Download "From biophysics to cognition: reward-dependent adaptive choice behavior"
In neurobiological studies of various cognitive abilities,
neuroscientists use mathematical models to fit behavioral data
from well-controlled experiments and look for neural activities
that are correlated with parameters in those models. The
pinpointed neural correlates are often taken as evidence that a
given task is performed according to the prescription of the
applied model, and the relevant brain areas encode parameters
of such a model. However, to go beyond correlations toward
causal understanding, it is necessary to elucidate at multiple
levels the neural circuit mechanisms of cognitive processes.
This review focuses on recent studies of reward-based
decision-making that have begun to tackle this challenge.
