abstractText | Habituation (a form of non-associative learning) was measured by assessing locomotion in novel activity monitors in CB1 receptor knockout mice and juxtaposed to habituation measured in muscarinic M2, M4, and double M2/M4 receptor knockout mice. M2 and M2/M4, but not M4, receptor knockout mice appeared to have an impaired ability to habituate, whereas CB1 receptor knockout mice showed enhanced habituation compared to wild-type animals. We conclude that CB1 receptor gene invalidation improves habituation tentatively through an increase in cholinergic neurotransmission. |
