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.

Chaudhary, Sheena (2010).  Long-term Effects of Adolescent Antipsychotic Drug Treatment on Reward-related Behavior and Cognition Functioning in Adult Rats. (Mentor: A. Bailey)

Abstract 

Antipsychotic drugs, such as the atypical drug olanzapine, are used to treat schizophrenia and bipolar disorder. Olanzapine acts on the dopamine system and is usually administered during adolescence, when schizophrenia is typically diagnosed. However, it is unknown if drug administration during neuronal development will result in long term changes in the brain and behavior. Twenty-one Long-Evans animals were used and were treated with olanzapine during adolescence for a period of 21 days (PD28-PD49). When tested in adulthood for reward sensitivity with a progressive ratio task (PR), an FR 5choice task, and tested for cognition with a set-shifting task, control and olanzapine animals did not show significant differences in behavior. Olanzapine animals did appear to have potential differences in spatial processing as measured by the set-shifting task. However, there was a trend present indicating that olanzapine animals gave up sooner and were not as motivated for food rewards as compared to the control animals in both the PR and FR5 choice tasks.
