Research Abstract

We discovered that the part of the prefrontal cortex of primates is activated when the subjects were required to select the action under the presence of multiple rules, but inactivated when only a single rule is present. Such a context dependent activation and inactivation of a particular brain region suggests that the so-called functional map of brain is not hard-wired, but rather it undergoes flexible reorganization when necessary. Our findings may require the revision of the conventional notion of the fixed functional map of brain.
