hippocampus
Neuronal pathways, classical neurotransmitters and neuropeptides involved in the hippocampus in major depression. 5-HT: serotonin; Ach: acetylcholine; DA: dopamine; GABA: gamma-aminobutyric acid; Gal: Galanin; Glu: glutamate; NPY: neuropeptide Y; SP: substance P; 5-HT2A: the 5-HT2A subreceptor of the serotonergic receptor; 5-HT7: the 5-HT7 subreceptor of the serotonergic receptor; alpha4 beta2 nAch: the alpha4 beta2 nAch receptor of the nicotinic cholinergic subreceptor; D2: the D2 subreceptor of the dopaminergic receptor; GABAA: the GABAA subreceptor of the GABAergic receptor; Gal2: the Gal2 subreceptor of the galanin receptor; NK1: the NK1 subreceptor of the tachykinin receptor; NMDA: the N-methyl-D-aspartate subreceptor of the ionotropic glutaminergic receptor; NPY1: the NPY1 subreceptor of the neuropeptide Y receptor; A plus mark indicates a postsynaptic excitatory impulse; a minus mark indicates a presynaptic inhibitory impulse.
