Neuronal correlates of visual time perception at brief timescales.
(Proc Natl Acad Sci U S A, 2013-01-22)
Successful interaction with the world depends on accurate perception of the timing of external events. Neurons at early stages of the primate visual system represent time-varying stimuli with high precision. However, it ...
The spatial relationship between scanning saccades and express saccades.
(Vision Res, 1997-10)
When monkeys interrupt their saccadic scanning of a visual scene to look at a suddenly appearing target, saccades to the target are made after an "express" latency or after a longer "regular" latency. The purpose of this ...
Frontal eye field neurons orthodromically activated from the superior colliculus.
(J Neurophysiol, 1998-12)
Frontal eye field neurons orthodromically activated from the superior colliculus. J. Neurophysiol. 80: 3331-3333, 1998. Anatomical studies have shown that the frontal eye field (FEF) and superior colliculus (SC) of monkeys ...
Reversible inactivation of macaque frontal eye field.
(Exp Brain Res, 1997-09)
The macaque frontal eye field (FEF) is involved in the generation of saccadic eye movements and fixations. To better understand the role of the FEF, we reversibly inactivated a portion of it while a monkey made saccades ...
Visual perception and corollary discharge.
Perception depends not only on sensory input but also on the state of the brain receiving that input. A classic example is perception of a stable visual world in spite of the saccadic eye movements that shift the images ...
Brain circuits for the internal monitoring of movements.
(Annu Rev Neurosci, 2008)
Each movement we make activates our own sensory receptors, thus causing a problem for the brain: the spurious, movement-related sensations must be discriminated from the sensory inputs that really matter, those representing ...
Compensatory saccades made to remembered targets following orbital displacement by electrically stimulating the dorsomedial frontal cortex or frontal eye fields of primates.
(Brain Res, 1996-07-15)
If the eye-position signal during visually-evoked saccades is dependent on the dorsomedial frontal cortex (DMFC), one would expect that saccades generated to briefly presented visual targets would be disrupted after displacement ...
Association between cell-mediated demyelination and astrocyte stimulation.
(Prog Brain Res, 1992)
Frontal eye field neurons with spatial representations predicted by their subcortical input.
(J Neurosci, 2009-04-22)
The frontal eye field (FEF) is a cortical structure involved in cognitive aspects of eye movement control. Neurons in the FEF, as in most of cerebral cortex, primarily represent contralateral space. They fire for visual ...
Multielectrode evidence for spreading activity across the superior colliculus movement map.
(J Neurophysiol, 2000-07)
The monkey superior colliculus (SC) has maps for both visual input and movement output in the superficial and intermediate layers, respectively, and activity on these maps is generally related to visual stimuli only in one ...
