In order to understand the molecular mechanisms of the ethanol-induced developmental damage, we have developed a zebrafish model of ethanol exposure and are exploring the physical, cellular, and genetic alterations that occur after ethanol exposure1. We then seek to find potential interventions and rapidly test them in this animal model.

Trace eyeblink classical conditioning (ECC) was used to assess hippocampal-dependent associative learning in adult rats that were administered a high concentration (11.9% v/v) of alcohol during early neonatal brain development. In general, ECC procedures are sound diagnostic tools for detecting brain dysfunction across many psychological and biomedical settings.

We developed a model of chorioamnionitis to simulate fetal exposure to maternal inflammation (FEMI) without complications of live organisms to examine the effects of FEMI on development of the offspring’s intestinal tract. This allows for study of mechanistic causes for development of intestinal injury following chorioamnionitis.

During mammalian development, early gestational skin wounds heal without a scar. Here we detail a reliable and reproducible model of fetal scarless wound healing in the cutaneous dorsum of E16.5 (scarless) and E18.5 (scarring) mouse embryos.
FAQs
Alcohol crosses the placenta, but the developing fetus has a limited capacity to metabolize it. Consequently, alcohol can remain available to developing tissues while neural structures are forming. This exposure pathway is important in neuroscience because it helps explain how a substance present during pregnancy can affect brain development before birth, rather than acting only after neural systems have matured.
The developing brain may be affected at several coordinated stages, including neuronal proliferation, migration, differentiation, and synapse formation. These processes determine how many neurons develop, where they are positioned, how they acquire specialized functions, and how they connect. Disruption across more than one stage can help account for broad neurodevelopmental differences rather than a single isolated deficit.
Brain development depends on linked cellular events and the formation of functional neural connections. When prenatal exposure interferes with these processes, its consequences may appear across multiple domains, including cognition, learning, attention, behavior, and motor function. The range of affected abilities gives neuroscientists a way to study how altered development relates to later neurodevelopmental outcomes.
These research approaches provide complementary perspectives on prenatal alcohol effects. Clinical studies examine neurodevelopmental outcomes in people, while cellular and animal models allow investigators to study developmental mechanisms more directly. Together, they connect observed differences in cognition, learning, attention, behavior, or motor function with biological changes occurring during brain development.
Research commonly considers differences in cognition, learning, attention, behavior, and motor function. Examining several domains is important because prenatal exposure can be associated with a broad neurodevelopmental profile rather than one uniform outcome. These measures help researchers characterize affected individuals and connect clinical observations with findings from cellular and animal investigations.
By linking developmental mechanisms with observable neurodevelopmental outcomes, research can improve understanding of how affected individuals present across cognitive, behavioral, learning, attentional, and motor domains. Evidence from clinical, cellular, and animal models supports earlier recognition and informs prevention strategies and interventions. This research context also helps explain why support may be relevant across the lifespan.
