"Neural Dynamics of Working Memory" Dr. Tim Buschman (Department of Psychology and Neuroscience, Princeton University)

Abstract: Working memory is our ability to hold things ‘in mind’, acting as a flexible substrate on which thoughts can be placed and manipulated. Despite its importance to cognition, working memory is surprisingly fragile: working memory representations degrade over time and are susceptible to interference from other stimuli. In this talk, I will discuss two ways in which neural dynamics may help to protect working memory. First, I will discuss how attractor dynamics within memory space can mitigate the impact of neural noise. In particular, as sensory information degrades, attractor dynamics integrate prior beliefs into the memory. Second, I will discuss how sensory representations dynamically transform into working memory representations in a way that avoids interference. Together, these results highlight the role of dynamics in protecting the contents of working memory from noise and interference.
