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 ...
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 ...
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. ...
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 ...
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 ...
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 ...
