Figure 1

Behavioral response to cold stimuli. Four outcome measures are shown: intake (A), facial contact events (B), licks (reward)/facial contact ratio (measures success) (C), and facial duration/contact (D) for cold temperatures (-4, 2, 10, and 24°C), expressed as a percent of baseline (37°C). + indicates significant increase, and * indicates a significant decrease (P < 0.05). (E) represents the change in the licks/facial contact (success ratio) over the 30-minute test period for each of the temperatures tested.
