Understanding mesoscale visual processing through the lens of high-resolution functional MRI
Wednesday, June 1, 2022, 12:00 – 2:00 pm EDT, Zoom Session

In the past, our understanding of neuronal processing in mesoscale levels (i.e. the spatial scale of cortical columns and/or layers) relied heavily on invasive techniques, mostly not applicable to humans (or behaving animals). However, with recent advances in high-resolution neuroimaging techniques, our knowledge of mesoscale neuronal processing is expanding rapidly. In this symposium, speakers will describe their recent discoveries about the mesoscale neuronal processing in human visual system. Studying different brain areas, from early retinotopic areas (V1-V4) to higher-level regions (e.g. fusiform and parietal cortex), their findings have opened new horizons to understanding the neuronal underpinning of visual perception.

The interplay of visual memory and high-level vision
Wednesday, June 1, 2022, 12:00 – 2:00 pm EDT, Zoom Session

Every day we come across many visual images, whether on electronic devices, printed matter, or billboards. Some of these are already familiar to us, some are new and are burnt into memory while others are not. While some studies reveal extraordinary human image memory, the factors that influence which images are remembered are far from being understood. In this symposium, presenters studying diverse populations using a variety of techniques will examine different influences on image memory (as physical, categorical, conceptual, developmental and individual differences), their underlying mechanisms and the interplay between perception, visual representations, memory, and behavior.
