Title: Single-trial image memory

Abstract: Humans have a remarkable ability to remember the images that they have seen, even after seeing thousands, each only once and only for a few seconds. In this talk, I will describe our recent work focused on the neural mechanisms that support visual familiarity memory. In the first part of the talk, I will describe the correlates of the natural variation with which some images are inherently more memorable than others, both the brain as well as deep neural networks trained to categorize objects. In the second part of the talk, I will describe how these results challenge current proposals about how visual familiarity is signaled in the brain, as well as evidence in support of a novel theory about how familiarity is decoded to drive behavior.
