These results were confirmed using a combination of vesicular glutamate transporter immunoreactions. Collectively, these findings suggest that PV neurons produce fast and reliable inhibition of medium spiny neurons in response to thalamic inputs. In contrast, excitatory inputs from motor cortices modulate PV dendrite excitability, possibly in concert with other glutamatergic, GABAergic, and dopaminergic inputs., application/pdf}, title = {Parvalbumin-producing striatal interneurons received excitatory inputs onto proximal dendrites from motor thalamus in male mice}, year = {}, yomi = {ナカノ, ヤスタケ} }
