Sleep biology: tuning in while tuned out

Curr Biol. 2012 Nov 20;22(22):R945-7. doi: 10.1016/j.cub.2012.10.011.


The barrel cortex and whisker thalamus preferentially respond to whisker movements during REM sleep in infant rats. Understanding why the brain tunes into sensory signals while it's tuned out in sleep may provide clues about the functions of REM sleep.
