Using experiments and a deep machine learning data analysis approach, scientists uncovered the fundamental workings of the hippocampus region of the brain as it organizes memories into time sequences. The work could help future research into cognitive disorders such as Alzheimer's disease and other causes of dementia.

A research team has discovered that communication between two key memory regions in the brain determines how what we experience becomes part of what we remember, and as these regions mature, the precise ways by which they interact make us better at forming lasting memories.

Previous studies have shown that psychedelic treatment with psilocybin relieved major depressive disorder symptoms in adults for up to a month. Now, in a follow-up study of those participants, the researchers report that the substantial antidepressant effects of psilocybin-assisted therapy, given with supportive psychotherapy, may last at least a year for some patients.
