Collaborators


Prof. Taufik Valiante – Director – Surgical Epilepsy Program, University Health Network, Division of Neurosurgery, Department of Surgery, University of Toronto, Canada.

Dr. Taufik Valiante is a major collaborator at multiple levels and instrumental to realize state-of-the-art methodological analysis of cross-frequency interactions at the mesoscale, of deciphering cell-type specific dynamic circuit motifs at the microcircuit scale, and Dr. Valiante is instrumental and key facilitator for the electro-corticographic (ECoG) recordings of human patient brain signals during complex cognitive attention tasks. Dr. Valiante is the founder and lead neurosurgeon of the Surgical Epilepsy Program of the University Health Network, Toronto Western Hospital. Here some visible outcomes of the joint collaborative work.

Collaborative Brain in Action Program

The Brain in Action CREATE program is an NSERC-funded research training partnership between Canadian members at York University (Toronto), Western UNiversity, (London, Ontario), and Queens Universities (Kingston, Ontario), in partnership with members of the Perception and Action Groups at Justus-Liebig-Universitat Giessen (JLU), and Philipps-Universitat Marburg (UMR), Germany. Together, we form the Brain in Action International Research Training Group (IRTG), which involves both international instruction and international research exchange projects. The goal of this IRTG program is to pool our considerable resources to deepen our understanding of the neural systems and processes that underlie perception and action in everyday living. In addition, the Canadian program prepares trainees to apply this knowledge outside of the university setting, through research collaborations and internships with our non-Academic partners.
