Rapid eye movement sleep (REM) is often considered as a homogeneous state of sleep, defined by a striking resemblance of its electroencephalogram (EEG) to the one observed in wakefulness. The occurrence of transient events in REM, such as limb twitches or facial and rapid eye movements, supports the view of a paradoxical state of sleep. Here, we investigated the local activity of the primary somatosensory or barrel cortex (S1) in naturally sleeping head-fixed male mice during REM. Through local field potential (LFP) recordings, we uncovered local appearances of spindle waves in the barrel cort
