BGC20-761, a novel tryptamine analog, enhances memory consolidation and reverses scopolamine-induced memory deficit in social and visuospatial memory tasks through a 5-HT6 receptor-mediated mechanism.

abstract：:Substance P, administered intrathecally in the lumbar area of paraplegic rats activated the electromyogram (EMG) of the hindlimbs. This effect was markedly enhanced by previous denervation by 5,7-dihydroxytryptamine. Stimulation of the motoneurons by substance P was followed by a blunted response to the excitatory sub...
