Abstract The commonsense view of religious experience is that it a preconceptual, immediate affective event. Work in philosophy and psychology, however, suggest an attributional cognitive phenomenon. Here the neural correlates are investigated using functional neuroimaging. During recitation, self‐identified subjects activated frontal–parietal circuit, composed dorsolateral prefrontal, dorsomedial frontal medial parietal cortex. Prior studies indicate these areas play profound role...
We investigated if incongruent solutions of simple multiplication problems would elicit similar event‐related brain potentials as inappropriate words in sentences. In Experiment I, 12 subjects verified the appropriateness or final short Both and evoked a phasic negative shift between 300 500 ms having topography. II, we tested with another sample 13 amplitude this arithmetic N400 effect was affected differently by different stimulus onset asynchronies (SOA = 200 ms) errors that were either...
Arithmetic facts are stored in densely interconnected memory networks, and retrieval errors may occur because activation spreads to associated results. We studied the extension of spread by means so-called N400 effect event-related brain potential (ERP). With semantic stimuli, amplitude has proved be inversely proportional amount that originates from a priming context. ERPs were recorded 61 scalp positions while 16 subjects verified 600 multiplication problems ( × b = c). The solution each...
Patients with borderline personality disorder (BPD) and patients social anxiety (SAD) are known to be highly sensitive rejection. Social information processing is assumed play a key role for this shared psychopathological phenomenon. The first steps in encode cues create mental representation of the situation. aim current study was test whether perception participation BPD SAD biased initial stage processing. Focus on P3b, brain potential related stimulus evaluation that has been shown...
Mirror therapy is a to treat patients with pain syndromes or hemiparesis after stroke. However, the underlying neurophysiologic mechanisms are not clearly understood. In order determine effect of mirror-like illusion (MIR) on brain activity using functional near-infrared spectroscopy, 20 healthy right-handed subjects were examined. A MIR was induced by digital horizontal inversion subjects' filmed hand. Optodes placed primary motor cortex (M1) and occipito-parietal (precuneus, PC). Regions...
Social exclusion is a negative experience in social interaction which can be modulated by the perceived eye gaze. In our Cyberball study, we asked how gaze direction – direct versus averted affects processing of using electroencephalogram (EEG) methods. Participants encountered neutral gazes inclusion phase (Block1) and then either or during (Block2). We measured self-reports on Need-Threat Questionnaires (belonging, control, meaningful existence, self-esteem) mood, along with event-related...
Abstract Neuropsychological assessment has to consider the subjective and objective functional deficits of help-seeking individuals in several cognitive domains. Due time constraints clinical practice, web-based approaches have been developed. The current study examined whether mnestic attentive domain can be predicted based on an unsupervised self-administered online neuropsychological screening (NOS): This includes self-reports psychometric memory tests (face-name association, visual...
Patients with Borderline Personality Disorder (BPD) feel ostracized even when they are included. This might be due to a biased processing of social participation in BPD. We examined whether patients BPD also process overinclusion manner, i.e., the degree is increased. An EEG-compatible version Cyberball was used investigate effects inclusion and (33% vs. 45% ball receipt) on perceived ostracism, need threat P3 amplitude, an EEG indicator for expectancy violation. Twenty-nine BPD, 28 Social...
Background: Mirror therapy (MT) was found to improve motor function after stroke.However, there is high variability between patients regarding recovery. Objectives:The following pilot study designed identify potential factors determining this with severe upper limb paresis, receiving MT.Methods: Eleven sub-acute stroke paresis participated, in-patient rehabilitation.After a set of pre-assessments (including measurement brain activity at the primary cortex and precuneus during mirror...
We examined the electrophysiological correlates of processing social exclusion and inclusion by using a modified version Cyberball paradigm. Exclusion was found to be associated with significant increase in P3 complex. The frontal–central P3a primarily related affective rejection, whereas late parietal P3b its perceived intensity. expression negative mood did also depend on earlier experience; affected exclusion, vice versa. In conclusion, our data indicate that complex process rejection can...
Timing in the range of seconds referred to as interval timing is crucial for cognitive operations and conscious time processing. According recent models basal ganglia (BG) oscillatory loops are involved recognition. Parkinsońs disease (PD) a typical that shows distortions timing. Deep brain stimulation (DBS) subthalamic nucleus (STN) powerful treatment PD which modulates motor functions depending on frequency by affecting subcortical-cortical loops. Thus, understanding BG-involvement it...
Recent behavioral and neuroimaging studies have suggested multisensory processing deficits in patients with schizophrenia (SCZ). Thus far, the neural mechanisms underlying these are not well understood. Previous unisensory stimulation shown altered oscillations SCZ. As such, could contribute to aberrant this patient group. To test assumption, we conducted an electroencephalography (EEG) study 15 SCZ control participants whom examined event-related potentials (ERPs) sound-induced flash...
Integrating information across different senses is a central feature of human perception. Previous research suggests that multisensory integration shaped by context-dependent and largely adaptive interplay between stimulus-driven bottom-up top-down endogenous influences. One critical question concerns the extent to which this sensitive amount available cognitive resources. In present study, we investigated influence limited resources on audiovisual measuring high-density...
Social participation can be examined using the Cyberball paradigm, a virtual ball-tossing game. Reducing involvement of participant is supposed to activate neural alarm system, and threaten fundamental social needs. Our previous findings indicate that latter process linked an enhancement centro-parietal P3 amplitude, signalling modulation subjective expectancy involvement. A preceding more frontal ERP component, P2, does not depend probability involvement, but reflects appraisal reward. In...
The affective and cognitive mechanisms elicited by the experience of social exclusion-or ostracism-have recently been explored using behavioral neurocognitive methods. Most studies took advantage Cyberball paradigm, a virtual ball tossing game with presumed co-players connected via internet. Consistent findings indicate that exclusion obviously threatens fundamental needs (belonging, self-esteem, meaningful existence, control) lowers mood. In this study, we followed question whether...
Subjective cognitive complaints (SCC) and their role as a possible indicator for subsequent dementia became of growing interest in recent research. In contrast to studies that focused primarily on memory complaints, we aimed (a) evaluate questionnaire register SCC multiple domains (Complainer Profile Identification, CPI), (b) assess the association between psychosocial variables, (c) whether complainer types can be differentiated. Confirmatory factor analysis construct validity was computed...
The phenomenon of social exclusion can be investigated by using a virtual ball-tossing game called Cyberball. In neuroimaging studies, structures have been identified which are activated during exclusion. But to date the underlying mechanisms not fully disclosed. previous electrophysiological studies it was shown that P3 complex is sensitive manipulations in Cyberball paradigm and there correlation between amplitude self-reported pain. Since this posterior event-related potential (ERP)...
The paradigm of distractor-induced blindness has previously been used to track the transition from unconscious conscious visual processing. In a variation this in study, participants (n = 13) had detect an orientation change tilted bars (target) embedded dynamic random pattern; onset target was signaled by presentation color cue. Occasional changes preceding cue served as distractors and severely impaired target's detection. ERPs showed that frontal negativity cumulatively activated...
