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 ...
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 ...
Neuronal adaptation caused by sequential visual stimulation in the frontal eye field.
(J Neurophysiol, 2008-10)
Images on the retina can change drastically in only a few milliseconds. A robust description
of visual temporal processing is therefore necessary to understand visual analysis
in the real world. To this end, we studied subsecond ...
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 ...
Express averaging saccades in monkeys.
(Vision Res, 1999)
When monkeys are presented simultaneously with multiple stimuli, they can make one
of two types of response. Either they make averaging saccades, that land at intermediate
locations between the targets, or target-directed ...
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 ...
