Single-unit activity in the primate nucleus reticularis tegmenti pontis related to vergence and ocular accommodation.
1. In the present study we used single-unit recording techniques in alert rhesus monkeys to investigate a precerebellar nucleus, the nucleus reticularis tegmenti pontis (NRTP), for neurons related to vergence and ocular accommodation. 2. In the medial NRTP, we identified 32 cells with activity that linearly increased with increases in the amplitude of the near response and 33 cells with activit...
متن کاملEffect 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 کاملGaze pursuit responses in nucleus reticularis tegmenti pontis of head-unrestrained macaques.
Eye-head gaze pursuit-related activity was recorded in rostral portions of the nucleus reticularis tegmenti pontis (rNRTP) in alert macaques. The head was unrestrained in the horizontal plane, and macaques were trained to pursue a moving target either with their head, with the eyes stationary in the orbits, or with their eyes, with their head voluntarily held stationary in space. Head-pursuit-r...
