Fig. 6. Time course of recovery from anesthesia comparing dialysis administration of SPA into the medial pontine reticular formation (mPRF) and cerebellar cortex (cerebellum). Linear regression analysis compared recovery scores from anesthesia after dialysis delivery of 8.8 mm SPA to the cerebellar cortex to recovery scores following mPRF dialysis of 8.8 mm SPA and Ringer's solution (control). Recovery score is expressed on a scale of 0–10 with 10 = full recovery and 0 = no recovery. Each data point represents the mean ± SD of at least three individual recovery scores from different experiments. Linear functions for Ringer's solution and SPA are the same as those shown in figure 3. The linear function for recovery scores following cerebellar administration of SPA revealed a slope of 0.113 and a y-intercept of 5.88.
