Research News from the Howard Hughes Medical Institute

Noisy Brain May Help Learning

While most people need peace and quiet to cram for a test, the brain itself may
need noise to learn, a recent study suggests. In experiments with monkeys, the
researchers found that neural activities in the brain gradually change, even
when nothing new is being learned. Challenging the monkeys to adjust their task
triggered systematic changes in their neural activities on top of this
background "noise."

Research published in the May 24, 2007, issue of Neuron.
