Figure 2. ASF and CSF experiments—serum corticosterone concentration.

Figure 2

Effects of acute sleep fragmentation (ASF, Fig. 4A) and chronic sleep fragmentation (CSF, Fig. 4B), adrenergic blockade (phentolamine (Phe) or propranolol (Pro) or vehicle (Veh), and their interaction on serum corticosterone levels. Sample sizes of each treatment group are listed with their respective bar graph and were analyzed using a two-way ANOVA and Tukey’s HSD post hoc tests. Data shown as means 1 SE for each group and differing letters denotes p < 0.05.
