Sleep research high-resolution images show how the brain resets during sleep

Striking electron microscope pictures from inside the brains of mice suggest what happens in our own brain every day: Our synapses -- the junctions between nerve cells -- grow strong and large during the stimulation of daytime, then shrink by nearly 20 percent while we sleep, creating room for more growth and learning the next day.
