Most of the data available come from studies conducted in young adults. Sleep deprivation and neuroimaging studies, as well as works using more original techniques such as transcranial direct current stimulation have allowed precising the electrophysiological bases of the beneficial effect of sleep on memory. They have also leaded to the proposal of relatively accomplished theoretical models (“hippocampo-neocortical dialogue” and “synaptic downscaling hypothesis”). Besides, only few studies have been conducted in children and in older adults but, since few years, these populations have sparked renewed interest in the scientific community. Data in these subjects are crucial for a thorough understanding of sleep-dependent memory consolidation. Studies conducted in schoolchildren underlined the beneficial role of NREM (non Rapid Eye Movement sleep) in the consolidation of declarative memories. In contrast, links between sleep stages and procedural memory consolidation appear less obvious. In older adults, the dramatic decrease in slow wave sleep may explain, at least in part, the decline in episodic memory consolidation. The decrease in acetylcholine levels could be deleterious for procedural memory consolidation.
