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.


Swanson, Thomas (2011).  Effect of adolescent olanzapine administration on dendritic branching in the hippocampal circuit. (Mentor: A. Bailey)


Anti-psychotic drugs are frequently prescribed to adolescents. The long-term treatment effects of these drugs are poorly understood and may be particularly dangerous in relation to the undeveloped nervous system. We investigated the effect of the atypical anti-psychotic drug olanzapine on the developing adolescent hippocampal formation in orally-treated male Long-Evans rats. Cells from both the hippocampus CA3 and dorsal dentate gyrus of each brain were digitally reconstructed and analyzed for changes in dendritic branching length and node prevalence. There were no differences in node prevalence or dendritic branch for both apical and basal portions of hippocampus CA3 neurons. No difference was observed in node prevalence in dentate gyrus granule cells. Olanzapine-treated animals had significantly greater dendritic branching length in the dentate gyrus than water-vehicle controls. We purpose the observed changes in the dentate gyrus and subsequent hippocampal circuitry provide a neuroanatomical explanation for previously observed deficits in spatial memory and concentration ability in rats treated with olanzapine during adolescence.
