Abstract: | By using intracellular technique the authors studied the responses of frog spinal motoneurones and rat dorsal root ganglion evoked by GABA, L-aspartate and dopamine in the presence of 5-hydroxytryptamine and its 1A-agonists or without them. It is shown that buspirone, campirone and serotonin increase the GABA effects but inhibit the effects of aspartate via the GABA- and NMDA-receptors modulation. |
