The evaluation of the effects of glycine on sleep in SCNx rats. (a) Representative temperature records (upper) and χ2 periodograms (lower) of sham (left) and SCNx (right) rats. Circadian tau was given for significant peaks (p<0.001). (b) The core body temperature was recorded from 60 min before oral administration in sham (left) and SCNx (right) rats. All values are the mean±SEM (n=6 for sham rats, n=11 for SCNx rats). The asterisks indicate significant differences (*p<0.05). Amount (c), total episode number (d), and mean duration (e) of each stage in sham and SCNx rats during the first 90 min after oral administration. (f) NREM sleep latency was not shortened by glycine administration in SCNx rats.
