Dual serotoninergic projections to forebrain in the rat: morphologically distinct 5-HT axon terminals exhibit differential vulnerability to neurotoxic amphetamine derivatives.


The cerebral cortex of the rat and other mammals is innervated by two morphologically distinct classes of serotoninergic (5-HT) axon terminals: fine axons with minute varicosities and beaded axons characterized by large, spherical varicosities. Fine and beaded 5-HT axons exhibit different regional and laminar distributions in forebrain and arise from… (More)
