Encyclopedia > Frontal eye fields

Frontal eye fields are areas in the frontal lobe of the primate brain that play a role in visually guided eye movements[1]. This article or section contains information that has not been verified and thus might not be reliable. ... The frontal lobe is an area in the brain of vertebrates. ... Comparative brain sizes In animals, the brain, or encephalon (Greek for in the head), is the control center of the central nervous system. ... Eye movements are the voluntary or involuntary movements of the eye. ...

Now you see it: frontal eye field responses to invisible targets - Nature Neuroscience (1663 words)
Neurons in the frontal eye field respond even when a visual target is perceptually masked, but small variations in their activity predicts whether a monkey will respond to the stimulus.
One possible caveat is that FEF neurons are also active during eye movements, and the monkeys signaled their perception with an eye movement, so that the slightly larger responses on target-perceived trials might be more related to dumb motor function than to decision-making.
Thus the tight correlation between the size of the target response in the FEF and perception, coupled with the importance of the FEF for eye movements, suggests that the FEF may be critically involved in deciding whether to move the eyes.
