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.

Source: Laboratories of Jonas T. Kaplan and Sarah I. Gimbel—University of Southern California Attention, working-memory, planning, impulse control, inhibition, and mental flexibility are important components of human cognition that are often referred to as executive functions. Autism spectrum disorder is a developmental disorder that is characterized by impairments in social interaction, communication, and repetitive behaviors. It is a disorder that lasts a lifetime, and is thought to affect...

Autism spectrum disorder (ASD) is a neurodevelopmental condition marked by persistent deficits in social communication and interaction alongside restrictive and repetitive behaviors or interests. ASD is sometimes accompanied by intellectual impairment. These core symptoms manifest differently among individuals, ranging from mild to severe. The disorder's complexity extends beyond its clinical presentation, encompassing a diverse range of biological, cognitive, and sociocultural influences.

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.
FAQs
Alcohol can cross the placenta during sensitive periods of embryonic and fetal development. Its presence may interfere with cell proliferation, migration, differentiation, and survival, processes that build tissues and establish neural structures. Disruption at these stages can alter organ formation and brain development, helping explain why Fetal Alcohol Spectrum Disorders may affect learning, behavior, growth, and physical health.
The effects of prenatal alcohol exposure are not uniform because development proceeds through changing sensitive periods, and exposure conditions differ. Timing can determine which developmental processes are active, while dose and individual susceptibility can influence the extent of disruption. Consequently, affected individuals may show different combinations and degrees of brain, growth, behavioral, learning, or physical effects.
Cell proliferation, migration, differentiation, and survival provide a framework for understanding how prenatal alcohol exposure can alter developing tissues. Proliferation affects how many cells are produced, migration helps place cells appropriately, differentiation establishes specialized cell types, and survival determines which cells remain. Studying these processes connects cellular changes with later abnormalities in organ formation and neural development.
Fetal Alcohol Spectrum Disorders provide a model for examining how an environmental factor can modify organ formation and neural development. Researchers can use this context to relate prenatal exposure to changes in fundamental developmental processes rather than viewing outcomes only as isolated symptoms. This model also links developmental mechanisms with variation in growth, learning, behavior, and physical health.
Earlier recognition and improved diagnostic approaches can help identify affected individuals more effectively after prenatal alcohol exposure has influenced development. The need for these approaches reflects the broad and variable nature of outcomes, which may involve brain development, growth, learning, behavior, or physical health. Better recognition can support more appropriate planning for educational, behavioral, and medical interventions.
Support may be directed toward educational, behavioral, and medical needs, with the precise focus guided by the individual's pattern of effects. This approach reflects the variability produced by exposure timing, dose, and individual susceptibility. Linking recognition with targeted support can address consequences across learning, behavior, development, and physical health rather than relying on a single intervention for everyone.
