[Pentobarbital-Induced Sleep Test Animal Model]
*Appropriateness of Animal Models
  • Sleep is a behavioral phenomenon that cannot be directly assessed at the cellular level, making animal models essential
  • The pentobarbital-induced sleep test, using pentobarbital anesthesia, is a widely used model for evaluating sleep functionality
  • This animal model utilizes the characteristic that mice administered a sleep aid (or functional sleep ingredient) before anesthesia fall asleep faster (significantly reduced sleep latency) and sleep longer (significantly increased sleep duration) compared to the control group
  • The detailed experimental procedure of the pentobarbital-induced sleep test is illustrated in the following schematic diagram
*Rationale for Biomarker Selection
  • (Sleep latency) The time taken to fall asleep, one of the most well-known biomarkers for sleep functionality evaluation.
  • (Sleep duration) It refers to the period from the loss of the righting reflex until its recovery, and is widely used together with sleep latency as a key biomarker for sleep functionality evaluation
  • (Rationale) Difficulty falling asleep or maintaining sleep indicates potential sleep issues. Therefore, a decrease in sleep latency and an increase in sleep duration are key biomarkers for evaluating sleep improvement.
  • (Measurement method) Sleep latency is measured as the time from pentobarbital injection to the loss of the righting reflex, while sleep duration is the time from the loss of the righting reflex until its recovery.
[Analysis of Sleep Architecture Animal Model]
*Appropriateness of Animal Models
  • Analysis of sleep architecture animal model utilizes mice or rats, as these rodents share similarities with humans in terms of sleep homeostasis regulation, circadian rhythm, and sensitivity to internal and external stimuli
  • Unlike other health-functional animal models, which induce symptoms, this model directly evaluates sleep functionality, as rodents naturally experience fragmented sleep, making them an inherent insomnia model
  • Therefore, the functionality evaluations of sleep aids and functional sleep ingredients published in research studies have been conducted without inducing an insomnia model
  • In the analysis of sleep architecture animal model, evaluations are conducted in a specialized chamber with lightweight mice, recording electroencephalogram (EEG) and electromyogram (EMG) to analyze sleep structure, making it the most systematic and objective method for assessing sleep functionality
*Rationale for Biomarker Selection
  • (Sleep latency) The time taken to fall asleep, one of the most well-known biomarkers for sleep functionality evaluation.
  • (Sleep duration of NREMS) Sleep is classified into rapid-eye movement sleep (REMS) and non-rapid eye movement sleep (NREMS). REMS is associated with dreaming and wake-like brain activity, while NREMS is generally considered an indicator of deep sleep.
  • (Rationale) Difficulty falling asleep or maintaining sleep indicates potential sleep issues. Therefore, a decrease in sleep latency and an increase in sleep duration are key biomarkers for evaluating sleep improvement.
  • (Measurement method) After administering the functional sleep ingredients, 24-hour EEG and EMG recordings are analyzed using sleep architecture evaluation programs (e.g., SleepSign) to classify NREMS, REMS, and wakefulness, providing a comprehensive assessment of sleep architecture.
