Spatial Learning and Reactivation in the Hippocampus and Beyond

On behalf of 'The Memory Tapestry: Weaving Insights Across Different Systems and Levels' Group, Prof. Jozsef Csicsvari will give a talk titled "Spatial Learning and Reactivation in the Hippocampus and Beyond" as part of the ongoing Student/Postdoc-Run Speaker Series (SPRSS).

Abstract:

The talk will cover topics related to a goal learning paradigm in which animals learn the location of food rewards on a cheeseboard maze. It will discuss published work in which online decoding of reactivation content and memory-specific optogenetics reactivation blockade interfered with the future ability of the animal to recall the blocked memories. It will also show data suggesting the place cell representation drift emerges earlier during sleep, when continuous sleep recordings up to 20h were performed. Unpublished work related to brain criticality analysis and its relationship to the ability of the animal to learn and recall spatial memories will also be discussed.
