While you were sleeping

Article Abstract:

Scientists believe that sleep helps in strengthening the procedural learning, but now they are even able to reveal the specific patterns of the brain activity that are involved in procedural learning. Researchers are focusing on determining the relationship between rapid eye movement (REM) and procedural learning, but the evidence that links REM and procedural learning is contradictory and confusing.

Reduced sleep in Drosophila shaker mutants

Article Abstract:

Mutagenesis in 'Drosophila melanogaster' is performed as flies also sleep for many hours and, when sleep deprived, show sleep rebound and performance impairments. For this purpose 9,000 mutant lines are screened, thus leading to minisleep (mns), a line that sleeps for one-third of the wild-type amount.

Local sleep and learning

Article Abstract:

Slow wave activity (SWA) improves the ability of a person to perform a task that was learnt before going to sleep. This indicates that SWA homeostasis is related to cellular processes underlying learning rather than to metabolic fatigue or depletion.
