[Compensatory processes after unilateral cutting of the brachia of the posterior colliculi in cats].
The ability for spatial analysis of stimuli of various sensory modalities was studied in cats with a unilateral section of the brachia of the posterior colliculi. To study the possible mechanisms of compensation of localization function in different periods following the brachia section, cortical evoked potentials to sound and light were recorded, and various areas of the neocortex removed (the temporal, parietal or sensorimotor). It was suggested that after a unilateral section of the brachia, compensation of localization of non-acoustic stimuli is linked with the recovery of interhemispheric functional symmetry within the corresponding analyser systems; localization of sound stimuli is restored primarily due to activation of the temporal neocortex in the intact hemisphere, i.e. involvement of one-hemisphere binaural mechanism.
