Cannabinoid agonists generally have a disruptive effect on memory, learning, and operant behavior that is considered to be hippocampus-dependent. Nevertheless, under certain conditions, cannabinoid receptor activation may facilitate neuronal learning processes. For example, CB1 receptors are essential for the extinction of conditioned fear associations, indicating an important role for this...

Cannabis increases the risk of schizophrenia in genetically vulnerable individuals. In this study we aim to show that the schizophrenia susceptibility gene neuregulin 1 (Nrg1) modulates the development of tolerance to cannabinoids in mice. Nrg1 heterozygous (HET) and wild-type (WT) mice were treated daily for 15 d with the synthetic analogue of Δ9-tetrahydrocannabinol, CP55,940 (0.4 mg/kg). We...

In total, 14 healthy...

Still within the throes of her evangelical ardor, Eliot laments in this letter that the “disjointed specimens” of history, poetry,...

Benzylpiperazine (BZP) is often used alone, or can be combined with trifluoromethylphenylpiperazine (TFMPP). Taken together as an oral dose, they have been reported to produce effects similar to 3, 4-methylenedioxymethamphetamine (MDMA)....
