Abstract

Event-related oscillations play a key role in understanding the brain dynamics and human information processing. In the present study, the Go/No-Go paradigm has been used to examine whether alcoholics have poor inhibitory control as compared to control subjects in terms of different oscillatory brain responses. The matching pursuit algorithm was used to decompose the event-related electroencephalogram into oscillations of different frequencies. It was found that alcoholics (n=58) showed significant reduction in delta (1.0-3.0 Hz) and theta (3.5-7.0 Hz) power during No-Go trials as compared to controls (n=29). This reduction was prominent at the frontal region. The decreased delta and theta power associated with No-Go processing perhaps suggests a deficient inhibitory control and information-processing mechanism. A neuro-cognitive model has been provided to explain the findings. It is suggested that the oscillatory correlates during cognitive processing can be an endophenotypic marker in alcoholism.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • The finding that inhibition deficits were present in pathological gambling, alcohol dependence and Tourette syndrome is in keeping with experimental studies indicating inhibition deficits in other disorders of behavioural disinhibition.

    “The finding that inhibition deficits were present in PG, AD and TS is in keeping with an abundance of experimental studies indicating that inhibition deficits are present in other disorders of behavioural disinhibition, e.g.ADHD [81], psychopathic and antisocial conditions [82,83], alcohol dependence, [84], cocaine dependence [85] and bulimic eating disorder [86].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
