Research Abstract |
We established calcium imaging methods from dendrites using a new multi-photon laser microscope. There is the progress of research on the following points using multiple techniques. We confirmed that the reciprocal projection between the primary somatosensory cortex (S1) and the secondary motor cortex (M2) in mouse. We revealed that the input from M2 causes firing of selective layer 5 neurons in the S1, which is following dendritic spikes. From behavioral experiments, which is related with haptic perception in mouse, we found that an inhibition of M2 inputs with the optogenetical methods disturbed the haptic perception. From this study, we have found that the dendritic calcium response is a building block of a basic component of the perception.
