Abstract

Development Cocaine Tyrosine hydroxylase Catecholamine Cortex
Anterior cingulate cortex develops abnormally in rabbits exposed to cocaine in utero but visual cortex is normal. The interactions of cocaine with the dopamine, norepinephrine and serotonin systems makes each a potential candidate for influencing these developmental effects. Here, we report no differences in the distribution and density of serotonin and tyrosine hydroxylase-immunoreactive fibers in the anterior cingulate cortex in postnatal rabbits exposed prenatally to cocaine or saline. Because the pattern and extent of cortical innervation by these systems appears normal, the data suggest that the effects of prenatal exposure to cocaine may involve changes in monoamine signaling distinct from morphological reorganization of the cortical afferents.
