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.

Selckmann, Gordon Michael (2010).   An Investigation of the Teleost Sensory Saccular Epithelia: Cranial Nerve Arborization and Innervation of the Saccule Sensory Epithelia.  Mentor: Dr. John Ramcharitar

Abstract 

Members of the teleost family Sciaenidae show significant variation in the inner ear and accessory hearing structures. In this study we examined the inner ear morphology of the sciaenids Micropogonias undulates, Sciaenops ocellatus, Leostomus xanthurus, and from the bass Moronidae family, Morone Americana inner ears were isolated via gross level dissections, arborization of the 8th cranial nerve onto the saccule was studied via osmium staining and hair cell densities over the saccular sensory epithelia via a fluorescent techniques. I found that there are more complex 8th nerve arborization patterns on the saccular sensory epithelium of species with accessory hearing organs. There were also interspecific differences in total numbers of hair cells in specialized species. The more specialized species showed greater numbers of hair cells than generalized species. The morphological specializations of the inner ear and swim bladder of the studied sciaenids may be linked to the enhanced hearing capabilities. The findings of this study suggest the possibility of frequency tuning on the saccular sensory epithium.
