Left: successive 5-min, group average core temperature (Tc) values of chronic decerebrate (CD; ○) and pair-fed intact (▪) rats during the 2.5-h precold exposure room temperature baseline period, the 6-h cold exposure, and the postcold period. SEs are denoted with light gray vertical lines. Right: group average temperature for 2-h intervals (one interval in the precold exposure room temperature baseline period, three successive intervals during cold exposure period, and one postcold return to room temperature interval). A: 4°C condition; B: 8°C condition; C: 12°C condition. Different lowercase letters above the histograms on right indicate instances of statistically significant differences (e.g., b denotes significant differences from a). Common letters indicate no significant difference (e.g., bc is not different from b but differs from a).
