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 ...
Shifting attention to neurons.
(Trends Cogn Sci, 2010-09)
Microcircuits for attention.
(Neuron, 2007-07-05)
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 ...
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 ...
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.
(Science, 2002-05-24)
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 ...
Division of labor in frontal eye field neurons during presaccadic remapping of visual receptive fields.
(J Neurophysiol, 2012-10)
Our percept of visual stability across saccadic eye movements may be mediated by presaccadic
remapping. Just before a saccade, neurons that remap become visually responsive at
a future field (FF), which anticipates the saccade ...
Chaos in percepts?
(Biol Cybern, 1994)
Multistability in perceptual tasks has suggested that the mechanisms underlying our
percepts might be modeled as nonlinear, deterministic systems that exhibit chaotic
behavior. We present evidence supporting this view, obtaining ...
Neuronal correlates of metacognition in primate frontal cortex.
(Neuron, 2012-08-09)
Humans are metacognitive: they monitor and control their cognition. Our hypothesis
was that neuronal correlates of metacognition reside in the same brain areas responsible
for cognition, including frontal cortex. Recent ...
Electrically evoked saccades from the dorsomedial frontal cortex and frontal eye fields: a parametric evaluation reveals differences between areas.
(Exp Brain Res, 1997-12)
Using electrical stimulation to evoke saccades from the dorsomedial frontal cortex
(DMFC) and frontal eye fields (FEF) of rhesus monkeys, parametric tests were conducted
to compare the excitability properties of these regions. ...
