Bullfrogs make ketones in the brain, study finds

Original: 🐸 NEW: Most # animals make ketone bodies in the liver when # glucose runs low, and the # blood carries them to the # bra

A University of Missouri study has found that bullfrogs produce ketone bodies directly inside brain tissue, rather than only in the liver like most animals. In other animals, the liver makes ketones when glucose runs low and the blood carries them to the brain. The discovery suggests frogs can keep neural activity going even when glucose is scarce, and researchers are now asking how widespread this ability is across species.

Why now: New research showing local brain ketone production challenges the standard textbook picture of how animals fuel the brain.
