My research interest is based on using rodent models of Alzheimer’s disease and the recovery of cognitive functions. The rat Alzheimer’s model is produced by chronic infusion of neurotoxins. I am interested in the effects of intracranial self-stimulation and deep brain stimulation in an animal model of Alzheimer’s disease and its effects on attention/learning/memory and neurogenesis. My lab uses various behavioral assessments including the Social Discrimination test, Morris water maze for testing learning/memory, and a ‘serial reaction time task’ for the testing of attention.
Currently, I am looking at the behavioral and cognitive deficits, as well as sleep-wake measures in streptozotocin-induced [neurotoxin] rats. The goal of this study is to identify the biomarkers of Alzheimer's disease and measure changes in sleep/wake patterns in rodents.
