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.


Hernandez, Alex (2010).   The Impact Of A Four-Week Escalating Dose Regimen Of Methamphetamine On Cognition And Serotonin Levels Within The Hippocampus In Adult And Adolescent Rats.   Mentor: Dr. Anne Marie Brady


Although recent rates of methamphetamine (METH) use have decreased somewhat, use remains higher among adolescents aged 12-17 than among adults 26 years or older.  Exposure to METH during adolescence could result in neurological damage and psychiatric dysfunction.  The current experiment focused on determining the impact of a four-week escalating dose regimen of METH, beginning in either adolescence or adulthood, on working memory, behavioral flexibility, and levels of serotonin within the hippocampus in 24 male Sprague-Dawley rats.  The use of a four-week escalating dose regimen spans the entire adolescent period in rats and models the typical human pattern of METH use.  Results did not support the hypothesis that all rats exposed to the escalating dose regimen of METH would show significant deficits in working memory and set-shifting, nor reductions in levels of serotonin within the hippocampus, as compared to saline controls.  Results also did not support the hypothesis that adolescent-treated rats would be more susceptible to METH induced cognitive deficits and reductions in hippocampal serotonin levels as compared to adult-treated rats.  Future research should utilize the escalating dose regimen and investigate the role of the HPA axis, pharmacodynamic tolerance, and chronic injection stress in METH induced cognitive deficits.
