The effect of intraperitoneally injected delta-sleep-inducing peptide (DSIP) on sleep-wakefulness in cats was studied using EEG, EMG and EOG recording for 10 h following 30 nmol/kg DSIP or control saline i.p. injections. DSIP reduced the amount of sleep, specifically light slow-wave sleep and REM sleep, and REM sleep latency was increased. The results suggest that in cats with redundancy sleep DSIP increases wakefulness at the cost of light slow-wave sleep, and in addition it has a specific REM-reducing effect.
通过脑电图（EEG）、肌电图（EMG）和眼电图（EOG）记录，研究了腹腔注射δ-睡眠诱导肽（DSIP）对猫睡眠-觉醒的影响，在腹腔注射30 nmol/kg DSIP或对照生理盐水后记录10小时。DSIP减少了睡眠时间，特别是浅慢波睡眠和快速眼动睡眠，并且快速眼动睡眠潜伏期增加。结果表明，在有多余睡眠的猫中，DSIP以浅慢波睡眠为代价增加觉醒，此外它还有特定的减少快速眼动睡眠的作用。
