| Abstract: | The effects of electrical stimulation of the nucleus accumbens (NA) on the activity of neurons of the entopeduncular nucleus (EP) were studied in the rat by extracellular single unit recordings. Many of the EP neurons were identified by antidromic activation from the lateral habenula (HBL). Stimulation of the NA induced inhibitions in 22.7% of the recorded EP cells. The data provide evidence for an inhibitory small projection from the NA to EP. |
