Indole concentrations in (a) hippocampus, (b) cortex and (c) striatum and (d) density of ³H-paroxetine labelled 5-HT uptake sites in cortex 7 days following saline or haloperidol (Hal, 2 mg kg⁻¹ i.p.) 5 min before and 55 min after saline or MDMA (15 mg kg⁻¹ i.p.). The MDMA+haloperidol group was kept at high ambient temperature during the 6 h after the first haloperidol injection. Results shown as means±s.e.mean, n=4–6. Different from saline-treated: ^*P<0.05, ^**P<0.01. Different from MDMA-treated: ΔP<0.05.
