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 ...
A screw microdrive for adjustable chronic unit recording in monkeys.
(J Neurosci Methods, 1998-06-01)
A screw microdrive is described that attaches to the grid system used for recording single neurons from brains of awake behaving monkeys. Multiple screwdrives can be mounted on a grid over a single cranial opening. This ...
Exploring the role of the substantia nigra pars reticulata in eye movements.
Experiments that demonstrated a role for the substantia nigra in eye movements have played an important role in our understanding of the function of the basal ganglia in behavior more broadly. In this review we explore more ...
Shifting attention to neurons.
(Trends Cogn Sci, 2010-09)
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 ...
Corollary discharge circuits in the primate brain.
(Curr Opin Neurobiol, 2008-12)
Movements are necessary to engage the world, but every movement results in sensorimotor ambiguity. Self-movements cause changes to sensory inflow as well as changes in the positions of objects relative to motor effectors ...
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 ...
