Composition and topographic organization of signals sent from the frontal eye field to the superior colliculus.
(J Neurophysiol, 2000-04)
The frontal eye field (FEF) and superior colliculus (SC) contribute to saccadic eye movement generation, and much of the FEF's oculomotor influence may be mediated through the SC. The present study examined the composition ...
Signal transformations from cerebral cortex to superior colliculus for the generation of saccades.
(Vision Res, 2001)
The ability of primates to make rapid and accurate saccadic eye movements for exploring the natural world is based on a neuronal system in the brain that has been studied extensively and is known to include multiple brain ...
Single Neurons and Primate Behavior

A corollary discharge for perceptual stability
A pathway in primate brain for internal monitoring of movements.
It is essential to keep track of the movements we make, and one way to do that is to monitor correlates, or corollary discharges, of neuronal movement commands. We hypothesized that a previously identified pathway from brainstem ...
Frontal eye field sends delay activity related to movement, memory, and vision to the superior colliculus.
(J Neurophysiol, 2001-04)
Many neurons within prefrontal cortex exhibit a tonic discharge between visual stimulation and motor response. This delay activity may contribute to movement, memory, and vision. We studied delay activity sent from the frontal ...
What the brain stem tells the frontal cortex. I. Oculomotor signals sent from superior colliculus to frontal eye field via mediodorsal thalamus.
(J Neurophysiol, 2004-03)
Neuronal processing in cerebral cortex and signal transmission from cortex to brain stem have been studied extensively, but little is known about the numerous feedback pathways that ascend from brain stem to cortex. In this ...
The Superior Colliculus and the Cognitive Control of Movement
(The New Cognitive Neurosciences, 2000)
What the brain stem tells the frontal cortex. II. Role of the SC-MD-FEF pathway in corollary discharge.
(J Neurophysiol, 2004-03)
One way we keep track of our movements is by monitoring corollary discharges or internal copies of movement commands. This study tested a hypothesis that the pathway from superior colliculus (SC) to mediodorsal thalamus ...
Influence of the thalamus on spatial visual processing in frontal cortex.
Each of our movements activates our own sensory receptors, and therefore keeping track of self-movement is a necessary part of analysing sensory input. One way in which the brain keeps track of self-movement is by monitoring ...
