  • Title: Behavior of reticular, vestibular and prepositus neurons terminating in the abducens nucleus of the alert cat.
    Author: Escudero M, Delgado-García JM.
    Journal: Exp Brain Res; 1988; 71(1):218-22. PubMed ID: 3416954.
    Abstract:
    The activity of pontomedullary reticular, vestibular, and prepositus neurons has been recorded in the alert cat during spontaneous and vestibular-induced eye movements. Neurons were identified by their antidromic activation from the abducens nucleus. Spikes of these neurons were used to trigger the recording of field potentials in the abducens nucleus. The analysis by post-spike averaging of the field potentials showed the presence of a trifold system of reciprocal (excitatory and inhibitory) direct projections that originated in the above nuclei and terminated in the abducens nucleus with a distinctly graded effectiveness. This trifold afferent system is involved in the generation of fast eye movements, slow compensatory movements of vestibular origin, and eye fixation, respectively.
