From: Yawning reduces facial temperature in the high-yawning subline of Sprague-Dawley rats

Fig. 5

Average corneal temperature significantly changed around the time of yawning events. a Corneal temperatures were significantly different across the five time points (*P < 0.01). Temperatures significantly decreased during yawning and continued to decrease for 10 s. By 20 s after yawning, temperatures had begun to rise again. b Conchal temperatures were significantly different across the five time points (*P < 0.01). Temperatures increased before yawning, supporting the expression of yawning, and significantly decreased during yawning and the following 10 s. Subsequently they rose back to basal levels. All data points are the mean ± SE of at least 15 thermographic frames
