Subthalamic nucleus principal GABA cellDistal equivalent dendriteSerotonin.One STN regulator is the serotonin (5-HT) system. The STN receives a dense 5-HT innervation. 5-HT1A, 5-HT1B, 5-HT2C, and 5-HT4 receptors are expressed in the STN. 5-HT may regulate the STN via several mechanisms." (Ding S and Zhou FM, 20141 ).
