How Suckling Trains Movement and Brain Clock Areas in Rabbit Babies

Circadian Biology Weekly Brief ↗PubMed ↗DOI ↗

Updated

Abstract

Rabbit pups demonstrate food anticipatory activity with nursing occurring once daily for fewer than 5 minutes.

  • Nursing visits by dams occur during both the dark and light phases, with specific timing affecting pup behavior.
  • Pups show increased locomotor activity before nursing, indicating anticipation of feeding.
  • In the master circadian clock region (SCN), protein levels of PER1 and FOS are elevated at night, particularly in pups fed at night.
  • The dorsomedial hypothalamic nucleus (DMH) shows peak PER1 expression 8 hours after feeding, linked to the timing of nursing.
  • Comparison of nursed and fasted pups reveals fewer PER1-positive cells in the fasted group, suggesting the impact of nursing timing on neural activity.
