Sleep deprivation induced by the modified multiple platform technique: quantification of sleep loss and recovery
Deep Brain Stimulation Reverses Anhedonic-Like Behavior in a Chronic Model of Depression: Role of Serotonin and Brain Derived Neurotrophic Factor
Resistance to ethanol sensitization is associated with increased NMDA receptor binding in specific brain areas.

Results indicate that specific brain areas may be differentially susceptible to oxidative stress after sleep deprivation and the apparent vulnerability of the hypothalamus to these effects may contribute to the functional effects of sleep deprivation.
Pain hypersensitivity induced by paradoxical sleep deprivation is not due to altered binding to brain μ-opioid receptors
Differential propensity to ethanol sensitization is not associated with altered binding to D1 receptors or dopamine transporters in mouse brain

It is suggested that brain D1 and DAT binding, unlike the recently reported changes in D2 binding, do not differentiate mice that develop behavioral sensitization to ethanol from those that do not.

The results indicate that the multiple platform technique induces a distinct activation of the HPA axis, and that PS deprivation may act as an additional stressor.
Sensitization to ethanol’s stimulant effect is associated with region-specific increases in brain D2 receptor binding

The observed increases in D2-receptor binding in circumscribed targets of nigrostriatal projections may reflect either a pre-existing condition in sensitization-prone animals or a selective vulnerability of D2 receptors to chronic EtOH in these animals, and may be a marker for differential susceptibility to EtOH sensitization.
Paradoxical Sleep Deprivation and Sleep Recovery: Effects on the Hypothalamic–Pituitary–Adrenal Axis Activity, Energy Balance and Body Composition of Rats

Results showed that sleep deprivation produces increased energy expenditure and loss of fat content, and most of the alterations were reversed by sleep recovery, except for corticosterone levels and body composition.
