CB1 Receptors in the Anterior Piriform Cortex Control Odor Preference Memory (Current Biology)

Terral et al. explore the role of the endocannabinoid system in olfactory memory functions. They show that cannabinoid type-1 (CB1) receptors control the retrieval of appetitive, but not aversive, olfactory memory, associated with a modulation of local inhibitory transmission onto specific principal neurons of the anterior piriform cortex.
