incapability in face perception and recognition is one of the main issues in autism spectrum disorders (asd). event related potential (erp) studies have revealed controversial insights on autistic brain responses to faces and objects. the current investigation examined the erp components of young children with asd compared to a typically developing (td) group when looking at the upright and inv...

background and aim: auditory p300 is an event-related potential. cognitive factors like attention are involved in the generation of p300. it seems that normative variation of p300 is necessary for clinical purposes. thus, the current study was designed to establish preliminary normative variation of p300 amplitude and latency at fz and cz sites in adults. methods: this cross-sectional study was...

background and aim: foundations and mechanisms of auditory scene analysis (asa) including segregation and integration were especially reviewed in the study. i focused on the related studies using event-related potentials (erps). recent findings: publications on asa using erps from 1971 to 2014 indicate neural mechanisms of asa in central auditory system. conclusion: asa results in recognition o...

objective: the aim of this study was to investigate the effectiveness of neurofeedback therapy on event-related potential (epr) at both behavioral and physiological level in children (7-12 years) with attention deficit/hyperactivity disorder (adhd).  methods: the current study is a quasi-experimental project whit pre-test and post-test control group. in this study, the subjects (12 patients in ...

a b s t r a c t introduction: in an oddball experiment, the context in which novel stimuli are presented affects characteristics of novelty p3, i.e. as long as there is a difficult task in which the difference between standard and target stimuli is small, recurrent presentation of a highly discrepant stimulus can lead to p300 highly similar to novelty p3. effect of stimulus properties on p300 h...

In daily activities, humans must attend and respond to a range of important items and inhibit and not respond to unimportant distractions. Our current understanding of these processes is largely based on perceptually simple stimuli. This study investigates the interaction of conceptual-semantic categorization and inhibitory processing using Event Related Potentials (ERPs). Participants complete...

11 Electroencephalography is one of the most popular psychophysiological methods in clinical and 12 preclinical research and provides a recording that reflects the global electrical activity of the 13 brain – the EEG. A limitation of the EEG is that it represents the summation of all the electrical 14 activity at a given moment in time, making it difficult to isolate the activity associated wit...

Electromagnetic activity is generated by neurons in the cerebral cortex and subcortical structures of the brain. Neurons generally differ from other cell types of the body by being specialized for the reception, integration, and conduction of excited states. The shape of the neuron is related to its specialized function. Two types of branching extension of the cell body, the dendrite and the ax...
