Extending lifespan has mixed effects on learning and memory

ScienceDaily (2010-05-19) — Decreasing the intake of calories and tweaking the activity of the hormone insulin are two methods long known to increase lifespan in a wide range of organisms. In particular, studies have shown that longevity can be extended by reducing activity in the insulin-signaling pathway — a chain of events through which insulin influences numerous biological processes, including metabolism, stress response and development. Now, biologists have found the first evidence that these mechanisms also have an impact on cognitive function.
