Without it, the animals’ memory-based decision-making faltered, say scientists funded by the National Institutes of Health. The researchers blocked learning from, and acting on, past experience by selectively suppressing replay — encoded as split-second bursts of neuronal activity […]
Combining mentally stimulating activities, such as using a computer, with moderate exercise decreases your odds of having memory loss more than computer use or exercise alone, a Mayo Clinic study shows. Included in this report is a video summary of the study results with the lead research.
