There are very few acoustic studies reflecting on the localization of speech function within the different loci of the cerebellum. Task based performance profile of subjects with lesion in different cerebellar loci is not reported. Also, the findings on nonfocal cerebellar lesions cannot be generalized to lesions restricted to the cerebellum. Hence, this study was undertaken to reflect upon the differential performance if any of subjects with lesions in different cerebellar loci based on phonatory and diadochokinetic (DDK) tasks. The aims and objectives of this study were to see the pattern of phonatory and DDK measures in dysarthria due to lesions in different cerebellar loci. The study aimed to see if there is a task based localization of speech within the cerebellum. Findings and implications of this study are discussed. (Contains 4 tables and 8 graphs.)
