a Recovery time tr (in units of day), i.e., days of treatment required for recovery from the circadian instability caused by orexinergic imbalance, versus treatment timing t0, for two values of ν mo . Interpolation has been used to produce a smooth curve. b Phase diagram on the Itr- ν mo plane, for morning treatment (t0=7 am) and afternoon treatment (t0=3 pm). Above the curves, recovery occurs
