Quantitative analysis showed that prenatal morphine exposure decreased the total length, branch number, and spine density of the layer II/III pyramidal neurons in the V2L, and selectively altered the totalLength of the basal dendrites but not of the apical dendrite, which may provide the mechanistic understanding of the behavioral changes in the children whose mothers abuse opiates during pregnancy.

Preclinical rodent experimental observations argue against overt neurotoxic effects of morphine exposure during the brain growth spurt by showing that neither single bolus nor repeated administration of morphine affected the density of these postsynaptic structures.

Direct evidence is provided for structural alterations in VTA dopamine neurons as a consequence of chronic opiate exposure, which could contribute to changes in mesolimbic dopamine function associated with addiction.
