Plasma parameters

Plasma glucose	CTL	GSD	MOD
mean ± SEM (mM)	9.5 ± 0.3	10.1 ± 0.3	10 ± 0.3
Plasma corticosterone
mean ± SEM (pg/mL)	44.8 ± 3.9	94.5 ± 9.9 (**)	41 ± 4.6

Plasma levels of (A) glucose and (B) corticosterone, measured at the end of the sleep deprivation period. CTL: undisturbed animals (n = 9); GSD: sleep deprived animals by “gentle sleep deprivation” method (n = 9 for glucose determination and n = 8 for corticosterone determination) and MOD: sleep deprived animals by administration of modafinil (n = 9).

^**P < 0.01 for CTL vs GSD, Dunnett t-test after significance in a one-way ANOVA.
