Effect of reversible inactivation of macaque lateral intraparietal area on visual and memory saccades.
Previous studies from our laboratory identified a parietal eye field in the primate lateral intraparietal sulcus, the lateral intraparietal area (area LIP). Here we further explore the role of area LIP in processing saccadic eye movements by observing the effects of reversible inactivation of this area. One to 2 microl of muscimol (8 mg/ml) were injected at locations where saccade-related activ...
متن کاملEffects of reversible inactivation of the dorsomedial hypothalamus on panic- and anxiety-related responses in rats.
The medial hypothalamus is part of a neurobiological substrate controlling defensive behavior. It has been shown that a hypothalamic nucleus, the dorsomedial hypothalamus (DMH), is involved in the regulation of escape, a defensive behavior related to panic attacks. The role played by the DMH in the organization of conditioned fear responses, however, is less clear. In the present study, we inve...
متن کاملInterdependence of Fixations and Saccades
The present study investigates the relation between the reading process and text comprehension during naturalistic text reading. To that end, participants read easy and difficult texts while their eye movements were recorded. After each reading, participants filled-in comprehension questionnaires. We investigated classical measures of the reading process related to comprehension (fixation durat...

Muscimol-induced inactivation of the monkey frontal eye field: effects on visually and memory-guided saccades. Although neurophysiological, anatomic, and imaging evidence suggest that the frontal eye field (FEF) participates in the generation of eye movements, chronic lesions of the FEF in both humans and monkeys appear to cause only minor deficits in visually guided saccade generation. Stronge...
متن کاملThe effects of microstimulation of the dorsomedial frontal cortex on saccade latency.
Neural regions in the dorsomedial frontal cortex (DMFC), including the supplementary eye field (SEF) and the presupplementary motor area (pre-SMA), are likely candidates for generating top-down control of saccade target selection. To investigate this, we applied electrical microstimulation to these structures while saccades were being planned to visual targets. Stimulation administered to super...
