Microbial metabolites are known to affect immune system, brain, and behavior via activation of pattern recognition receptors such as Toll-like receptor 4 (TLR4). Unlike the effect of the TLR4 agonist lipopolysaccharide (LPS), the role of other TLR agonists in immune-brain communication is insufficiently understood. We therefore hypothesized that the TLR2 agonist lipoteichoic acid (LTA) causes immune activation in the periphery and brain, stimulates the hypothalamic-pituitary-adrenal (HPA) axis and has an adverse effect on blood-brain barrier (BBB) and emotional behavior...

: Background/Study Context: Many studies have found age-related declines in emotion recognition, with older adult (OA) deficits strongest for negative emotions. Some evidence suggests that OA also show worse performance in decoding complex mental states. However, no research has investigated whether those deficits are stronger for negative states. METHODS: The authors investigated OA (ages 65-93) and younger adult (YA; ages 18-22) performance on the Reading the Mind in the Eyes Test (RME), a well-validated measure of the ability to decode complex mental states from faces...

Although emotion detection using electroencephalogram (EEG) data has become a highly active area of research over the last decades, little attention has been paid to stimulus familiarity, a crucial subjectivity issue. Using both our experimental data and a sophisticated database (DEAP dataset), we investigated the effects of familiarity on brain activity based on EEG signals. Focusing on familiarity studies, we allowed subjects to select the same number of familiar and unfamiliar songs; both resulting datasets demonstrated the importance of reporting self-emotion based on the assumption that the emotional state when experiencing music is subjective...

This paper illustrates the wavelet-based feature extraction for emotion assessment using electroencephalogram (EEG) signal through graphical coding design. Two-dimensional (valence-arousal) emotion model was studied. Different emotions (happy, joy, melancholy, and disgust) were studied for assessment. These emotions were stimulated by video clips. EEG signals obtained from four subjects were decomposed into five frequency bands (gamma, beta, alpha, theta, and delta) using "db5" wavelet function. Relative features were calculated to obtain further information...

Emotional processing dysfunction is widely reported in patients with chronic schizophrenia and first-episode psychosis (FEP), and has been linked to functional abnormalities of corticolimbic regions. However, corticolimbic dysfunction is less studied in people at ultra-high risk for psychosis (UHR), particularly during processing prosodic voices. We examined corticolimbic response during an emotion recognition task in 18 UHR participants and compared them with 18 FEP patients and 21 healthy controls (HC). Emotional recognition accuracy and corticolimbic response were measured during functional magnetic resonance imaging (fMRI) using emotional dynamic facial and prosodic voice stimuli...

INTRODUCTION: The Klinefelter syndrome (KS) is a genetic condition characterized by an X supernumerary sex chromosome in males. The syndrome is frequently associated with cognitive impairment. Indeed, the different areas of the executive sphere can be affected such as inhibition, cognitive flexibility but also attentional and visual-spatial domain. Social cognition disorders, predominantly on emotional recognition processes, have also been documented. In addition, the syndrome may be associated with psychiatric symptoms...

People typically remember emotionally negative words better than neutral words. Two experiments are reported that investigate whether emotionally enhanced memory (EEM) for negatively arousing words is based on a storage or retrieval advantage. Participants studied non-word-word pairs that either involved negatively arousing or neutral target words. Memory for these target words was tested by means of a recognition test and a cued-recall test. Data were analysed with a multinomial model that allows the disentanglement of storage and retrieval processes in the present recognition-then-cued-recall paradigm...

INTRODUCTION: Amyotrophic lateral sclerosis (ALS) primarily impairs motor abilities but also affects cognition and emotional processing. We hypothesise that subjective ratings of emotional stimuli depicting social interactions and facial expressions is changed in ALS. It was found that recognition of negative emotions and ability to mentalize other's intentions is reduced. METHODS: Processing of emotions in faces was investigated. A behavioural test of Ekman faces expressing six basic emotions was presented to 30 ALS patients and 29 age-, gender and education matched healthy controls...

Takotsubo Cardiomyopathy (TC) is also known as Stress Induced Cardiomyopathy or Broken Heart Syndrome. Typically there is transient systolic dysfunction of the apical or the mid segments of the left ventricle that occurs in the presence of acute emotional stress. Some atypical variants have been described. Hyperadrenergic state associated with emotional stress is cited as the probable etiology. It mimics Acute Myocardial Infarction with concomitant rise in cardiac biomarkers, ECG, 2D-Echocardiography abnormalities comprising of left ventricular dysfunction with regional wall motion abnormality, no significant Coronary Artery Disease on angiography...

People tend to mimic the facial expression of others. It has been suggested that this helps provide social glue between affiliated people but it could also aid recognition of emotions through embodied cognition. The degree of facial mimicry, however, varies between individuals and is limited in people with autism spectrum conditions (ASC). The present study sought to investigate the effect of promoting facial mimicry during a facial-emotion-recognition test. In two experiments, participants without an ASC diagnosis had their autism quotient (AQ) measured...

OBJECTIVE: Social cognition is recognized to be a deficit in individuals suffering from schizophrenia. Numerous studies have explored the relationship between social cognition and social functioning in outpatients with schizophrenia through the use of different social cognition training programs. This study examines the efficacy of the Social Cognition Training Program (PECS in Spanish) in adults with a diagnosis of schizophrenia. METHODS: Data were derived from a sample of 44 non-hospitalized adult patients who presented with a DSM-IV-TR Axis I diagnosis of schizophrenia and 39 healthy controls...

Increasing recognition that apathy is one of the most prevalent behavioral and psychological symptoms of dementia and causes substantial caregiver distress has led to trials evaluating psychosocial and pharmacological treatments of apathy in dementia. We evaluated evidence of the efficacy of pharmacotherapies for apathy in dementia from studies since 2013. Previously reported benefits of acetylcholinesterase inhibitors and memantine were not replicated in recent studies. Antidepressants had mixed results with positive effects for apathy shown only for agomelatine, while stimulants, analgesics, and oxytocin study results were inconclusive...

While aging is generally associated with episodic memory decline, not all older adults exhibit memory loss. Furthermore, emotional memories are not subject to the same extent of forgetting and appear preserved in aging. We conducted high-resolution fMRI during a task involving pattern separation of emotional information in older adults with and without age-related memory impairment (characterized by performance on a word-list learning task: low performers: LP vs. high performers: HP). We found signals consistent with emotional pattern separation in hippocampal dentate (DG)/CA3 in HP but not in LP individuals, suggesting a deficit in emotional pattern separation...

Although we encounter numerous expressive faces on a daily basis, those that are not aimed at us will often be disregarded. Facial expressions aimed at our direction appear far more relevant and evoke an engaging affective experience, while the exact same expressions aimed away from us may not. While the importance of expression directionality is intuitive and commonplace, the neural mechanisms underlying this phenomenon are largely unknown. In the current study we measured EEG mu rhythm suppression, an established measure of mirror neuron activity, while participants viewed short video clips of dynamic facial expressions...

BACKGROUND: Emotionally salient experiences induce the formation of explicit memory traces, besides eliciting automatic or implicit emotional memory in rodents. This study aims at investigating the implementation of a novel task for studying the formation of limbic memory engrams as a result of the acquisition- and retrieval- of fear-conditioning - biased declarative memory traces, measured by animal discrimination of an "emotional-object". Moreover, by using this new method we investigated the potential interactions between stimulation of cannabinoid transmission and integration of emotional information and cognitive functioning...

BACKGROUND: Williams syndrome (WS) is a genetic condition characterized by an unusual "hypersocial" personality juxtaposed by high anxiety. Recent evidence suggests that autonomic reactivity to affective face stimuli is disorganised in WS, which may contribute to emotion dysregulation and/or social disinhibition. METHODS: Electrodermal activity (EDA) and mean interbeat interval (IBI) of 25 participants with WS (19 - 57 years old) and 16 typically developing (TD; 17-43 years old) adults were measured during a passive presentation of affective face and voice stimuli...

Normal adult aging is associated with difficulties in processing social cues to emotions such as anger and also altered motivation to focus more on positive than negative information. Gaze direction is an important modifier of the social signals conveyed by an emotion, for example, an angry face looking directly at you is considerably more threatening than an angry face looking away. In the present study we tested the hypothesis that older adults would show less neural differentiation to angry faces with direct and avert gaze compared to younger people, with the opposite prediction for happy faces...

Deficits in emotion processing (EP) represent a target of rehabilitation in schizophrenia, as they have been related to poor personal and social functioning. To date neither the relationship between these deficits and the generalised cognitive impairment, nor the involvement of specific mechanisms of perception (visual or auditory) are fully comprehended. We developed two treatments targeting EP, through visual or auditory channels, with the aim of disentangling possible differences and/or interactions between the two modalities in schizophrenia-related impairments, also taking into account the role of cognition and social functioning...

The core symptoms of Autism Spectrum Disorder (ASD) include impaired social communication, repetitive behaviors and restricted interests. No effective pharmacotherapy for these core deficits exists. Within the domain of social communication, the vasopressin system is implicated in social cognition and social signaling deficits of ASD, and represents a potential therapeutic target. We assessed the effects of a single 20 mg intravenous dose of the arginine vasopressin receptor 1A (V1a) antagonist, RG7713, on exploratory biomarkers (eye-tracking), behavioral and clinical measures of social cognition and communication (affective speech recognition [ASR], reading the mind in the eyes [RMET], olfactory identification, scripted interaction), and safety and tolerability in a multicenter, randomized, double-blind, placebo-controlled, cross-over study of 19 high-functioning adult male subjects with DSM-IV Autistic Disorder (age 18-45 years; full scale IQ>70; ABC-Irritability subscale ⩽13)...

Multiple disorders once jointly conceived as 'nervous diseases' became segregated by the distinct institutional traditions forged in neurology and psychiatry. As a result, each field specialized in the study and treatment of a subset of such conditions. Here we propose new avenues for interdisciplinary interaction through a triangulation of both fields with social neuroscience. To this end, we review evidence from five relevant domains (facial emotion recognition, empathy, theory of mind, moral cognition, social context assessment), highlighting their common disturbances across neurological and psychiatric conditions and discussing their multiple pathophysiological mechanisms...
