The locomotor effects of nicotine were similarly changed after lesions of the LDTg (Alderson et al. 2005) and, given that the LDTg projects to VTA but not SNC (Oakman et al. 1995), it is likely that in the present experiments it is loss of VTA innervation by pPPTg that is critical.

Bilateral lesions of the TM, which decreased the histamine levels in the VTA and NAc, potentiated the development of CPP induced by morphine (1 mg/kg, a dose that produced no appreciable effect when given alone) and increased the DOPAC/DA ratios in the VTA and NAc, but did not change the glutamate or GABA levels in these nuclei.
