Alpha waves close your mind for distraction, but not continuously, research suggests. FULL STORY. Alpha waves were long ignored, but gained interest of brain researchers recently.

When we drift off to sleep our brains exhibit Delta waves. The interesting thing about television and brain function is that for the most part, our brains seem to turn off during television programs. When we view television, our brains mostly exhibit slow Alpha waves and waves bordering on Delta waves.
