Exercise harder, remember more

Scientists have found that the more vigorously you exercise, the stronger the response in the brain that helps your memory.

Dim light can make animals dumb

The neurons in the brain make fewer connections in dim light, but they recover quickly after bright light returns.

Sleep helps our brain strengthen memories, and good sleep therefore can help us learn. But that same strengthening can also get in the way.

How does practice make perfect?

People who keep practicing for ~20 mins after they master a skill actually lock in that learning. New learning probably won't interfere with it either.
