“…Continued structural analysis, using double immunolabeling receptor and immunohistochemistry or transmitter histochemistry together with receptor autoradiography, has given evidence for the frequent existence of long-distance transmitter/receptor mismatches (topological mismatches) in the monoamine and peptide systems (see Herkenham, 1987;Fuxe et al, 1988bFuxe et al, , 2003bZoli et al, 1989;Bunnemann et al, 1991;Ferré et al, 1996;Jansson et al, 1998Jansson et al, , 1999Jansson et al, , 2001Jansson et al, , 2002Schwartz et al, 1998;Caberlotto et al, 1998;Fuxe et al, 2005;Jacobsen et al, 2006). Such observations strongly indicate the existence of long-distance VT in the brain.…”
