MAM animal models
Schizophrenia
In rat models, the specific effect of MAM on neural development depends on the gestational age of the subject. At the seventeenth gestational day (GD17), administration of MAM produces behavioral and histopathological patterns found in schizophrenia. The molecular mechanism behind this model is not fully known. Methylazoxymethanol acetate administered at GD17 reduces the thickness of the hippocampus and the thalamus. The locomotor effects of amphetamines and the spontaneous firing rate of dopaminergic neurons in the ventral tegmental area are increased. In alternating maze tests, GD17 MAM rats quickly learned the first rule, but took longer to accommodate to alterations to the rule; this is thought to indicate deficits in working spatial memory, which is also impaired in schizophrenia.
