The anterior cingulate cortex (ACC) is a critical component of the human mediofrontal neural circuit that monitors ongoing processing in the cognitive system for signs of erroneous outcomes. Here, we show that the consumption of alcohol in moderate doses induces a significant deterioration of the ability to detect the activation of erroneous responses as(More)
Twelve subjects were tested using a 3-tone auditory oddball paradigm consisting of a standard 1000 Hz tone (P = 80%) and two deviants, namely, a 1200 Hz tone and a 2000 Hz tone (both P = 10%). Testing took place in 3 conditions: (1) attend, in which the subject had to count one of the deviant tones; (2) ignore, in which the subject read a book; and (3)(More)
The present study focused on event-related potentials to tones in the presence and absence of sleep spindles. Six undergraduates were studied throughout an experimental night, following an adaptation session. The event-related potentials to tone stimuli were averaged for each subject. Separate averages were determined for trials on which no sleep spindle(More)
Auditory event-related potentials (ERPs) were recorded from 7 subjects who slept for a single night in the laboratory. An 'oddball' sequence of brief tone pips, differing in intensity, was used. Frequently occurring 70 dB 'standards' were presented with infrequent 80 dB intensity increment deviants and 60 dB intensity decrement deviants. The probability of(More)
The present study investigated event-related brain potential (ERP) reflections of stimulus deviance detection and error monitoring recorded during a go/no-go auditory oddball task. The mismatch negativity and error negativity were analysed as indices of these processes, respectively. We examined whether errors of commission occurred because of failures to(More)
The present experiment investigated the trial-by-trial habituation in the event-related potential (ERP) and the skin conductance response (SCR) to repeated stimuli and dishabituation to rare stimuli. In a balanced design, two groups of subjects passively observed either large black discs as repeated stimuli and small as rare, or vice versa. No consistent(More)
The present report concerns the first study in which electrooculographic (EOG) contamination of electroencephalographic (EEG) recordings in rapid eye movement (REM) sleep is systematically investigated. Contamination of REM sleep EEG recordings in six subjects was evaluated in the frequency domain. REM-active and REM-quiet series were obtained for each(More)
An acoustic matching experiment was conducted consisting of three quasirandom conditions in which the sequence of tones comprising the second stimulus was changed at the beginning, at the end, or not at all. Latency of maximum positivity (P3b) was measured for each subject between Pz and the averaged mastoids. Evaluation of mismatch conditions demonstrated(More)
Dit artikel bespreekt de effecten van blootstelling aan spoorconcentraties lachgas en hogere concentraties op taakuitvoering en op het eeg en Event Related Potentials in het laboratorium. Bovendien worden effecten van acute, cumulatieve en chronische blootstelling op de werkplek besproken. De aandacht richt zich op een serieel model van informatieverwerking(More)
