Nurith Amitai, Susan B Powell, Jared W Youn. Phencyclidine increased while isolation rearing did not affect progressive ratio responding in rats: Investigating potential models of amotivation in schizophrenia. Behavioural brain research. vol 364. 2020-02-13. PMID:29175446. |
animal models of schizophrenia are required to test targeted treatments and since patients exhibit reduced effort (breakpoints) for reward in a progressive ratio (pr) task, we examined the pr breakpoints of rats treated with the nmda receptor antagonist phencyclidine or those reared in isolation - two common manipulations used to induce schizophrenia-relevant behaviors in rodents. |
