Title: A MEG view of the visual brain: insights from visual representations

Last year we proposed a fundamentally novel way to combine MEG and fMRI imaging data in a representational similarity framework, enabling unique access to the dynamic processes of object categorization in the first stages of human vision. In this talk I will discuss extensions of our method to create refined spatiotemporal maps of brain activity and highlight how MEG can extend our view of the visual brain. I will cover studies aiming to identify common and disparate neural mechanisms of letter perception in blind and sighted readers, provide algorithmically explicit models of visual object processing with convolutional neural networks, and resolve the role of cortical oscillations in visual representations.
