[Inhibitor interneurons of horizontal ocular saccades studied in the alert cat with the aid of intra-axonal injections of peroxidase].
A simultaneous study of the functional and morphological characteristics of burst inhibitory neurons (B.I.N.) has been performed in the alert cat. For the first time, in the central nervous system of mammal, extra- and intracellular records have been coupled with intra-axonal injection of H.R.P. in the alert animal. The B.I.N. discharge during saccades and the quick phase of vestibular and optokinetic nystagmus oriented toward the ipsilateral side of recording. The frequency of discharges is proportional to the eye angular velocity. The axons end on the abducens motoneuron. Collaterals reach the controlateral prepositus hypoglossi nucleus, medial vestibular nucleus and reticular nuclei.
