β¦ Synopsis
The afferent and efferent connections of omnipause neurons involved in saccadic eye movements were studied electrophysiologically in ketamine anesthetized cats. Omnipause neurons were identified by their characteristic discharge pattern which was qualitatively unaltered by ketamine anesthesia.

## Abstract The present paper deals with the study of the structure of horizontal neuron chains, one of the aspects of intracortical intraneuronal relationships. The motor cortex (field 4) of cats and lower monkeys (Papio hamadryas and Macacus rhesus s. M. Mullata) was treated by the impregnating m
Studies undertaken in head-restrained animals have long implicated the omnipause neurons (OPNs) in the initiation of saccadic eye movements. These inhibitory neurons discharge tonically but cease firing just before and during saccades in all directions. By recording from OPNs in alert behaving head-
