This study shows that activation of cannabinoid type-1 (CB1) receptors in the olfactory bulb increases odor detection and food intake in hungry mice. The authors show that this function is mediated by CB1-dependent attenuation of excitatory corticofugal synaptic transmission onto inhibitory granule cells and disinhibition of mitral cells in the main olfactory bulb.
