Postnatal hypoxia evokes persistent changes within the male rat ’s dopaminergic system

ConclusionPostnatally occurring hypoxic insults promote remodeling of the dopaminergic system resulting in increased intracellular sequestering of this monoamine. That sequestered dopamine can be released using the psychostimulant d-amphetamine, which did not promote a conditioned place preference any greater than was observed in non-hypoxic littermate controls.
