Figure 6From: Analysis of sleep disorders under pain using an optogenetic tool: possible involvement of the activation of dorsal raphe nucleus-serotonergic neuronsChange in the dialysate levels of 5-HT induced by optical stimulation in the mouse DRN. Extracellular 5-HT content in the PFC during optical stimulation at 20 Hz in the DRN. Values are shown as the means with SEM(n = 3). *p < 0.05 vs. No stimuli.Back to article page
