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.

Previous research has shown that consolidation of spatial learning in the water maze requires the temporoammonic (TA) pathway. The TA pathway is the neuroanatomical projection from the entorhinal cortex to the CA1 region of the hippocampus. The CA1 contains a dense amount of serotonin (5-HT) 1B receptor mRNA. Systemically delivered injections of a 5- HT1B antagonist have improved consolidation of spatial information in rats. However, neuroanatomical specificity of the task is unknown.  In order to further investigate the role of the 5-HT1B receptor in CA1, bilateral injections of the 5- HT1B receptor antagonist SB216641 were directly infused into CA1 of rats via cannulae. Subjects were given hippocampal infusions of SB216641 every other day for two weeks following 40 water maze trails. Twenty-eight days after the initial training, subjects underwent a probe trial in the water maze to test their consolidation and retention of previous training. It was hypothesized that infusions of the antagonist would result in an increased ability to consolidate spatial information. Results of the study did not support the hypothesis.
