Optogenetic activation of SOM+ cells triggers OFF periods during NREM sleep. A, Left, Example of MUA changes in two responding (SOM+, green) channels and several SOM− channels after laser stimulation (yellow bar, 50 ms). Right, Mean MUA changes for all SOM+ and SOM− channels (7 mice). Inset, Expanded y-axis to show the firing of SOM+ channels after laser pulse. B, Left, Change in firing in one broad unit (putative excitatory, spike waveform shown on top). Right, Mean of all broad units. C, As in B for narrow (putative inhibitory) units.
