Chronic stress in Wistar rats significantly disrupted circadian rhythms, increasing stress levels by 37% after 14 days of sound exposure. These stress markers remained elevated even after a 7-day recovery period, indicating incomplete physiological recovery.

Area of Science:

  • Physiology
  • Computational Biology
  • Stress Research

Background:

  • Chronic stress significantly impacts physiological functions and well-being.
  • Evaluating stress often relies on subjective measures or limited physiological indicators.
  • Understanding stress-induced circadian rhythm disturbances is crucial for developing effective interventions.

Purpose of the Study:

  • To quantitatively assess chronic stress in Wistar rats using integrated physiological parameters.
  • To develop and validate a neuro-fuzzy inference system for stress evaluation.
  • To determine the extent of circadian rhythm disturbance caused by sound stress and assess recovery.

Main Methods:

  • Wistar rats were subjected to 14 days of sound stress, with hourly biosignal acquisition.

  • An adaptive neuro-fuzzy inference system (ANFIS) was employed to integrate physiological parameters.
  • Cortisol production served as the target output for the ANFIS model.
  • Cosinor analysis was used to analyze 24-hour circadian rhythm patterns.

    • Main Results:

    • The ANFIS successfully integrated physiological parameters to quantify stress levels.
    • A 14-day sound stress exposure increased the stress index from 1 to 1.37 (37% increase).
    • Following a 7-day recovery period, the stress index remained elevated at 1.47, indicating incomplete recovery.

    Conclusions:

    • Integrated physiological parameters, analyzed via ANFIS and Cosinor methods, effectively evaluate chronic stress.
    • Sound stress induces significant and persistent circadian rhythm disturbances in Wistar rats.
    • A 7-day recovery period is insufficient for complete physiological normalization after 14 days of sound-induced stress.
