Abstract
AbstractThe interstitial nucleus of Cajal (INC) in the midbrain reticular formation, which has a reciprocal connection with the vestibular and prepositus nuclei, sends major outputs to the oculomotor and neck motor nuclei. This chapter discusses four major research findings that suggest that the midbrain region within, and in the close vicinity of, the INC is involved in vertical eye position generation in saccades and the vestibulo-ocular reflex (VOR). Involvement of the INC region in the control head posture is reviewed thereafter. Vertical eye position after saccade is not maintained in cats with bilateral lesions in the INC; the vertical VOR is impaired by bilateral lesions of the INC; average discharge rate during vertical saccades is significantly positively correlated with tonic discharge rate; and gain of response of vertical burst-tonic neurons to pitch rotation changes.
