Title: Using spatial navigation to understand human learning and memory

 Date: Monday, December 17th, 2018

Time: 11AM

Location: Herklotz Conference Center, Center for Neurobiology of Learning and Memory

Abstract:

Navigation is a central part of daily life. For some, getting around is easy, while others struggle, and certain clinical populations display wandering behaviors and extensive disorientation. Working at the interface between immersive virtual reality and neuroimaging techniques, my research uses these complementary approaches to inform questions about how we acquire and use spatial knowledge. In this talk, I will discuss both some of my recent work and upcoming experiments that center on three main themes: 1) how we learn new environments, 2) how the brain tracks spatial information, and 3) how individuals differ in their spatial abilities. More broadly, I will discuss how navigation lends insight into processes of human learning and memory. The behavioral and neuroimaging studies presented in this talk inform new frameworks for understanding spatial knowledge, leading to novel approaches to answering the next major questions in navigation, learning, and memory.

Title: How memories endure: memory reactivation during sleep and wake

Date: Tuesday, December 18th, 2018

Time: 11AM

Location: Herklotz Conference Center, Center for Neurobiology of Learning and Memory

Abstract:

Memories change over time, as some of their features become weaker (forgetting) and others become stronger (consolidation). In this talk, I will investigate how long-term memory change is modulated by reactivation during sleep and wake. First, I will focus on a technique that involves presenting learning-related stimuli during sleep (termed targeted memory reactivation, or TMR). My findings show that TMR benefits memory retention for numerous types of memory. Crucially, they also point to a specific physiological process – the sleep spindle – that is essential for optimal memory reactivation during sleep. Next, I will present a theoretical framework that addresses how retrieval (vs. restudy) affects the neurobiological underpinnings of long-term memory; I will present results that support this framework as well as future plans for testing the framework. Last, I will discuss a separate line of work asking how individual episodes become abstracted into gist-based representations in a spatial domain, including results from a neuroimaging study that uses a virtual reality environment to reconstruct memory for locations. Cumulatively, these findings significantly contribute to understanding how reactivation benefits and shapes memory consolidation.
