The Human Circadian Rhythm is a fundamental concept in Chronobiology and Neuroendocrinology, frequently asked in CSIR NET Life Sciences, GATE (XL/BT), PGT Biology, and Assistant Professor exams.
In this power-packed lecture, Lifelogy Sensei explains the molecular and physiological mechanisms regulating the 24-hour biological clock, including:
🔬 Topics Covered:
Definition and characteristics of circadian rhythm
Role of Suprachiasmatic Nucleus (SCN)
Light entrainment and photoreceptors
Melatonin secretion and pineal gland regulation
Sleep–wake cycle mechanism
Molecular clock genes (CLOCK, BMAL1, PER, CRY)
Hormonal regulation (Cortisol rhythm)
Jet lag & shift work disorders
Previous year MCQ concepts for CSIR NET & GATE
🧠 This session is extremely important for:
