    Abstract:
    In brain medial-basal areas (midbrain, hypothalamus, striatum) ascorbic acid (AA) content is lower than in the rest of the brain. It has been hypothesized that AA may be involved in brain catecholamine metabolism. To test this hypothesis AA content in medial-basal areas and in the remaining brain areas was measured in rats pretreated with alpha-methyl-paratyrosine (alpha-MpT), a tyrosine hydroxylase inhibitor. The AA content, in brain medial-basal areas, had slightly decreased, without statistically significant differences, in rats treated with alpha-MpT in comparison with untreated animals. Therefore the role of AA in brain metabolism is not clear to.
