Abstract
Activation of cannabinoid type-1 receptors (CB(1)) is universally recognized as a powerful endogenous orexigenic signal, but the detailed underlying neuronal mechanisms are not fully understood. Using combined genetic and pharmacological approaches in mice, we found that ventral striatal CB(1) receptors exerted a hypophagic action through inhibition of GABAergic transmission. Conversely, brain CB(1) receptors modulating excitatory transmission mediated the well-known orexigenic effects of cannabinoids.Entities:
