“…These suggestions are also consistent with the reported involvement of MAP kinase pathways in the regulation of several neurotransmitter systems (Della Rocca et al, 1999;Greengard, 2001) that have been implicated in the regulation of aggressivity. These include serotonergic (Birger et al, 2003;Davidge et al, 2004;Edwards and Kravitz, 1997;Ferris et al, 1999;Huber et al, 1997;Korte et al, 1996;Manuck et al, 2002;Miczek et al, 2001), dopamine, norepinephrine, GABA, glutamate, acetylcholine, cholecystokinin, substance P, and opioid neurotransmitter systems (Brodkin et al, 2002;Chiavegatto et al, 2001;Olivier et al, 1995;Siegel et al, 1999).…”
