[Compensation of anisocoria in cats following transection of the optic tract: the role of subcortical commissures].

Experiments were carried out on cats with unilateral optic tract transection and cerebral commissures. The data obtained indicate that destruction of the afferent part of the pupillary reflex by optic transection led to reversible anisocoria. In cats with combined transection of the optic tract and teleencephalic, diencephalic and mesencephalic commissures, such a rehabilitation did not occur. In contrast, section of telencephalic commissures alone was immaterial for the processes of compensation of papillary system function. The data obtained attest to an important role of subcortical commissures in compensation of anisocoria after destruction of the afferent arc of the papillary reflex to light.
