| Outline of Final Research Achievements |
We explored the role of the dorsal striatum in interval timing ranging from seconds to minutes. Intra dorsal striatum injection of an NMDA receptor antagonist impaired the acquisition of the memory for temporal duration. Moreover, c-Fos protein expression was enhanced during temporal memory formation in the dorsal striatum. Taken together, these findings suggest that the dorsal striatum plays an important role in the formation of memory for temporal duration.
