Abstract. Rationale: Schizophrenia is a major public health problem that affects approximately 1% of the population worldwide. Schizophrenia-like syndromes can be induced in humans by phencyclidine (PCP), a drug with marked psychomimetic properties. Recent studies show that the behavioural and biochemical effects of PCP in rats are blocked by nitric oxide synthase (NOS) inhibitors, suggesting that...
Schizophrenic patients are deficient in various neurologic measures reflecting information processing. One such measure is prepulse inhibition (PPI) of acoustic startle, in which schizophrenics display less inhibition than normal subjects. PPI is also diminished in rats treated with psychotomimetic drugs such as amphetamine and phencyclidine. PPI has been suggested as a model relevant for studying...
