Sleep Deprivation Impairs the Accurate Recognition of Human EmotionsNCBI

Investigate the impact of sleep deprivation on the ability to recognize the intensity of human facial emotions.

REM Sleep Depotentiates Amygdala Activity to Previous Emotional ExperiencesCurrent Biology

Clinical evidence suggests a potentially causal interaction between sleep and affective brain function; nearly all mood disorders display co-occurring sleep abnormalities, commonly involving rapid-eye movement (REM) sleep. Building on this clinical evidence, recent neurobiological frameworks have hypothesized a benefit of REM sleep in palliatively decreasing next-day brain reactivity to recent waking emotional experiences.

Learning by Observation Requires an Early Sleep WindowPNAS

Numerous studies have shown that sleep enhances memory for motor skills learned through practice. Motor skills can, however, also be learned through observation, a process possibly involving the mirror neuron system. We investigated whether motor skill enhancement through prior observation requires sleep to follow the observation, either immediately or after a delay, to consolidate the procedural memory.
