We examined the effects of cocaine dependence and cocaine and alcohol codependence on the P3A event-related potential component. Ten chronic cocaine-dependent subjects, 10 chronic cocaine and alcohol codependent subjects, and 20 controls were studied

HIV+ subjects have shown impairment on tests of executive function including automatic attention and verbal tasks. Impairment of semantic priming in HIV patients would suggest a disruption of automatic semantic activation. We examined semantic primin

The auditory P50 evoked response to click stimuli was recorded from 10 2-week abstinent African-American chronic cocaine abusers and 10 African-American non-substance-abusing controls. Stimuli consisted of pairs of clicks with a 500-msec interval bet

To examine the degree to which P3A latency was sensitive to the early and progressive effects of human immunodeficiency virus (HIV) disease on frontal cortex function by studying HIV-positive subjects who varied in degree of cognitive impairment.Even

Significant central nervous system toxicity in frontal brain regions has been demonstrated with chronic alcohol consumption both on autopsy and using neuropsychological testing. This study examined the latency of an objective and reproducible brain e

Recent findings of missing or markedly attenuated P50 (or P1) auditory ERPs in Alzheimer's disease (AD) patients suggest this may be a useful diagnostic and/or prognostic marker of AD cholinergic deficits. Those studies used repetitive 1/sec clicks.

Auditory evoked potentials (EP) to high or moderate intensity, single or paired clicks were recorded from normal young adult subjects. A choice-reaction-time paradigm had two sets of instructions, for intensity discrimination and for number (single v

Coherence computed from common reference montages inextricably confounds true coherence with power and phase at the recording and reference electrodes. Direct measurement of coherence requires reference-free EEG data, such as data from EEG scalp curr
