The Brain's Secret For Sleeping Like a Log
An anonymous reader writes "Why can some people sleep through anything? According to this article in Wired Science, some lucky people have an extra helping of a certain kind of brain static that essentially blocks out noise and other stimuli. These 'sleep spindles' can be detected via EEG, and show up as brief bursts of high-frequency brain waves; some people naturally produce more than others. The researchers say these spindles are produced by the thalamus, the brain region that acts as a waystation for sensory information. If the thalamus is busy producing sleep spindles, sensory information can't make it through the thalamus to the cortex, the perceptive part of the brain."
Yet, this doesn't explain why I can't sleep at 11:30pm when the house is dead quiet. {sigh}
Serious? Seriousness is well above my pay grade.
