Abstract
In this research I will explore how short term memories are supported by the hippocampus and prefrontal cortex. For this project, I trained a cohort of rats on a trace fear conditioning task to evaluate hippocampal-dependent learning and memory. Trace fear conditioning is a hippocampus-dependent learning task that obligates the cohort of rats used to associate an auditory conditioned stimulus (CS) and a minor shock used as the unconditioned stimulus (US) that are separated by an empty trace interval time period. I am currently analyzing the behavior of this cohort through characteristics such as ultrasonic vocalizations (USVs), freezing, and other behavioral traits. With this preliminary data, this project will exploit the effective methods of chronic electrophysiological and calcium imaging recordings in the future. These techniques will be used to probe how sleep influences long-term changes in cortical neurons following learning of a trace fear-conditioning memory task.
