Figure 1: Brain galanin pathways Galaninergic projections (green lines) and neurotransmitter co-localisation with galanin (***) in the rat brain. Dopaminergic projections (red lines) to structures of the mesolimbic dopamine system. [Brain template taken from 57]. 5-HT, serotonin; ACh, acetylcholine; ADH, antidiuretic hormone; AMG, amygdala; Arc, arcuate hypothalamic nucleus; Cb, cerebellum; CPu, caudate putamen (striatum); DA, dopamine; GABA, gamma-aminobutyric acid; Glu, glutamate; HIP, hippocampus; HYP, hypothalamus; LC, locus coeruleus; NAc, nucleus accumbens; NA, noradrenaline; PFC, pre-frontal cortex; PVN, paraventricular hypothalamic nucleus; TH, thalamus; VTA, ventral tegmental area.
