Cognitive neuroscience continues to build meaningful connections between affective behavior and human brain function. Within the biological sciences, a similar renaissance has taken place, focusing on the role of sleep in various neurocognitive processes and, most recently, on the interaction between sleep and emotional regulation. This review surveys an(More)
STUDY OBJECTIVES Investigate the impact of sleep deprivation on the ability to recognize the intensity of human facial emotions. DESIGN Randomized total sleep-deprivation or sleep-rested conditions, involving between-group and within-group repeated measures analysis. SETTING Experimental laboratory study. PARTICIPANTS Thirty-seven healthy(More)
While a role for sleep in declarative memory processing is established, the qualitative nature of this consolidation benefit, and the physiological mechanisms mediating it, remain debated. Here, we investigate the impact of sleep physiology on characteristics of episodic memory using an item- (memory elements) and context- (contextual details associated(More)
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(More)
