Abstract
Studies about
the neuropsychological aspects of alcohol have increased recently. Researches
investigating the effects of alcohol intoxication are focused on both the
mechanism of action of neurotransmitters and brain regions determined to use
functional magnetic resonance imaging (fMRI). In addition, it is seen that
experimental studies on the psychological effects of alcohol intoxication.
Alcohol intoxication occurs with rising about 100 mg/dl in the blood alcohol
level. The effects of intoxicated have changes in cognitive functioning such as
weakening of attention, response inhibition and changes in behavior like
aggression. Alcohol with the transmission via neurotransmitters in the
prefrontal region indicates that weaken the neuronal activation in these
regions. Therefore, during alcohol intoxication it is seen that decreased
self-regulation and self-control, delayed responding and shifting response
contingencies, impaired executive functioning. Anterior cingulat cortex (ACC)
is known to be activated in alcohol intoxication and it is explained with focused
attention, which is indicated that deteriorating perception and the content of
thought cause arising the focused attention. According to multiple
meta-analyses of experimental researches, alcohol intoxication augments
aggressive behavior reacting when provocation occurs. Findings from researches
on aggression have shown that the medial prefrontal region is activated on
displaced aggression and the dorsal ACC is activated on general aggression.
Within this context could be explained arising general aggresion during the
alcohol intoxication. In the light of all this information although alcohol
intoxication cause cognitive, emotional and behavioral effects; it thought to
be insufficient brain imaging studies on alcohol intoxication consisting of the
whole.
