# Brain & Mind

Neuroscience, psychology and behaviour: memory, sleep, habits and the brain, from lab findings to everyday life.

## Papers

- [Do Habitual Naps Mean a Bigger Brain?](https://papersays.com/p/do-habitual-naps-mean-a-bigger-brain): A genetic study of UK Biobank volunteers asks whether a napping habit actually changes the brain. The answer is a small yes for brain size, and a no for memory.
- [Why Brain Decoders Drift Between Sessions](https://papersays.com/p/why-brain-decoders-drift-between-sessions): Implanted speech decoders work well on day one and degrade over weeks. A benchmark study tests which recalibration tricks actually help.
- [Irregular Sleep and Later Cognitive Decline](https://papersays.com/p/irregular-sleep-and-later-cognitive-decline): Does going to bed at wildly different times predict memory decline years later? A large cohort says yes, but the story is tangled.
- [Spacing Out Practice to Keep Older Memories Sharp](https://papersays.com/p/spacing-out-practice-to-keep-older-memories-sharp): A 12-week trial asked whether spaced recall practice helps older adults remember everyday information months later. The answer is encouraging, with caveats.
