53% of dreams can be traced to memories, and of those, 50% are linked to memory sources of multiple previous life events. Additionally, 26% of dreams are associated with impending events. Future-orientated dreams become more prevalent during deeper stages of sleep.
The reactivation of learned material during slow oscillation/sleep spindle complexes, and the precision of SO-spindle coupling predicts how strong a memory will be reactivated in the brain.
Novel experiences dampen previous memory representations in the hippocampus and prefrontal cortex, facilitating flexible strategy encoding in mice.
Adult born neurons are essential for synaptic structural remodeling and memory consolidation during REM sleep, a new mouse study found.
Delivering a memory-inducing scent to one nostril while a person sleeps helps boost memory retention.
The size and shape of neural assemblies, and not the strength of signals processed by neurons or the order in which they fire, is the most critical element of recording episodic memory.
Unexpected rewards boost memories of specific events. The findings may have implications for treating memory problems associated with depression.
A rapid memory system transition from the hippocampus to the posterior parietal cortex is stabilized as we sleep. Sleep and repeated rehearsal of memory jointly contribute to long-term memory consolidation.
