Using intracranial local field potential (LFP) recordings in patients with Parkinson's disease (PD) undergoing deep brain stimulation (DBS), we explored the electrophysiological activity of the subthalamic nucleus (STN) in response to emotional stimuli in the auditory modality. Previous studies focused on the influence of visual stimuli. To this end, we recorded LFPs within the STN in response to angry, happy, and neutral prosodies in 13 patients with PD who had just undergone implantation of DBS electrodes...

A considerable amount of marketing research has reported that consumers are more saliently influenced by friends (strong social ties) than by acquaintances and strangers (weak social ties). To shed light on the neural and psychological processes underlying such phenomenon, in this study we designed an amended S1-S2 paradigm (product-[reviewer-review]) that is based on realistic consumer purchase experiences. After incoming all given information (product, reviewer, review), participants were required to state their purchase intentions...

The emotional state, psychological characteristics, cognitive function, and the relevance among above factors in patients with functional constipation (FC) are complex. This study aimed to investigate whether FC symptoms might be related to implicit processing such as psychological characteristics and emotional somatization.Thirty-five FC patients and 24 normal volunteers were recruited to collect event-related potentials (ERP) behavior and electroencephalogram data when simple digital GoNogo visual tasks were performed...

Using ERPs, we explored the relationship between social power and emotional prosody processing. In particular, we investigated differences at early and late processing stages between individuals primed with high or low power. Comparable to previously published findings from nonprimed participants, individuals primed with low power displayed differentially modulated P2 amplitudes in response to different emotional prosodies, whereas participants primed with high power failed to do so. Similarly, participants primed with low power showed differentially modulated amplitudes in response to different emotional prosodies at a later processing stage (late ERP component), whereas participants primed with high power did not...

The current study combined multiple levels of analysis to examine whether disrupted neural and pupillary reactivity to emotional faces serves as a state- or trait-like marker of adolescent major depressive disorder (MDD). The study examined differences in pupil dilation and the event-related potential (ERP) late positive potential (LPP) component to emotional faces before and after a negative mood induction between 71 adolescents (age 11-18 years) with (i) a current diagnosis of MDD, (ii) a past episode of MDD currently in full remission, and (iii) no lifetime history of any Axis I disorder...

OBJECTIVE: Stress, pain, injury, and psychological trauma all induce arousal-mediated changes in brain network organization. The associated, high level of arousal may disrupt motor-sensory processing and result in aberrant patterns of motor function, including functional neurological symptoms. We used the auditory oddball paradigm to assess cortical arousal in children and adolescents with functional neurological symptom disorder. METHOD: Electroencephalogram (EEG) data was collected in fifty-seven children and adolescents (41 girls; 16 boys, aged 8...

Theory and research indicate considerable influence of socio-emotionally significant experiences on children's functioning and adaptation. In the current study, we examined neurophysiological correlates of children's allocation of information processing resources to socio-emotionally significant events, specifically, simulated marital interactions. We presented 9- to 11-year-old children (n=24; 11 females) with 15 videos of interactions between two actors posing as a married couple. Task-irrelevant brief auditory probes were presented during the videos, and event-related potentials (ERPs) elicited to the auditory probes were measured...

Despite extensive research on action-effect anticipation, little attention has been paid to the anticipation of different attributes of an event. An action-effect is not only a sensory event; it is often also an event of emotional value which can be pleasant or aversive. This latter attribute of action-effect prediction is similar to anticipation of reward versus punishment. To date the neural systems controlling sensory and reward anticipation have not been systematically compared. To this end, we designed an experiment to manipulate the sensory content and the emotional valence of the stimuli in an orthogonal fashion...

OBJECTIVE: The reduction of the amplitude of the late positive potential (LPP) following cognitive reappraisal has been used as a neural marker of emotion regulation. However, studies employing this neural marker in children are scarce and findings are not conclusive, with most studies showing a lack of LPP modulation after reappraisal in children in the age range of 5-12 years. The aim of the current study was therefore to investigate developmental changes in sensitivity of LPP modulation to cognitive reappraisal...

Often we know whether an upcoming event is going to be good or bad. But does that knowledge help us regulate ensuing emotions? To address this question, we exposed participants to alleged social feedback that was either positive or negative. On half the trials, a preceding cue indicated the feedback's affective quality. On the remaining trials, the cue was uninformative. In two different blocks, participants either appraised feedback spontaneously or down-regulated ensuing emotions using a controlled appraisal strategy...

Childhood adversity plays an important role for development of major depressive disorder (MDD). There are differences in subcortical brain structures between patients with MDD and healthy controls, but the specific impact of childhood adversity on such structures in MDD remains unclear. Thus, aim of the present study was to investigate whether childhood adversity is associated with subcortical volumes and how it interacts with a diagnosis of MDD and sex. Within the ENIGMA-MDD network, nine university partner sites, which assessed childhood adversity and magnetic resonance imaging in patients with MDD and controls, took part in the current joint mega-analysis...

Emotional sensitivity and impulsivity could cause interpersonal conflicts and neuropsychiatric problems. Serotonin is correlated with behavioral inhibition and impulsivity. This study evaluated whether the loudness dependence of auditory evoked potential (LDAEP), a potential biological marker of central serotonergic activity, could reflect emotional sensitivity and impulsivity. A total of 157 healthy individuals were recruited, who performed LDAEP and Go/Nogo paradigms during electroencephalogram measurement...

Recently, research on lateralized event related potentials (ERPs) in response to irrelevant distractors has revealed that angry but not happy schematic distractors capture spatial attention. Whether this effect occurs in the context of the natural expression of emotions is unknown. To fill this gap, observers were asked to judge the gender of a natural face surrounded by a color singleton among five other face identities. In contrast to previous studies, the similarity between the task-relevant feature (color) and the distractor features was low...

Cheng Chen, Kaibin Jin, Yehua Li, Hongmei Yan
The relationship between emotion and attention has fascinated researchers for decades. Many previous studies have used eye-tracking, ERP, MEG, and fMRI to explore this issue but have reached different conclusions: some researchers hold that emotion cognition is an automatic process and independent of attention, while some others believed that emotion cognition is modulated by attentional resources and is a type of controlled processing. The present research aimed to investigate this controversy, and we hypothesized that the attentional dependence of emotion cognition is variable with the competing task...

Deficient self-regulation plays a key role in the etiology of early onset disruptive behavior disorders and signals risk for chronic psychopathology. However, to date, there has been no research comparing preschool children with and without high levels of disruptive behavior using Event Related Potentials (ERPs) associated with specific self-regulation sub-processes. We examined 15 preschool children with high levels of disruptive behavior (35 % female) and 20 peers with low disruptive behavior (50 % female) who completed a Go/No-go task that provided emotionally valenced feedback...

Emotional items are often remembered more clearly than neutral items. However, whether stimuli embedded in an emotional context are more resistant to directed forgetting than those presented in a neutral context remains unclear. This question was tested by recording event-related potentials (ERPs) in an item-method directed forgetting paradigm involving neutral words that were embedded in neutral or negative contexts. During the study phase, participants were asked to associate a neutral word with a negative or neutral picture...

Although previous studies have shown that patients with multiple sclerosis (MS) may exhibit impaired decision making (DM), the specific neuro-cognitive processes that underlie this deficiency remain unknown. Inefficient DM may occur due to poor option assessment or a deficit in the evaluation of choice outcomes. This study uses, for the first time, the event-related potential (ERP) technique to analyze these DM subprocesses in patients with MS. Sixteen MS patients and nineteen control subjects performed a DM task based on the Iowa Gambling Task while a digital EEG was recorded...

In this study, to investigate the influence of incidental emotions on decision making in high-anxious individuals, participants were required to perform a monetary gambling task. Behavioral and electroencephalography responses were recorded to explore the stages of option assessment and outcome evaluation during decision making, respectively. Incidental emotions were elicited by facial expression pictures presented on the background, which included four conditions (control, neutral, fearful, and happy). Results showed smaller feedback-related negativity (FRN) amplitudes in high-anxious participants than low-anxious participants in the control, neutral, and fearful conditions, but not in the happy condition, for small outcomes...

Obsessive-compulsive disorder (OCD) is a frequent and severe disease, potentially inducing a major impairment for the patient and burden for their family. Recent research in psychiatry and neuroscience have led to better comprehension of the disease's mechanisms and helped to improve its treatment. However, a large proportion of patients have refractory symptoms, including for traditional cognitive and behavioral therapy by exposure and response prevention (ERP), leading clinicians to look for new treatments...
