Figure 2From: Amygdala opioid receptors mediate the electroacupuncture-induced deterioration of sleep disruptions in epilepsy ratsThe summary of the effects of 100 Hz EA stimulation and pilocarpine in sleep. The bars from the left to the right in each panel represent the data acquired from the baseline, the EA group, the pilocarpine group and the PFS + EA + pilocarpine group. Panels A, B and C represent the percentage of time spent in NREM sleep during the 12-h dark period, the time block between 5-12 h of the dark period, and the 12-h light period, respectively. Panels D, E and F indicate the percentage of time spent in REM sleep during the 12-h dark period, the time block between 5-12 h of the dark period, and the 12-h light period, respectively. **: p < 0.01.Back to article page
