| Outline of Final Research Achievements |
Orexin and MCH are hormone that increase appetite. The insular cortex (IC) expresses these receptors. However almost no information is about the functional roles of these hormones in the IC. To explore this, I performed multiple whole-cell patch clamp recording in the rat IC slice preparation.Orexin A increased the amplitude of unitary inhibitory postsynaptic current (uIPSC) in fast-spiking neuron (FS) to pyramidal cell (Pyr) connections. Same as orexin A, I found that the amplitude of uIPSC in FS to Pyr was increased by orexin B. Pre-application of SB334867 that orexin receptor 1 antagonist diminished the orexin A/B-induced facilitation of uIPSC.
These result suggest orexin is likly to play a role in suppression of gustatory information processing in the IC.
