Fatty acid amide hydrolase (FAAH) is a key regulator of endocannabinoid signalling. Here, the authors develop a knock-in mouse that recapitulates a common human mutation in the FAAH gene and demonstrate parallel neural and behavioural alterations across species, suggesting a gain-of-function in fear regulation.
