Neural coding of upshifted, downshifted, and blocked outcomes in the rat (lateral) orbitofrontal cortex
Published on 2015-07-281747 Views
There is much debate over what information about outcomes the orbitofrontal cortex encodes in order to support outcome-guided behavior. One model is that the primary job of neurons there is to distil
