Distinct modulation of the endocannabinoid system upon kainic acid-induced in vivo seizures and in vitro epileptiform bursting
There is clear evidence on the neuroprotective role of the endocannabinoid (eCB) signaling

The active heroin metabolite 6-acetylmorphine has robust reinforcing effects as assessed by self-administration in the rat
Previous studies have suggested that at least some of the behavioral effects of heroin might
be mediated by its active metabolite 6-acetylmorphine (6-AM). The aim of the present study …
