title: Enhancement of the locomotor response to apomorphine in pertussis toxin-treated animals depends on the site of pertussis toxin injection into the ventral tegmental area.
abstract: The locomotor stimulant response to either systemic or intra-accumbens amphetamine was enhanced 1-2 weeks after pre-treatment with pertussis toxin (PTX) into any of 3 different sites in the ventral tegmental area (VTA). An enhanced response to either systemic or intra-accumbens apomorphine occurred only after pre-treatment into the central VTA. Thus, enhanced sensitivity to drugs of either pre- or post-synaptic elements in the nucleus accumbens may develop depending on the site of the PTX pre-treatment within the VTA.
