Annoyance to unwanted sound differs across individuals, though why noise sensitive individuals are more reactive to noise while others are more resilient remains unanswered. The Information Processing Hypothesis posits that noise sensitive individuals are vulnerable to higher-order auditory processing deficits. The aim of this study was to test the veracity of this hypothesis by documenting differences in pre-attentive auditory evoked potentials (ERP) between high noise sensitive and low noise sensitive individuals...

The present study aimed to investigate the alterations of psychophysiological responses to empathy for pain among patients with somatoform pain disorder (SPD). Behavioral and event-related potential (ERP) responses to pictures depicting hands or feet in different non-painful or painful situations were compared between 18 SPD patients and 18 healthy controls. Patients with SPD reported lower unpleasantness to the observation of others' pain than healthy controls, thus suggesting a reduced affective sharing to others' pain in SPD...

A number of studies have shown that the pupil dilates during stimuli recognition and decision-making. Yet, little is known about the interaction between recognition memory and decision processes. Here, we investigated the possible link between pupil response and decision-related factors during a visual recognition task. Forty-eight volunteers took part in the study. The experimental task was based on the Deese-Roediger-McDermott paradigm designed to study false recognitions. Participants were shown different sets of two meaningless objects...

Event-related oscillatory responses reflect the cognitive status in many neuropsychiatric conditions including mild cognitive impairment (MCI). In this study, a total of 30 patients with amnestic MCI (aMCI) and 25 patients with MCI of Parkinson's disease (PD-MCI) were compared with 28 aged-, gender-, education-matched healthy control (HC) participants using visual event-related delta, theta, alpha oscillatory responses by methods of event-related spectral perturbation and inter-trial coherence. PD-MCI and aMCI groups commonly share a decreased theta power, but all electrophysiological deviations from the controls were more prominent in PD-MCI than aMCI in all frequency bands...

Mismatch negativity (MMN) reduction is one of the most robust findings among several neurophysiological and neurocognitive measures in patients with schizophrenia. MMN is a promising biomarker for schizophrenia because of the following properties: 1) its relationship with early psychosis, including clinical high-risk (CHR); 2) its relationship with the functional abilities of patients; and 3) its translatability into basic research using animal models. Specifically, the utility of the passive auditory oddball paradigm that does not require subjects to make behavioral responses enables identical physiological activities to be obtained from both experimental animals and patients...

Deep slow breathing can increase vagal nerve activity, indexed by heart rate variability (HRV). HRV is also associated with better decision-making. This research examined the effects of two breathing patterns on HRV (Study 1) and on stress and decision-making performance (Study 2). In Study 1, 30 healthy people performed either a symmetric breathing pattern (equal ratio of inhaling/exhalation timing), a skewed pattern (exhalation longer than inhalation), or watched an emotionally neutral film (sham), following a baseline period...

Cognitive impairment is common and debilitating in persons with multiple sclerosis (MS), and further is poorly-managed by pharmacotherapy. Cognitive rehabilitation and exercise training have been identified as promising behavioral approaches for managing MS-related cognitive impairment based on systematic reviews and meta-analyses. However, each body of literature is associated with similar sets of methodological shortcomings, as has been identified by periodic systematic reviews and meta-analyses. Thus, there is little generalizability or transportability research supporting either behavioral approach for managing cognitive dysfunction in this population under real-world conditions (i...

Eye movements are considered to be informative with regard to the underlying cognitive processes of human beings. Previous studies have reported that eye movements are associated with which scientific concepts are retrieved correctly. Moreover, other studies have also suggested that eye movements involve the cooperative activity of the human brain's fronto-parietal circuits. Less research has been conducted to investigate whether fronto-parietal EEG oscillations are associated with the retrieval processing of scientific concepts...

BACKGROUND: Borderline Personality Disorder (BPD) is characterized by emotional instability, impulsivity, disturbed cognition, sleeplessness and states of high inner tension. Altered arousal regulation which is regarded as a higher domain of functioning according to the research domain criteria of the NIMH and which has previously been reported in several psychiatric disorders, such as mania or major depression could be involved in these features of BPD. METHODS: 40 unmedicated patients with BPD and 42 matched healthy volunteers participated in a twenty minute resting-state EEG measurement with closed eyes...

Neuralα7 nicotinic acetylcholine receptor (nAChR) expression and functioning deficits have been extensively associated with cognitive and early sensory gating (SG) impairments in schizophrenia (SCZ) patients and their relatives. SG, the suppression of irrelevant and redundant stimuli, is measured in a conditioning-testing (S1 -S2 ) paradigm eliciting electroencephalography-derived P50 event-related potentials (ERPs), the S2 amplitudes of which are typically suppressed relative to S1 . Despite extensive reports of nicotine-related improvements and several decades of research, an efficient nicotinic treatment has yet to be approved for SCZ...

Research aimed at understanding primary psychotic disorders such as schizophrenia, schizophreniform disorder, and schizoaffective disorder, with electrophysiological methods has flourished over recent years. However, a significant component that is often overlooked or underreported in electrophysiological research of psychosis is the factor of biological sex. Thus, the goal of this systematic review was to summarize the current understanding of EEG sex differences in primary psychotic disorders. Our study found a consistent sex difference relating to the P300 component (male amplitude < females), and that research examining sex differences of ERP waveforms, other than the P300, is very limited with ambiguous findings...

BACKGROUND: Impairments in neurocognition and community functioning are core features of schizophrenia and cognitive training techniques have been developed with the aim of improving these impairments. While cognitive training has produced reliable improvements in neurocognition and functioning, little is known about factors that moderate treatment response. Electroencephalographic (EEG) measures provide a neurophysiological indicator of cognitive functions that may moderate treatment outcomes from cognitive training...

Auditory verbal hallucinations (AVH) are hallmark symptoms of schizophrenia and have been linked to abnormal activation, connectivity and integration within the auditory, language, and memory brain networks. The interhemispheric miscommunication theory of AVH is based on a steadily growing number of studies using a variety of modalities (EEG, fMRI, DTI) reporting that both altered integrity of the interhemispheric auditory pathways and disturbed functional gamma-band synchrony between right and left auditory cortices significantly contribute to abnormal auditory processing and the emergence of AVH...

Little is known about the conscious experience of internal bodily sensations in preschool-aged children. Given that preschoolers are in the most rapid phase of brain development, and display profound emotional development, it was the aim of the present study to establish an adapted interoceptive accuracy paradigm and to investigate associations between sociodemographic (age, sex) and emotional variables with interoceptive accuracy. Forty-nine children (aged 4-6 years) completed the jumping jack paradigm, a heartbeat tracking paradigm, which includes a noninvasive physical perturbation via performing jumping jacks for 10 s...

A study with young and older adults (N = 91) investigated the effect of self-involvement on stereotyping tendency and effort mobilization. We hypothesized that the impact of self-involvement varies as a function of age: increased self-involvement should lead older adults to engage in more effortful information processing and decreased stereotyping, whereas increased self-involvement should have no impact on effort mobilization and stereotyping tendency in younger adults. Young and older adults read narratives under low and high-self-involvement conditions before performing a recognition test that measured their stereotyping tendency...

Our own ongoing motor actions are perceived through sensory feedback pathways, and are integrated with neural processes to modulate further actions. This sensory feedback mechanism is known to contribute to the rehabilitation of impaired motor functions. Recent evidence also suggests that mindfulness meditation improves our awareness to sensation; therefore, enhancement of awareness to sensory feedback through mindfulness meditation training may have potential clinical applications. This study investigated an effect of eight-week practice of mindfulness meditation on speech perception/production processes...

Facial mimicry, the unconscious imitation of others' affective facial expressions, serves as an important basis for interpersonal communication. Although there are many studies dealing with this phenomenon regarding the interaction between adults, only few experiments have explored facial mimicry in response to affective facial expressions of children. In the following study affect-prototypical video clips of children's and adults' faces were presented to 44 adults while the activity of corrugator supercilii and zygomaticus muscles was electromyographically measured...

In a recent event-related potential (ERP) study (Folyi et al., 2016), we have demonstrated that sensory processing of task-irrelevant tones is enhanced when they were previously associated with positive or negative (by the means of monetary gains and losses, respectively) affective meaning relative to tones with neutral meaning, as indexed by the enhancement of the auditory N1-amplitude. In the present study, (1) in line with the hypothesis of affective counter-regulation, we investigated whether positive versus negative tones can receive differential attentional enhancement, depending on motivational context (Experiment 1); and (2) whether the early facilitation of positive and negative tones can operate strictly outside of the focus of voluntary attention (Experiment 2)...

In the era of "big data", we are gaining rich person-specific information about neuroanatomy, neural function, and cognitive functions. However, the optimal ways to create precise approaches to optimize individual function in healthy and disease are unclear. Multimodal analysis and modeling approaches that combine anatomical networks, functional signals, and cognitive neuroscience in single subjects can guide neuromodulation. Our progress could be improved by progressing from statistical fits to mechanistic models...

BACKGROUND: Cognitive deficits and abnormal event-related brain potentials (ERP) have been proposed as risk markers for the development of schizophrenia. Evidence is inconclusive whether these markers indicate a risk for the development of psychosis or illness progression. METHODS: The present study aimed at further clarification by comparing symptom expression (Brief Psychiatric Rating Scale, BRPS), the ERP Mismatch Negativity (MMN), and neuropsychological performance on the MATRICS Consensus Cognitive Battery between healthy controls (HC, n = 38) and individuals at different stages of illness: individuals at risk for psychosis (ARP, n = 33), patients at first admission, thus, early stage (ES, n = 35), chronic schizophrenia patients (CS, n = 25)...
