• following administration of 120 mg/kg modafinil, mice exhibit a lower wakefulness response intensity than in wild-type mice
• following administration of 120 mg/kg modafinil, sleep wave sleep and paradoxical sleep are less significantly altered that in wild-type mice
• mice recover normal sleeping patterns more quickly than wild-type mice following treatment with modafinil
• high doses of modafinil are less effective in inducing wakefulness than low doses unlike in wild-type mice
• mice exhibit a longer duration of paradoxical sleep compared to wild-type mice
• mice exhibit decreased wakefulness duration with an increase in sleep wave sleep duration during the first hour and the first 4 hours of the recovery period compared to wild-type mice
• however, mice do not exhibit a change in the amount of time spent sleeping
