The neuropeptide vasopressin is now known to be released in the brain where it plays important roles in social behaviours. We have shown that the rat olfactory bulb (OB)1 and the anterior olfactory nucleus (AON)2 contain large populations of interneurones which express and release vasopressin. In the OB, single cell recordings from mitral cells in vivo showed that vasopressin modulates the processing of information by olfactory bulb neurones. Block...
