Abstract: A brain pathway for active forgetting Sleep affects memories via several mechanisms. Izawa et al. identified a possible new pathway in the brain: REM sleep–active hypothalamic melanin-concentrating hormone (MCH)–producing neurons, which, among others, project to… read more here.

DOI: 10.1371/journal.pbio.3000361
Abstract: Sleep-active neurons depolarize during sleep to suppress wakefulness circuits. Wake-active wake-promoting neurons in turn shut down sleep-active neurons, thus forming a bipartite flip-flop switch. However, how sleep is switched on is unclear because it is… read more here.

DOI: 10.3389/fnagi.2019.00058
Abstract: An extensive psychological literature shows that sleep actively promotes human episodic memory (EM) consolidation in younger adults. However, evidence for the benefit of sleep for EM consolidation in aging is still elusive. In addition, most… read more here.
