"Mnemonic Inertia: Uncovering lingering states in human memory" - Dr. Katherine Duncan (Univ. of Toronto)
The Center for Cognitive Neuroscience Fall Colloquium Series. A fundamental question in the study of memory is why we remember some events and not others. Researchers have tended to approach this question by isolating discrete memory events from the backdrop of ongoing cognitive and neural processing. Despite its many successes, this approach neglects the processes that occur both before and after an event. Our research explores the possibility that this ongoing processing influences the fate of a memory. Specifically, we test how neuromodulators, like dopamine and acetylcholine, and the experiences that trigger their release, establish prolonged cognitive states, which facilitate either memory encoding or retrieval.
