Fig. 7From: Differential role of dose and environment in initiating and intensifying neurotoxicity caused by MDMA in ratsEffects of MDMA doses and environments, respectively, on initiating and intensifying serotonergic injury. SERT density was used to estimate those effects. a Schematic diagram of the medial FCx and corresponding coronal sections used to assess the SERT-containing fiber density (anterior-posterior location + 3.70 relative to bregma). b Changes in SERT-containing fibers. Bar: 100 μm. c The means of optical densities (arbitrary unit). **P < 0.01 vs. CTL, examined with ANOVA followed by post-hoc test. CTL-S, saline as control; HD-H ─, high-dose-induced hypothermia; HD-H+, high-dose-induced hyperthermia; LD-H+, low-dose-induced hyperthermiaBack to article page
