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.

Holmes, Ashley (2011).  Effects of orexin A in the nucleus basalis magnocellularis (nBM) on olfactory discrimination acquisition and reversal.  (Mentor: A. Bailey)

Abstract 

The orexins or hypocretins are a family of neuropeptides found in a variety of different brain structures.  The orexins produce excitatory effects and can be split into two types, orexin A (OxA) and orexin B (OxB). The orexins originate in the lateral hypothalamus but project to various other areas of the brain. Orexin interactions with the basal forebrain cholinergic system (BFCS) in particular are hypothesized to be related to arousal and attention and the BFCS is seen to be responsible for normal attentional functioning. Previous research shows that OxA plays an important role in the BFCS attention system. Therefore, we looked at the effects of OxA in an olfactory discrimination acquisition and reversal task. Results supported the hypothesis that orexin A infusions in the nBM did significantly increase attention on olfactory discrimination acquisition and reversal. Therefore, in general, rats who received OxA infusions did have an increase in attention when compared to rats given aCSF infusions.
