Histamine in the basolateral amygdala contributes to oleoylethanolamide-induced precognitive effects

we investigated if brain HA is also required for OEA-induced promnesic effects. Wistar rats (280-300 g) were submitted to the contextual fear conditioned paradigm and immediately after received a single OEA injection (10 mg/kg, i.p.). Memory was asses- sed as ‘freezing’ (total absence of movements) time 72 h after injections.
