In paradigms where participants complete a behavioural task whilst being played a task irrelevant MMN sequence, the elicitation of MMN is found to impact upon the attentional resources required to complete the task, and the degree of this impact is found to be proportional to the size of the MMN Jääskeläinen et al, 1999;Rinne et al, 2006;Roeber et al, 2003;Schröger, 1996).…”

“…This is in contrast to previous studies that have found the amplitude of the CNV to be reduced by acute [144] and chronic [149] alcohol use. Recently, several investigators have attributed enhanced ERP components in abstinent alcoholics to post-withdrawal CNS hyperexcitability [127]. Because it is possible that a similar mechanism may have masked CNV differences between alcoholics and controls in the studies by Olbrich et al [116] and Wagner et al [170], Chao et al [20] examined CNV in active heavy drinkers who were not under treatment for alcoholism.…”

SummaryIntroduction. -Increasing knowledge of the anatomical structures and cellular processes underlying psychiatric disorders may help bridge the gap between clinical signs and basic physiological processes. Accordingly, considerable insight has been gained in recent years into a common psychiatric condition, i.e., chronic alcoholism. Material and methods. -We reviewed various physiological parameters that are altered in chronic alcoholic patients compared to healthy individuals -continuous electroencephalogram, oculomotor measures, cognitive event-related potentials and event-related oscillations -to identify links between these physiological parameters, altered cognitive processes and specific clinical symptoms. Results. -Alcoholic patients display: (1) high beta and theta power in the resting electroencephalogram, suggesting hyperarousal of their central nervous system; (2) abnormalities in smooth pursuit eye movements, in saccadic inhibition during antisaccade tasks, and in prepulse inhibition, suggesting disturbed attention modulation and abnormal patterns of prefrontal activation that may stem from the same prefrontal ''inhibitory'' cortical dysfunction; (3) decreased amplitude for cognitive event-related potentials situated along the continuum of informationprocessing, suggesting that alcoholism is associated with neurophysiological deficits at the level of the sensory cortex and not only disturbances involving associative cortices and limbic structures; and (4) decreased theta, gamma and delta oscillations, suggesting cognitive disinhibition at a functional level. Discussion. -The heterogeneity of alcoholic disorders in terms of symptomatology, course and outcome is the result of various pathophysiological processes that physiological parameters * Corresponding author.
