“…Galanin expression in locus coeruleus appears to be regulated by estrogen levels (Tseng, Kolb, Raskind, & Miller, 1997) and by nerve growth factor in the basal forebrain (Planas, Kolb, Raskind, & Miller, 1997). Galanin and gamma-aminobutyric acid (GABA)-containing neurons in the rat basal forebrain showed very different distribution patterns (Schober, Brauer, Johansson, Luppa, & Schober, 1990), although an action of galanin on septal cholinergic neurons has been proposed to be mediated by GalR1 receptors on GABA cells (Elvander et al, 2004).…”
