✦ Synopsis

Short and long lead burst neurons antidromically activated from the rostral mesencephalic reticular formation, and synaptically activated from the contralateral superior colliculus were recorded in the medullary reticular formation underlying the prepositus hypoglossi nucleus. These neurons were shown to be related to vertical eye movements, ranging from pure vertical to oblique planes. Vertical saccade coding was similar to that of horizontal short lead pontine cells. The presence of vertical short and long lead burst neurons in the medullary reticular formation raises new questions about the organization of the control of eye movements in the vertical plane.

This study examines the nature of the efferent projection of omnipause neurons (OPNs) in the midline pontine tegmentum to medium-lead burst neurons (BNs) in the Forel's field H (FFH), both of which exhibit activities related to vertical eye movements, using chronically prepared alert cats.

Recent studies have shown that the interstitial nucleus of Cajal (INC) in the midbrain reticular formation is involved in the conversion of vertical semicircular canal signals into eye position during vertical vestibulo-ocular reflexes. Secondary vestibulo-ocular relay neurons related to the vertica
