Preparatory processes in a case of hemi-parkinsonism.
Reaction times and movement times were recorded in a subject with parkinsonian symptoms confined largely to the left side of the body. Advance information concerning the movement was varied, being with complete, partial or no preparation. The results suggest that processing of preparation for the movement is not qualitatively different for the more affected side, but is substantially slowed.
