Sleep Deprivation and Emotion Recognition

Emotion recognition following early psychosocial deprivation.

An important function of the brain is to scan incoming sensory information for the presence of relevant signals and act on this information. For humans, the most salient signals are often social in nature, such as the identity and the emotional expression of the faces we encounter in our everyday lives. It can be argued that our survival as a species depends in large measure on these skills.

Sleep deprivation impairs object recognition in mice.

Many studies in animals and humans suggest that sleep facilitates learning, memory consolidation, and retrieval. Moreover, sleep deprivation (SD) incurred after learning, impaired memory in humans, mice, rats, and hamsters. We investigated the importance of sleep and its timing in an object recognition task in OF1 mice subjected to 6h SD either immediately after the acquisition phase (0-6 SD) o...

Energy expenditure during sleep, sleep deprivation and sleep following sleep deprivation in adult humans

Sleep has been proposed to be a physiological adaptation to conserve energy, but little research has examined this proposed function of sleep in humans. We quantified effects of sleep, sleep deprivation and recovery sleep on whole-body total daily energy expenditure (EE) and on EE during the habitual day and nighttime. We also determined effects of sleep stage during baseline and recovery sleep...
