Decay chemicals activate a pH-sensing pathway to initiate a persistent state

Grace Margaret Padilla, Matthew L. White, Ming Tak Ngan, John Jefferson, Jennifer Swindlehurst-Chan, Kathleen A. Martin, Matthew Lovett-Barron

The paper shows that cadaverine activates trigeminal chemosensation in zebrafish, leading to a persistent behavioral state through pH sensing, independent of olfaction.
