High FNE participants initially looked more often at emotional compared to neutral faces, indicating an attentional bias for emotional facial expressions. This effect was further modulated by the sex of the face, as high FNE clearly showed a preference for happy female faces. Analysis of the time course of attention revealed that high FNE looked at the emotional faces longer during the first second of stimulus exposure, whereas they avoided these faces in the consecutive time interval from 1 to 1.5 s. These results partially support the hypervigilance-avoidan…
