Signal transduction by neuronal cell of central nerve system enables human to perform high level of motion, study and memory. On this occasion, locally-cerebral blood flow is known to be neuronal activity-regulated and is closely related to neuron and astrocyte, but the detailed mechanism is still unknown. In this study, we examined the response of neuron and blood vessel at synaptic plasticity in the vicinity when we artificially-induced synaptic plasticity. By inducing synaptic plasticity, we discover that neuron's transmission efficiency is elevated and vessel diameter is coarctated after induced by synaptic plasticity. In conclusion, vessel diameter coarctation suggests that mechanism of memory or study in the cell level depends on synaptic plasticity. (112 words)
