Self-generated whisker movements drive state-dependent sensory input to developing barrel cortex [article]

James C Dooley, Ryan M Glanz, Greta Sokoloff, Mark S Blumberg
2020 bioRxiv   pre-print
Over half of the observed cortical activity was attributable to whisker movements, especially to the myoclonic twitches that occur during active (REM) sleep.  ...  These results highlight the role of sensory feedback in driving early cortical activity and underscore the critical importance of monitoring sleep-wake states for accurate assessment of the contributions  ...  Thus, perhaps inattention to behavioral state leads to failures to detect movement-driven activity [8] .  ...

2017 PLoS ONE  
Moreover, subtle body movement patterns, which may characterize arousals both in human and in animals, are usually not detectable by eye perception and are not in general present in sleep studies.  ...  Noteworthy, our findings suggest an unique dynamical behavior pattern preceding an arousal of AR data during sleep.  ...  As previously shown [17] , AR can express breathing movement, heart beating, tremors or limb movement.  ...
