Metabolic responses of the flocculus to optokinetic stimuli as revealed by the [14C]2-deoxyglucose method in pigmented rats.
By means of the [14C]2-deoxyglucose method, metabolic activity in the flocculus during monocular temporonasal optokinetic stimulation was investigated in alert pigmented rats. Local glucose utilization rates of both flocculi were significantly enhanced in the optokinetically stimulated animals. The flocculus ipsilateral to the stimulated eye showed an enhanced local glucose utilization rate as compared with the contralateral flocculus. The most enhanced activity was localized in the middle part of the rostrocaudal extent of the ipsilateral flocculus, and was characterized by its patchy appearance in the granular layer.
