An event related potentials (ERPs) imaging system for brain research

1998 IEEE Nuclear Science Symposium Conference Record. 1998 IEEE Nuclear Science Symposium and Medical Imaging Conference (Cat. No.98CH36255), 2002
An event related potentials (ERPs) imaging system was developed for brain research. The system consists of a personal computer based 19 channel EEG recorder, a visual stimulator, an auditory stimulator and a somatosensory stimulator. The response time can be also measured simultaneously.

Performance differences in reaction tasks are reflected in event-related brain potentials (ERPs)

Ergonomics, 1998
Event-related potentials (ERPs), which can be extracted from the electroencephalogram (EEG), are assumed to reflect distinct cognitive processes in real time. Hence ERP analysis could be used in cognitive ergonomics as a tool to specify, for example, bottlenecks or sources of individual performance differences.

Event-related brain potentials (ERPs) in schizophrenia for tonal and phonetic oddball tasks

Biological Psychiatry, 2001
Prior studies using simple target detection ("oddball") tasks with pure tones have reported asymmetric reduction of the P3 event-related potential (ERP). This study investigated the time course and topography of ERPs recorded during both tonal and phonetic oddball tasks.Event-related potentials of 66 patients (14 unmedicated) diagnosed with ...

The novelty P3: an event-related brain potential (ERP) sign of the brain's evaluation of novelty

Neuroscience & Biobehavioral Reviews, 2001
A review of the literature that examines event-related brain potentials (ERPs) and novelty processing reveals that the orienting response engendered by deviant or unexpected events consists of a characteristic ERP pattern, comprised sequentially of the mismatch negativity (MMN) and the novelty P3 or P3a. A wide variety of evidence suggests that the MMN

Effects of aging on event-related brain potentials (ERPs) in a visual detection task

Electroencephalography and Clinical Neurophysiology/Evoked Potentials Section, 1994
Event-related brain potentials (ERPs) were recorded from 74 subjects (45 men) between 18 and 82 years of age in a simple visual detection task. On each trial the subject reported the location of a triangular flash of light presented briefly 20 degrees laterally to the left or right visual field or to both fields simultaneously.

Psychopathy and Event-Related Brain Potentials (ERPs) associated with attention to speech stimuli

Personality and Individual Differences, 1987
Abstract Event-related brain potentials (ERPs) were used to determine whether low left-hemisphere arousal or unusual cortical responses to speech stimuli might be associated with anomalies in language function that reportedly occur when psychopaths perform lateralized information-processing tasks.

Semantic and repetition priming within the attentional blink: An event-related brain potential (ERP) investigation study

Biological Psychology, 2007
An attentional blink (AB) paradigm was used to directly compare semantic and repetition priming for reported words versus missed words. Three target words (T1, T2, T3) were embedded in a rapidly presented stream of non-word distractors for report at the end of each trial. Whereas T1 was not related to either T2 or T3, T2 and T3 could be unrelated words,

Cognitive function by brain event-related potentials (ERP) in elderly with borderline isolated systolic HYPERTENSION (BISH)

Archives of Gerontology and Geriatrics, 2007
Several studies have shown a relationship between BISH and cerebrovascular events, but no studies have investigated a relationship with cognitive function. The aim was to assess the cognitive function in the elderly with recent BISH. According to WHO Guidelines (1999), we selected 10 elderly normotensives, 10 elderly with recently diagnosed (

Context effects in a category verification task as assessed by event-related brain potential (ERP) measures

Biological Psychology, 1998
This study examined the extent to which decisions about category membership (between category structure) are dependent on or dissociable from the typically structure (within category structure) of categories. To this end, behavioral and event-related brain potential (ERP) measurements were obtained in a category verification task that incorporated a ...

Assessment of working memory abilities using an event-related brain potential (ERP)-compatible digit span backward task

Clinical Neurophysiology, 2005
This study investigated the effectiveness of an ERP-compatible Digit Span Backward (ERP-DB) task to determine working memory abilities in healthy participants.Participants were administered both the standard digit span backward and ERP-DB tasks. The ERP-DB task was divided into two sections, consisting of 2, 4, 6 and 8 (Group 1) and 3, 5, and 7 (Group ...
