Dr. Collins et al., THE ACTION OF SYNTHETIC CANNABINOIDS ON THE INDUCTION OF LONG-TERM POTENTIATION IN THE RAT HIPPOCAMPAL SLICE, European journal of pharmacology, 259(3), 1994, pp. 180000007-180000008
Incubation of rat hippocampal slices with the synthetic cannabinoid (-
)-11-OH-Delta(8)-dimethylheptyl tetrahydrocannabinol (HU-210) (100 nM)
prevented the induction of long-term potentiation of field excitatory
postsynaptic potentials recorded in the CA1 region. However, in slice
s incubated with its non-psychoactive(+)-isomer HU-211 (100 nM), which
is reported to be an NMDA receptor antagonist, high frequency stimula
tion evoked a long-lasting potentiation, comparable to control slices.
