| Abstract(in English) | Recently, Spike-timing Dependent Synaptic Plasticity (STDP) was reported, which is that the relative timing between the pre- and post-synaptic spiking determined the direction and extent of synaptic change by critical temporal window. It shows an importance of the relation between the back-propagated action potential (BAP) and EPSP for the information processing of a dendrite. To investigate how the excitatory postsynaptic inputs of the proximal dendrite effect the information processing of synaptic inputs at the distal dendrite, stimulation was applied to induce BAP and EPSP at the alveus and the proximal dendrite, respectively. The resulting coincidence of magnitude of BAP and EPSP at the distal dendrite was enhanced when the BAP was delivered at a timing to induce LTP. Furthermore, the magnitude of BAP at the distal dendrite was attenuated by the input from the proximal dendrite at a timing (20msec) to induce LTD. These results suggest that the magnitude of BAP delivered to the distal dendrite can be amplified or attenuated depending on the relative timing between proximal input and BAP. This may be due to an effect on the coding process at the distal dendrite and could support the basis for a novel learning rule in the brain. |
