Young woman asleep over study materials. The relationship between sleep and memory has been studied since at least the early 19th century.Memory, the cognitive process of storing and retrieving past experiences, learning and recognition, [1] is a product of brain plasticity, the structural changes within synapses that create associations between stimuli.
Multiple hypotheses explain the possible connections between sleep and learning in humans. Research indicates that sleep does more than allow the brain to rest; it may also aid the consolidation of long-term memories. REM sleep and slow-wave sleep play different roles in memory consolidation. REM is associated with the consolidation of ...
Senior author of the study, Dr Aidan Horner from the Department of Psychology at the University of York, said: “The relationship between sleep and memory is fascinating. “We know that sleep is ...
Memory lapses like these are common for people of all ages. “Mild forgetfulness — you forget somebody’s name or where you left something — that’s totally normal,” says Karlene Ball, Ph.D.
Researchers have hypothesized that sleep deprivation interferes with the normal reduction in levels of 5-HT, impairing the process of memory consolidation. [48] Another theory suggests that the stress brought on by sleep deprivation affects memory consolidation by changing the concentration of corticosteroids in the body.
A study recently published in the journal Communications Psychology, for example, determined that cycling and high-intensity interval training (HIIT) were most likely to help boost memory ...
Sleep spindles play a crucial role in declarative memory consolidation and both sex and menstruation affect sleep [31] and online learning periods. [32] Studies have shown that the influence of sleep spindles during the declarative memory process may be affected by modulatory menstrual cycle effects in females. [33]
