Tartalmi leírás:
Implicit sequence learning is a fundamental
mechanism that underlies the acquisition of motor, cog
-
nitive and social skills. The relationship between implicit
learning and executive functions is still debated due to
the overlapping fronto-striatal networks. According to the
framework of competitive neurocognitive networks, dis
-
rupting specific frontal lobe functions, such as executive
functions, increases performance on implicit learning tasks.
The aim of our study was to explore the nature of such a
relationship by investigating the effect of long-term regular
alcohol intake on implicit sequence learning. Since alco
-
hol dependency impairs executive functions, we expected
intact or even better implicit learning in patient group com
-
pared to the healthy controls based on the competitive rela
-
tionship between these neurocognitive networks. To our
knowledge, this is the first study to examine the long-term
effects of alcohol dependency both on implicit learning and
on executive functions requiring different but partly over
-
lapping neurocognitive networks. Here, we show weaker executive functions but intact implicit learning in the alco
-
hol-dependent group compared to the controls. Moreover,
we found negative correlation between these functions in
both groups. Our results confirm the competitive rela
-
tionship between the fronto-striatal networks underlying
implicit sequence learning and executive functions and sug
-
gest that the functional integrity of this relationship is unal
-
tered in the alcohol-dependent group despite the weaker
frontal lobe functions.
