| Outline of Final Research Achievements |
M1-muscarinic acetylcholine receptors (mAChRs) exist not only on cell surface but also at intracellular sites in the cerebral cortex and hippocampus. ACh acts on surface and intracellular mAChRs and activates distinct signaling pathways, involving in cholinergic facilitation of long-term potentiation in hippocampus. Stress selectively inhibits the expression of intracellular M1-mAChRs in cerebral cortez and hippocampus, probably leading the redunction of higher brain functions. The present results suggest cholinergic dual transmission in central nervous system and may give a significant clue to explore higher brain functions.
