Figure 1.
Body temperatures: Mean ± SEM body temperature recordings from subcutaneously implanted temperature transponders in rats treated with Saline, MA, AMPH, MDMA, or FEN every 2 h. The arrows denote times when drug injections were delivered. Average ambient temperature during treatment was 23.1°C. Asterisks on brackets indicate significant differences for the designated drug groups throughout the designated range. Group sizes: Saline = 21, MA10 = 21, MA12.5 = 18, AMPH = 16, MDMA = 21, FEN = 21. *P< 0.05 or less.
