abstract：:In rat CA1 hippocampal pyramidal neurons (HPNs), somatostatin (SST) has inhibitory postsynaptic actions, including hyperpolarization of the membrane at rest and augmentation of the K+ M-current. However, the effects of SST on synaptic transmission in this brain region have not been well-characterized. Therefore we use...
