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 ...
Diminishment of respiratory sinus arrhythmia foreshadows doxorubicin-induced cardiomyopathy.
BACKGROUND: The development of a microcomputer-based device permits quick, simple, and noninvasive quantification of the respiratory sinus arrhythmia (RSA) during quiet breathing. METHODS AND RESULTS: We prospectively and ...
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 ...
EAE cerebrospinal fluid augments in vitro phagocytosis and metabolism of CNS myelin by macrophages.
(J Neurosci Res, 1992-07)
Previous studies from this laboratory have shown that CNS myelin is phagocytized and metabolized by cultured rat macrophages to a much larger extent when myelin is pretreated with serum containing antibodies to ...
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 ...
Express saccades elicited during visual scan in the monkey.
(Vision Res, 1994-08)
Monkeys trained to saccade to visual targets can develop separate "express" and "regular" modes in their distribution of saccadic latencies. The purpose of this study was to determine whether this occurs under more natural ...
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 ...
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. ...
What neural pathways mediate express saccades?
(Behavioral and Brain Sciences, 1993-09)
Induction of anti-myelin antibodies in EAE and their possible role in demyelination.
(J Neurosci Res, 1991-12)
Experimental allergic encephalomyelitis is characterized by invasion of lymphocytes and macrophages into the central nervous system resulting in inflammation, edema, and demyelination. Sera from Lewis rats from 7-95 days ...
