The perceptual network group aims to better understand visual perception through its interplay with cognition and action. We study how vision and its interrelated aspects arise from quickly coordinated activity in multiple brain areas, using a dynamic network approach that combines EEG source-imaging, fMRI and Granger-causal modeling with high temporal resolution. The lab follows three parallel research approaches: one investigates the dynamic interactions underlying vision in humans, a second systematically evaluates the performance of existing connectivity methods, and a third aims to identify the elementary cortical interactions underlying visual processes in animal models. This way we aim to link psychological theories to elementary mechanisms, and to provide a better understanding of visual functioning.

Bio

I am a cognitive and biological psychologist with a Master’s degree from the University of Amsterdam (the Netherlands). During my Ph.D. at Riken BSI (Tokyo, Japan) I used psychophysics and eye-movement recordings to study context effects in vision, and located their neural correlates using MEG. As a post-doc at EPFL, Switzerland, I set up an EEG laboratory and mastered EEG source-imaging techniques to study dynamic visual processes in healthy subjects, and in aging and schizophrenic populations. I then received an SNSF Ambizione grant to work at the University of Geneva, where I improved and validated the Granger-causal modelling approaches and applied them to study sensory processing in humans and animal models. My current work is funded by an SNSF professorship grant.
