Bar graphs showing group results (mean ± SEM) of the effects of vehicle or antipsychotic drugs on intruder-elicited thermoregulatory events. a ¶ After vehicle pre-treatment, the intruder-elicited slope of the BAT (black bar) temperature signal is significantly greater than corresponding slope of the body (white bar) temperature signal (P < 0.05). ns lowest dose intruder-elicited 0–5 min slope of the temperature signals for each drug not significantly different from slope after vehicle, P > 0.05. Asterisks indicate significant linear regression between the log dose of drug and the slopes of the BAT or body temperature signals recorded from the resident rat during the first 5 min after introduction of the intruder rat, **P < 0.01, ***P < 0.001. b ¶¶ After vehicle pre-treatment, the intruder-elicited increase in BAT temperature (black bar) is significantly greater than corresponding increase in body temperature (white bar) (P < 0.01). ns lowest dose intruder-elicited increase in the temperature signal for each drug not significantly different from vehicle P > 0.05. Asterisks indicate significant linear regression between log dose of drug and changes in BAT or body temperature signals recorded from the resident rat 18–28 min after introduction of the intruder rat, *P < 0.05, ***P < 0.001. c ns lowest dose of each drug not significantly different from vehicle tail flow during the first 5 min after introduction of the intruder, P > 0.05. Asterisks indicate significant linear regression between log dose of drug and changes tail artery Doppler flow signal recorded from the resident rat 0–5 min after introduction of the intruder rat, *P < 0.05, **P < 0.01. d Behavioral activity during 0–5 min after introduction of the intruder rat (percent total time). ns lowest dose not significantly different from vehicle activity, P > 0.05. ¶ intruder-elicited activity after lowest dose of chlorpromazine significantly less than activity after vehicle. Asterisks indicate significant linear regression between log dose of drug and behavioral activity recorded from the resident rat 0–5 min after introduction of the intruder rat, *P < 0.05, **P < 0.01
