Daily Body Temperature Rhythms in Japanese Quail and the Roles of Their Eyes and Pineal Gland

AI simplified

Abstract

Japanese quail maintain a circadian rhythm in body temperature that is significantly impacted by eye removal.

  • Quail exhibit a consistent daily cycle in body temperature that can be influenced by light-dark cycles.
  • Pinealectomy alone does not significantly alter the body temperature rhythm in quail under various lighting conditions.
  • Most quail retain their rhythmic temperature patterns after optic nerve section, though some show reduced robustness and 25% become arrhythmic.
  • Quail subjected to both pinealectomy and optic nerve section demonstrate similar rhythmic behavior to those with optic nerve section alone.
  • Complete eye removal results in all quail becoming arrhythmic in constant darkness, indicating the eyes play a crucial role in maintaining circadian rhythms.
