Local aspects of sleep and wakefulness.

摘要: Slow waves, the hallmark of NREM (Non Rapid Eye Movement) sleep, are not uniformly distributed across cortical surface, but can occur locally and asynchronously brain regions. Their regional distribution amplitude is affected by maturation time spent awake, mediated in part experience-dependent changes synaptic strength. Recent studies have shown that local low-frequency oscillations (<10Hz) also REM sleep during wakefulness, leading to region-specific cognitive errors. Local decreases increases slow wave activity posterior regions been linked occurrence dreaming unconscious respectively. Finally, coexistence sleep-like wake-like patterns different areas characteristic several disorders may offer insights into these conditions.
