Dopamine does not affect sensory synaptic transmission to giant interneurons. A, Plot of the amplitude of monosynaptic EPSP in a giant interneuron, evoked by stimulation of a dorsal root, showing that the 5-HT1A antagonistS(−)-UH301 did not counteract the 5-HT-mediated reduction of the amplitude of the EPSP. B, The 5-HT1Aantagonist S(−)-UH301 decreased the amplitude of the EPSP, and addition of 5-HT reduced the EPSP further. C, The amplitude of sensory-evoked EPSPs was not affected by dopamine (200 μm; n = 6). D, The amplitude of compound EPSP recorded in a giant interneuron by stimulation of dorsal column is not affected by dopamine.
