    FIGURE 4 Increased anandamide (AEA) signalling at TRPV1s augmented freezing behaviour at extinction training and retrieval in females. (a–f) Treatment with the AEA hydrolysis inhibitor URB597 with concurrent blockade of CB1 receptors with the antagonist AM251 (URB597 + AM251) induced fear generalization, impaired within-session extinction and extinction retrieval. These effects were mediated by AEA signalling at TRPV1s, as they were completely blocked by concomitant injection with theTRPV1 antagonist capsazepine (CPZ) (URB597 + AM251 + CPZ). Furthermore, treatment with URB597 alone induced an overall reduction of darting behaviour during conditioned stimulus (CS) presentation at extinction training compared to the vehicle group.
