Prefrontal cortex
and the hierarchical control of behavior
Cognitive control
refers to our ability to internally guide our
thoughts and actions based on plans,
goals, and our current context.
The prefrontal
cortex (PFC) is known to be essential to cognitive
control function. However, the organization of the frontal
cortex
remains a source of considerable
controversy. This talk will
describe
a recent line of research in our
lab that tests the hypothesis that
the PFC may be organized according
to a control hierarchy along its
rostro-caudal axis. Evidence from fMRI and neuropsychological studies
will be presented that test this
hypothesis during action selection
and learning.
