Recreational drug use among pregnant women is a source of concern due to potential harmful effects of drug exposure on prenatal and infant development. The simultaneous abuse of ecstasy [3,4-methylenedioxymethamphetamine (MDMA)] and alcohol is prevalent among young adults, including young expectant mothers. Here, we used a rat model to study the potential risks associated with exposure to...
It has been hypothesized that changes in striatal-mediated dopamine modulation during adolescence may increase the risk for initiating substance abuse as a result of its fundamental role in arbitrating reward sensitivity and motivation during learning and decision making. However, substance abuse during adolescence may also significantly modify striatal structure and function and concomitantly...
During postnatal days (PD) 11–20, (+/–)3,4-methylenedioxymethamphetamine (MDMA) treatment impairs egocentric and allocentric learning, and reduces spontaneous locomotor activity; however, it does not have these effects during PD 1–10. How the learning impairments relate to the stress hyporesponsive period (SHRP) is unknown. To test this association, the preweaning period was subdivided into...
Efficient reuptake of synaptically released glutamate is essential for preventing glutamate receptor overstimulation and neuronal death. Glutamate transporters play a vital role in removing extracellular glutamate from the synaptic cleft. This study analyzed the expression of the glial (GLAST) and neuronal (EAAC1) subtypes of glutamate transporter in the cerebellum of male and female offspring...
