Relationship between the striatal regulation of the temporal organization of behavior and the state of beta-adrenergic mechanisms.

Bilateral damage to the corpus striatum in rats was accompanied by changes in the rhythmic structure of swimming and the dynamics of daily movement activity. Dorsal, but not ventral striatectomy, reversed the effects of the beta-adrenoblocker propranolol on the temporal organization of behavior in the animals. It is likely that the dorsal striatum is extensively dependent on the state of beta-adrenergic innervation.
