Fetal Alcohol Spectrum Disorders are the most common non-genetic cause of neurodevelopmental disability worldwide. Individuals with Fetal Alcohol Spectrum Disorder experience clinical symptoms including differences in physical, cognitive and behavioral development beginning in early childhood, but continue to face challenges into adulthood. There is a critical need to examine the effects of prenatal ethanol exposure across early development, and to establish how the developmental effects of prenatal ethanol exposure may or may not progress in aging individuals. To contribute to these two areas, I asked how a binge-type prenatal ethanol exposure might affect: (1) early postnatal development of striatal neurons …

Animals rely on a variety of internal and external cues to orient themselves when navigating their environments and determining their current spatial context. Information regarding these cues enters the brain from the navigator’s first-person perspective. Information of this type is considered to be egocentric, or self-centered. However, decades of behavioral, electrophysiological, and imaging research suggest that the brain contains a rich collection of spatial representations that are unrestricted by the animal’s first-person perspective, and instead are defined relative to the surrounding environment. These representations are considered allocentric, or world-centered. Despite an abundance of promising modeling work, the specific mechanisms by …
