Effect of pharmacological inactivation of nucleus reticularis tegmenti pontis on saccadic eye movements in the monkey.
The superior colliculus (SC) provides signals for the generation of saccades via a direct pathway to the brain stem burst generator (BG). In addition, it sends saccade-related activity to the BG indirectly through the cerebellum via a relay in the nucleus reticularis tegmenti pontis (NRTP). Lesions of the oculomotor vermis, lobules VIc and VII, and inactivation of the caudal fastigial nucleus, ...
متن کاملRole of monkey nucleus reticularis tegmenti pontis in the stabilization of Listing's plane.
An important problem in motor control is how the nervous system deals with redundant degrees of freedom. It has been well documented that voluntary eye movements are constrained to a plane by Listing's law. Recent evidence has indicated that Listing's law is implemented downstream from the motor superior colliculus (SC), but controversy exists whether this synergy results from a neural control ...
متن کاملDischarge of monkey nucleus reticularis tegmenti pontis (NRTP) neurons changes during saccade adaptation
Saccade accuracy is maintained by adaptive mechanisms that continually modify saccade amplitude to reduce dysmetria. Previous studies suggest that adaptation occurs upstream of the caudal fastigial nucleus (CFN), the output of the oculomotor cerebellar vermis but downstream from the superior colliculus (SC). The nucleus reticularis tegmenti pontis (NRTP) is a major source of afferents to both t...

متن کاملSmooth-pursuit eye-movement-related neuronal activity in macaque nucleus reticularis tegmenti pontis.
Neuronal responses that were observed during smooth-pursuit eye movements were recorded from cells in rostral portions of the nucleus reticularis tegmenti pontis (rNRTP). The responses were categorized as smooth-pursuit eye velocity (78%) or eye acceleration (22%). A separate population of rNRTP cells encoded static eye position. The sensitivity to pursuit eye velocity averaged 0.81 spikes/s pe...
