The neuronal circuit of the hippocampus in our brain comprises excitatory and inhibitory synapses, which is related with learning, memory and other high functions in central nervous system. Besides, electrical stimulation has been applied clinically to treat brain disease, such as Parkinson's disease. Therefore, it is of great significance that investigation on the mechanism of excitatory and inhibitory circuit response to electrical stimulation in hippocampus. It could help revealing the mechanism of advan...
