Differential vulnerability of locus coeruleus and dorsal raphe neurons to chronic methamphetamine-induced degeneration

Autor: Yijuan Du, Sanghoon Choi, Alexander Pilski, Steven M. Graves

Publikováno v: Frontiers in Cellular Neuroscience, Vol 16 (2022)

Methamphetamine (meth) increases monoamine oxidase (MAO)-dependent mitochondrial stress in axons of substantia nigra pars compacta (SNc), and ventral tegmental area (VTA) dopamine neurons. Chronic administration of meth results in SNc degeneration an
