Table 1 Neuronal damage scores for different brain structures from normothermic control rats and rats in different heat exposure groups.

Treatment	Neuronal damage score (0–3)
	Striatum	Cortex	Hippocampus	Hypothalamus
SED+NT	0 (0, 0.75)	0 (0, 0.5)	0 (0, 0)	0 (0, 0)
3wk1D+NT	0 (0, 1)	0 (0, 0.75)	0 (0, 0.75)	0 (0, 0)
SED+HE	2 (2, 2)*	2 (2, 2)*	2 (2, 2)*	2 (2, 2)*
3wk1D+HE	1 (0, 1)†	1 (0.25, 1)†	1 (0, 1)†	0 (0, 1)†

3wk1D, 1 day after 3‐week exercise training; HE, heat exposure; NT, normothermia; SED, sedentary.

Neuronal damage scores were evaluated by Wilcoxon's signed‐rank test. The data are presented as median values, with the first and third quartiles for the eight rats per group in parentheses.

*p<0.05 compared with SED+NT rats.

†p<0.05 compared with the SED+HE group.
