| Outline of Final Research Achievements |
We have researched to clarify neuronal activity and electrophysiological characteristics, diurnal variation of AVP (arginine vasopressin) neurons, VIP (vasoactive intestinal peptide) neurons in the circadian clock / suprachiasmatic nucleus (SCN) by using the brain slice of normal mouse and neuron type specific mutant mouse. In this research project, we found that the GABA receptor is involved in the diurnal variation of neural activity in SCN. In addition, the change in neuronal activity by the responsiveness of GABA receptor was different depending on each neuron.
