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 ... -
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 ... -
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. ... -
Eye fields in the frontal lobes of primates.
(Brain Res Brain Res Rev, 2000-04)Two eye fields have been identified in the frontal lobes of primates: one is situated dorsomedially within the frontal cortex and will be referred to as the eye field within the dorsomedial frontal cortex (DMFC); the other ... -
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 ... -
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 ...
