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 ...
Spatial and temporal scales of neuronal correlation in visual area V4.
(J Neurosci, 2013-03-20)
The spiking activity of nearby cortical neurons is correlated on both short and long time scales. Understanding this shared variability in firing patterns is critical for appreciating the representation of sensory stimuli ...
Reversible inactivation of macaque dorsomedial frontal cortex: effects on saccades and fixations.
(Exp Brain Res, 1999-02)
Neural recording and electrical stimulation results suggest that the dorsomedial frontal cortex (DMFC) of macaque is involved in oculomotor behavior. We reversibly inactivated the DMFC using lidocaine and examined how saccadic ...
Frontal eye field neurons assess visual stability across saccades.
(J Neurosci, 2012-02-22)
The image on the retina may move because the eyes move, or because something in the visual scene moves. The brain is not fooled by this ambiguity. Even as we make saccades, we are able to detect whether visual objects remain ...
Microcircuits for attention.
Researchers who study the neuronal basis of cognition face a paradox. If they extract the brain, its cognitive functions cannot be assessed. On the other hand, the brain's microcircuits are difficult to study in the intact ...
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 ...
Effective spread and timecourse of neural inactivation caused by lidocaine injection in monkey cerebral cortex.
(J Neurosci Methods, 1997-06-06)
We studied the effective spread of lidocaine to inactivate neural tissue in the frontal cortex of the rhesus monkey. Injections of 2% lidocaine at 4 microl/min were made while units were recorded 1 or 2 mm away. To inactivate ...
The feeling of looking.
(Nat Neurosci, 2007-05)
Delay activity of saccade-related neurons in the caudal dentate nucleus of the macaque cerebellum.
(J Neurophysiol, 2013-04)
The caudal dentate nucleus (DN) in lateral cerebellum is connected with two visual/oculomotor areas of the cerebrum: the frontal eye field and lateral intraparietal cortex. Many neurons in frontal eye field and ...
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 ...
