A must read for Neuro-Physio lovers! How estrous cycle phase interacts with hunger states to dictate aggressiveness towards pups! Discussing the Biorxiv version at journal club was a blast. Congrats Jonny kohl and colleagues!
Researchers at the Crick found that virgin female mice can become aggressive towards pups when hungry, but only in certain hormonal states.
It highlights the importance of understanding hormones when observing how different physical states interact in the brain.
