The effects of passive eye rotation on unit discharge in the superior colliculus has been examined in the chloralose anaesthetized cat and brief-burst discharges occurred as the eye traversed a fixed point.
Abstract
The effects of passive eye rotation on unit discharge in the superior colliculus has been examined in the chloralose anaesthetized cat. Providing that velocity exceeded 50 degrees/sec, passive eye movement led to brief-burst discharges in the superior colliculus. This discharge occurred as the eye traversed a fixed point. The displacement of this point from the primary position has been defined as the displacement threshold for that unit. Displacement thresholds range from 3 to 30 degrees and are consistent over a wide range of velocities but become larger at the velocity threshold for the unit. Conduction times to the superior colliculus ranged from 7 to 108 msec.

With the subject exposed to an alternating magnetic field, eye position may be accurately recorded from the voltage generated in a coil of wire embedded in a scleral contact lens worn by the subject.

Extraocular muscle afferent projections to the superior colliculus constitute the single richest projection found in these experiments, and long-latency responses are the most common and dominate in all collicular regions.

This indicates that the stimulation point determines eye position with reference to the cat's head or body, and direction and amplitude of electrically induced saccades change with changing initial eye position to bring the eyes to a constant position.

Watching eye movements in cats with their heads immobilized reveals disjunctive movements are difficult to elicit repeatedly and are generally much slower than the conjugate movements, whose velocity increases with amplitude up to about 300° sec −1.

The spinal pathway of the afferents is mainly in the dorsolateral quadrant contralateral to the recording site and the anatomical characteristics are similar to the lateral funiculus climbing fibrespinocerebellar pathway.

An attempt to review and synthesize the role of these structures in vision on the basis of their anatomy and physiology alone has certain difficulties, and the reader must in large part integrate these data with those contained in other chapters of this volume.

Recordings from the cell bodies of the afferent neurones are described, and an attempt is made to trace these responses to second-order neurones and to discover the change in pattern which occurs at the first synapse.

All the units tested were found to exhibit the movement-direction selectivity with clear-cut phases of excitation and inhibition, whenever nystagmus was present, and in the transitional states between slow-sleep and arousal.

15 Citations1972E Manni, Giovanni Filippo Palmieri +1 more
Unitary responses to moderate manual stretch of individual extraocular muscles were found in some mesodiencephalic areas of the lamb and it seems reasonable to assume that the axons of the second-order neurons of the extraocular muscle proprioception project through the medial lemniscus on the tectum and tegmentum of the mesencephalon and on the posteroventrolateral nuclei of the thalamus.
