Neural coding of upshifted, downshifted, and blocked outcomes in the rat (lateral) orbitofrontal cortex
Published on Jul 28, 20151741 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
