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

1876 to 1900 of 2,381ERP correlates of attention allocation in mothers processing faces of their children.
This study employed visually evoked event-related potential (ERP) methodology to examine temporal patterns of structural and higher-level face processing in birth and foster/adoptive mothers viewing pictures of their children. Fourteen birth mothers and 14 foster/adoptive mothers engaged in a computerized task in which they viewed facial pictures of their own children, and of familiar and unfamiliar children and adults. All mothers, regardless of type, showed ERP patterns suggestive of increased attention allocation to their own children's faces compared to other child and adult faces beginning as early as 100-150 ms after stimulus onset and lasting for several hundred milliseconds. These data are in line with a parallel processing model that posits the involvement of several brain regions in simultaneously encoding the structural features of faces as well as their emotional and personal…

A left amygdala mediated network for rapid orienting to masked fearful faces.
A rapid response to environmental threat is highly adaptive and fearful facial expressions serve as important threat cues. The biological significance of these threat cues is demonstrated by neuroimaging findings of amygdala responses to backward masked fearful faces. Additionally, behavioral dot-probe studies reveal that backward masked fearful faces modulate spatial attention. However, little is known about the behavioral impact of the amygdala sensitivity to masked fearful faces. Using a dot-probe task with event-related functional magnetic resonance imaging (fMRI), we provide the first evidence that the amygdala is involved in orienting to backward masked fearful faces. Furthermore, this spatial attention-related amygdala response was correlated with activity in the anterior cingulate, superior temporal sulcus, and lingual gyrus.

Event-related delta and theta synchronization during explicit and implicit emotion processing.
Emotion information processing may occur in two modes which are differently represented in conscious awareness. Fast online processing involves coarse-grained analysis of salient features, and is not represented in conscious awareness; offline processing takes hundreds of milliseconds to generate fine-grained analysis, and is represented in conscious awareness. These processing modes may be studied using event-related electroencephalogram theta and delta synchronization as a marker of emotion processing. Two experiments were conducted, which differed on the mode of emotional information presentation. In the explicit mode subjects were explicitly instructed to evaluate the emotional content of presented stimuli; in the implicit mode they performed a gender discrimination task. Firstly, we show that in both experiments theta and delta synchronization is stronger upon presentation of "emoti…

The up- and down-regulation of amusement: experiential, behavioral, and autonomic consequences.
A growing body of research has examined the regulation of negative emotions. However, little is known about the physiological processes underlying the regulation of positive emotions, such as when amusement is enhanced during periods of stress or attenuated in the pursuit of social goals. The aim of this study was to examine the psychophysiological consequences of the cognitive up- and down-regulation of amusement. To address this goal, participants viewed brief, amusing film clips while measurements of experience, behavior, and peripheral physiology were collected. Using an event-related design, participants viewed each film under the instructions either to (a) watch, (b) use cognitive reappraisal to increase amusement, or (c) use cognitive reappraisal to decrease amusement. Findings indicated that emotion experience, emotion-expressive behavior, and autonomic physiology (including hear…

Stop the sadness: Neuroticism is associated with sustained medial prefrontal cortex response to emotional facial expressions.
Neuroticism is a personality trait associated with negative mood states, sensitivity to negative information, negative appraisal and vulnerability to psychopathology. Previous studies have associated the sustained processing of negative information (words) with individual differences such as rumination and depression but not with personality. In the current study, we aimed to investigate the relationship between neuroticism and changes in sustained patterns of activity within a brain region implicated in emotional self-evaluation and appraisal, the Medial Prefrontal Cortex (MedPFC), when responding to emotional facial expressions (happy, fearful, and sad). We tested whether higher scores of neuroticism are associated with greater sustained patterns of brain activity in the MedPFC when responding to blocks of negative facial expressions. We found that higher scores of neuroticism were ass…

Oxytocin reduces anxiety via ERK1/2 activation: local effect within the rat hypothalamic paraventricular nucleus.
The neuropeptide oxytocin (OT) modulates social behaviours and is an important anxiolytic substance of the brain. However, sites of action and the intracellular signalling pathways downstream of OT receptors (OTR) within the brain remain largely unknown. In the present studies, we localized the anxiolytic effect of OT by bilateral microinfusion of OT (0.01 nmol/0.5 microL) into the hypothalamic paraventricular nucleus (PVN) in male rats using both the elevated plus-maze and the light-dark box. Moreover, intracerebroventricular administration of OT, but not of the related neuropeptide vasopressin (VP), dose-dependently activated the extracellular signal-regulated kinase 1/2 (ERK1/2) cascade. Specifically, OT induced the phosphorylation of Raf-1, MEK1/2 and ERK1/2 in the hypothalamus in vivo and in hypothalamic H32 neurons via EGF receptors. OT-induced ERK1/2 phosphorylation was immunohist…

Perception of emotional expressions is independent of face selectivity in monkey inferior temporal cortex.
The ability to perceive and differentiate facial expressions is vital for social communication. Numerous functional MRI (fMRI) studies in humans have shown enhanced responses to faces with different emotional valence, in both the amygdala and the visual cortex. However, relatively few studies have examined how valence influences neural responses in monkeys, thereby limiting the ability to draw comparisons across species and thus understand the underlying neural mechanisms. Here we tested the effects of macaque facial expressions on neural activation within these two regions using fMRI in three awake, behaving monkeys. Monkeys maintained central fixation while blocks of different monkey facial expressions were presented. Four different facial expressions were tested: (i) neutral, (ii) aggressive (open-mouthed threat), (iii) fearful (fear grin), and (iv) submissive (lip smack). Our results…

Dissociative responses to conscious and non-conscious fear impact underlying brain function in post-traumatic stress disorder.
Background: Dissociative reactions in post-traumatic stress disorder (PTSD) have been regarded as strategic responses that limit arousal. Neuroimaging studies suggest distinct prefrontal responses in individuals displaying dissociative and hyperarousal responses to threat in PTSD. Increased prefrontal activity may reflect enhanced regulation of limbic arousal networks in dissociation. If dissociation is a higher-order regulatory response to threat, there may be differential responses to conscious and automatic processing of threat stimuli. This study addresses this question by examining the impact of dissociation on fear processing at different levels of awareness.
Method: Functional magnetic resonance imaging (fMRI) with a 1.5-T scanner was used to examine activation to fearful (versus neutral) facial expressions during consciously attended and non-conscious (using backward masking) con…

Objective: Generalized social phobia involves fear/avoidance, specifically of social situations, whereas generalized anxiety disorder involves intrusive worry about diverse circumstances. It remains unclear the degree to which these two, often comorbid, conditions represent distinct disorders or alternative presentations of a single, core underlying pathology. Functional magnetic resonance imaging assessed the neural response to facial expressions in generalized social phobia and generalized anxiety disorder.

Amygdala and ventral anterior cingulate activation predicts treatment response to cognitive behaviour therapy for post-traumatic stress disorder.
Background: Although cognitive behaviour therapy (CBT) is the treatment of choice for post-traumatic stress disorder (PTSD), approximately half of patients do not respond to CBT. No studies have investigated the capacity for neural responses during fear processing to predict treatment response in PTSD.
Method: Functional magnetic resonance imaging (fMRI) responses of the brain were examined in individuals with PTSD (n=14). fMRI was examined in response to fearful and neutral facial expressions presented rapidly in a backwards masking paradigm adapted for a 1.5 T scanner. Patients then received eight sessions of CBT that comprised education, imaginal and in vivo exposure, and cognitive therapy. Treatment response was assessed 6 months after therapy completion.
Results: Seven patients were treatment responders (defined as a reduction of 50% of pretreatment scores) and seven were non-respon…

Responses of single neurons in monkey amygdala to facial and vocal emotions.
The face and voice can independently convey the same information about emotion. When we see an angry face or hear an angry voice, we can perceive a person's anger. These two different sensory cues are interchangeable in this sense. However, it is still unclear whether the same group of neurons process signals for facial and vocal emotions. We recorded neuronal activity in the amygdala of monkeys while watching nine video clips of species-specific emotional expressions: three monkeys showing three emotional expressions (aggressive threat, scream, and coo). Of the 227 amygdala neurons tested, 116 neurons (51%) responded to at least one of the emotional expressions. These "monkey-responsive" neurons-that is, neurons that responded to monkey-specific emotional expression-preferred the scream to other emotional expressions irrespective of identity. To determine the element crucial to neuronal…

Exploring the nature of facial affect processing deficits in schizophrenia.
Schizophrenia has been associated with deficits in facial affect processing, especially negative emotions. However, the exact nature of the deficit remains unclear. The aim of the present study was to investigate whether schizophrenia patients have problems in automatic allocation of attention as well as in controlled evaluation of facial affect. Thirty-seven patients with schizophrenia were compared with 41 control subjects on incidental facial affect processing (gender decision of faces with a fearful, angry, happy, disgusted, and neutral expression) and degraded facial affect labeling (labeling of fearful, angry, happy, and neutral faces). The groups were matched on estimates of verbal and performance intelligence (National Adult Reading Test; Raven's Matrices), general face recognition ability (Benton Face Recognition), and other demographic variables. The results showed that patient…

Is a lack of disgust something to fear? A functional magnetic resonance imaging facial emotion recognition study in euthymic bipolar disorder patients.
Objectives: To determine the neural responses invoked in the recognition of facial fear and disgust in euthymic bipolar patients as compared with healthy subjects.
Methods: This study examined 10 female euthymic bipolar patients, and 10 suitably matched healthy subjects using functional magnetic resonance imaging (fMRI) while subjects were engaged in an explicit facial emotion recognition task involving fear, disgust and neutral expressions. The activation paradigm involved nominating the facial expression using specified response keys. Behavioural data were collected and analysed and both within-group (Fear versus Neutral; Disgust versus Neutral) and random-effects between-group analyses were performed on fMRI data using BrainVoyager (Brain Innovations, Maastricht, the Netherlands).
Results: Patients were equally accurate in identifying facial expressions as healthy subjects but were sl…

Anxiety and orienting of gaze to angry and fearful faces.
Neuroscience research indicates that individual differences in anxiety may be attributable to a neural system for threat-processing, involving the amygdala, which modulates attentional vigilance, and which is more sensitive to fearful than angry faces. Complementary cognitive studies indicate that high-anxious individuals show enhanced visuospatial orienting towards angry faces, but it is unclear whether fearful faces elicit a similar attentional bias. This study compared biases in initial orienting of gaze to fearful and angry faces, which varied in emotional intensity, in high- and low-anxious individuals. Gaze was monitored whilst participants viewed a series of face-pairs. Results showed that fearful and angry faces elicited similar attentional biases. High-anxious individuals were more likely to direct gaze at intense negative facial expressions, than low-anxious individuals, wherea…

Modulation of emotional appraisal by false physiological feedback during fMRI.
Background: James and Lange proposed that emotions are the perception of physiological reactions. Two-level theories of emotion extend this model to suggest that cognitive interpretations of physiological changes shape self-reported emotions. Correspondingly false physiological feedback of evoked or tonic bodily responses can alter emotional attributions. Moreover, anxiety states are proposed to arise from detection of mismatch between actual and anticipated states of physiological arousal. However, the neural underpinnings of these phenomena previously have not been examined.
Methodology/principal findings: We undertook a functional brain imaging (fMRI) experiment to investigate how both primary and second-order levels of physiological (viscerosensory) representation impact on the processing of external emotional cues. 12 participants were scanned while judging face stimuli during both …

Facial emotion discrimination across the menstrual cycle in women with premenstrual dysphoric disorder (PMDD) and controls.
Background: Depressed patients show mood-congruent errors in the identification of emotion in facial expressions. Errors consist of impaired performance (recognition errors) and negative bias (seeing faces as sadder than they are). This abnormal processing may both reflect and contribute to the negative affective state. In this study, we administered an emotional recognition in facial expression task to women with premenstrual dysphoric disorder (PMDD) to determine whether processing errors similar to those in depression were present and whether they were confined to the luteal phase (i.e., state dependent).
Methods: The Facial Discrimination Task (FDT) was administered in the follicular and luteal phases to women with PMDD (n=28) and asymptomatic controls (n=27).
Results: ANOVA with repeated measures identified significantly increased negative judgments (both performance errors and bias…

The world of emotions is not two-dimensional.
For more than half a century, emotion researchers have attempted to establish the dimensional space that most economically accounts for similarities and differences in emotional experience. Today, many researchers focus exclusively on two-dimensional models involving valence and arousal. Adopting a theoretically based approach, we show for three languages that four dimensions are needed to satisfactorily represent similarities and differences in the meaning of emotion words. In order of importance, these dimensions are evaluation-pleasantness, potency-control, activation-arousal, and unpredictability. They were identified on the basis of the applicability of 144 features representing the six components of emotions: (a) appraisals of events, (b) psychophysiological changes, (c) motor expressions, (d) action tendencies, (e) subjective experiences, and (f) emotion regulation.

Neural dynamics for facial threat processing as revealed by gamma band synchronization using MEG.
Facial threat conveys important information about imminent environmental danger. The rapid detection of this information is critical for survival and social interaction. However, due to technical and methodological difficulties, the spatiotemporal profile for facial threat processing is unknown. By utilizing magnetoencephalography (MEG), a brain-imaging technique with superb temporal resolution and fairly good spatial resolution, Synthetic Aperture Magnetometry (SAM), a recently developed source analysis technique, and a sliding window analysis, we identified the spatiotemporal development of facial threat processing in the gamma frequency band. We also tested the dual-route hypothesis by LeDoux who proposed, based on animal research, that there are two routes to the amygdala: a quick subcortical route and a slower and cortical route. Direct evidence with humans supporting this model has…

Emotion induction after direct intracerebral stimulations of human amygdala.
Very few studies in humans have quantified the effect obtained after direct electrical stimulation of the amygdala, in terms of both emotional and physiological responses. We tested patients with drug-resistant partial epilepsies who were explored with intracerebral electrodes in the setting of presurgical evaluation. We assessed the effects of direct electric stimulations in either the right or the left amygdala on verbally self-reported emotions (Izard scale) and on psychophysiological markers of emotions by recording skin conductance responses (SCRs) and by measuring the electromyographic responses of the corrugator supercilii (EMGc). According to responses on Izard scales, electrical stimulations of the right amygdala induced negative emotions, especially fear and sadness. In contrast, stimulations of the left amygdala were able to induce either pleasant (happiness) or unpleasant (fe…

Blunted rostral anterior cingulate response during a simplified decoding task of negative emotional facial expressions in alcoholic patients.
Background: Alcoholism is characterized by deficits in emotional functioning as well as by deficits in cognitive functioning. However, most brain imaging research on alcoholism has focused on cognition rather than emotion.
Method: We used an event-related functional magnetic imaging approach to examine alcoholics' brain blood oxygenation level dependent (BOLD) response to evaluation of emotional stimuli and to compare their response to that of nonalcoholic controls. The task used was a simplified variant of a facial emotion-decoding task in which subjects determined the intensity level of a target emotion displayed as a facial expression. Facial expressions of happy, sad, anger, disgust, and fear were used as stimuli.
Results: Alcoholics and controls did not differ in accurately identifying the intensity level on the simple emotional decoding task but there were significant differences i…

Impact of voice on emotional judgment of faces: an event-related fMRI study.
Emotional information can be conveyed by various means of communication, such as propositional content, speech intonation, facial expression, and gestures. Prior studies have demonstrated that inputs from one modality can alter perception in another modality. To evaluate the impact of emotional intonation on ratings of emotional faces, a behavioral study first was carried out. Second, functional magnetic resonance (fMRI) was used to identify brain regions that mediate crossmodal effects of emotional prosody on judgments of facial expressions. In the behavioral study, subjects rated fearful and neutral facial expressions as being more fearful when accompanied by a fearful voice as compared to the same facial expressions without concomitant auditory stimulus, whereas no such influence on rating of faces was found for happy voices. In the fMRI experiment, this shift in rating of facial expr…

Brain responses to dynamic facial expressions of pain.
The facial expression of pain is a prominent non-verbal pain behaviour, unique and distinct from the expression of basic emotions. Yet, little is known about the neurobiological basis for the communication of pain. Here, subjects performed a sex-discrimination task while we investigated neural responses to implicit processing of dynamic visual stimuli of male or female faces displaying pain or angry expressions, matched on expression intensity and compared to neutral expression. Stimuli were presented in a mixed blocked/event-related design while blood oxygenation level dependent (BOLD) signal was acquired using whole-brain functional magnetic resonance imaging (fMRI) at 1.5 Tesla. Comparable sustained responses to pain and angry faces were found in the superior temporal sulcus (STS). Stronger transient activation was also observed to male expression of pain (Vs neutral and anger) in hig…

Autonomic and neuroendocrine responses to a psychosocial stressor in adults with autistic spectrum disorder.
Objective of the study was to replicate in adults our previous findings of decreased heart rate and normal endocrine responses to stress in autistic children and to elucidate the discrepancy between autonomic and endocrine stress responses by including epinephrine, norepinephrine, oxytocin and vasopressin measurements. Ten autistic spectrum disorder (ASD) adults were compared to 14 healthy controls in their response to a psychosocial stressor (public speaking). ASD patients showed decreased heart rate, but normal cortisol responses, consistent with our prior findings in children. No differences in norepinephrine, epinephrine, oxytocin or vasopressin responses to stress were found. However, in contrast to previous findings in low functioning autistic children, ASD adults showed increased basal oxytocin levels, which may be related to developmental factors.
