Summary
The influence of attention on visual cortical neurons
has been described in terms of its effect on the struc-
ture of receptive fields (RFs), where multiple stimuli
compete to drive neural responses and ultimately be-
havior. We stimulated the frontal eye field (FEF) of pas-
sively fixating monkeys and produced changes in V4
responses similar to known effects of voluntary atten-
tion. Subthreshold FEF stimulation enhanced visual
