Understanding the neural basis visual cognition requires to answer the following basic questions: what is happening where and when in the human brain when we see, and how does it relate to behavior? In this talk I will present recent work that addresses these questions in an integrated analysis framework combining human magnetoencephalography (MEG), functional magnetic resonance imaging (fMRI), behavioural assessment and deep neural networks (DNNs). The talk has four parts. In the first part, I will show how fMRI and MEG can be combined using multivariate analysis techniques for a spatiotemporally resolved view of brain activity. Second, I will show how we established whether the activity revealed is indeed used by the brain for behaviour. Third, I will sketch how DNNs can be used to investigate visual coding. In the final part I will describe ongoing work and future directions. In particular, I will propose a (funded) research agenda that aims to resolve spatiotemporal dynamics at the level of cortical layers using ultra-high resolution fMRI and DNN-guided brain mapping.
