SMP Spotlight

Katie Gluskin and Jeff Haus present their SMP
Katie Gluskin and Jeff Haus, "Entorhinal Cortex Lesions, Habituation, and Latent Inhibition," 2013. Gluskin and Haus, the 2013 co-winners of the Neuroscience Award, infused a neurotoxin into the entorhinal cortex of rats to induce a lesion, and measured the resulting habituation and latent inhibition behavior within a fear conditioning paradigm.

Placek, Katerina (2012).  Prenatal fluoxetine exposure : mitigation of affective behavioral deficits through neonatal tactile stimulation. (Mentor: A. Bailey)

Abstract 

Fluoxetine (Prozac) is the most frequently prescribed drug for the treatment of depression in pregnant women, but its long-term neurodevelopmental effects on offspring have not yet been established. In rats, prenatal fluoxetine exposure is linked with emotional-behavioral deficits in adulthood and lasting neuroanatomical changes, presumably resulting from the unnatural saturation of the developing brain and nervous system with serotonin. A form of environmental enrichment, tactile stimulation may improve neurodevelopmental outcome in neonatal populations following early-life cortical assault. The present study investigated the novel usage of neonatal tactile stimulation as an intervention in rats prenatally exposed to fluoxetine, examining potential effects of the intervention on behavioral measures of rodent emotionality (open field test, elevated plus maze, forced swim test) and on Golgi-Cox-identified dendritic spine density and length. While Golgi-Cox analysis of histological data is not yet complete, behavioral results denote novel evidence for a) the therapeutic potential of tactile enrichment on anxiety-like behaviors, and b) the differential effects of drug exposure and/or environmental enrichment on behavioral outcome based on sex. Future work on this project will focus on utilizing neurobiological Golgi-Cox data to find a correlation with or causal inference to behavioral data, in the hopes of elucidating the mechanisms by which tactile stimulation confers beneficial outcomes for the comprised neurodevelopment of offspring.
