Noudoost, Clark, and Moore deactivated the frontal eye fields (FEF) and recorded from visual cortical area V4.  This disrupted saccades to targets but *increased* pre-saccade activity in V4.  V4 neurons, however, showed reduced discrimination of the target stimulus.  It seems that the FEF provides details about the saccade target to visual cortex.
