Sleep deprivation differentially impairs cognitive performance in abstinent methylenedioxymethamphetamine ("Ecstasy") users.

2 Nov 2009 Methylenedioxymethamphetamine (MDMA; "Ecstasy") is a popular recreational drug and brain serotonin (5-HT) neurotoxin. Neuroimaging data indicate that some human MDMA users develop persistent deficits in brain 5-HT neuronal markers. Although the ... Read more...

Cortical firing and sleep homeostasis.

22 Sep 2009 The need to sleep grows with the duration of wakefulness and dissipates with time spent asleep, a process called sleep homeostasis. What are the consequences of staying awake on brain cells, and why is sleep needed? Surprisingly, we do not know ... Read more...

The impact of sleep duration and subject intelligence on declarative and motor memory performance: how much is enough?

30 Aug 2009 Recent findings clearly demonstrate that daytime naps impart substantial memory benefits compared with equivalent periods of wakefulness. Using a declarative paired associates task and a procedural motor sequence task, this study examined the effect ... Read more...
