Just post the whole thing. This is ridiculous. That means nothing.

Here is a brief explanation of microsleep from one of the papers:

A microsleep is defined as
a 3-14 sec episode during which 4-7 Hz (theta) activity replaces the waking 8-13
Hz (alpha) background rhythm. Microsleep episodes were identified in the
electroencephalography (EEG) record by a neurologist certified by the American
Board of Sleep Medicine. Twenty-four drivers with OSAHS were tested using
simulated driving scenarios. Steering variability, lane position variability,
acceleration and velocity measures were assessed in the periods during a
microsleep, immediately preceding (pre) microsleep, and immediately following
(post) microsleep. In line with our introductory hypothesis, drivers with OSAHS
did show significantly greater variation in steering and lane position during the
microsleep episodes compared to the periods pre and post microsleep. The results
indicate that identification of microsleep episodes can provide a marker for
declining vehicle control of drivers with OSAHS.
