Markram has published more than 100 papers and has an H-index of 53, one of the highest in his area of research and stage of career. Since 2002, Markram has spearheaded Switzerland’s ambition to become a world leader in High Performance Computing and to prioritise simulation-based research; these fields are now two of the three national research priorities declared by the Swiss government (http://www.ethrat.ch/en/ section-general-news/successes-education- and-research-call-more-resources). Markram is also founder of Frontiers (frontiersin.org), a new model for peer-reviewed open-access publishing.

OLIVIER MARRE, UPMC:                                                  

Olivier Marre is an INSERM researcher (since 2013) in the Vision Institute (Paris), working in the team headed by Serge Picaud. He did his PhD (defended in 2008) with Yves Fregnac (CNRS, Gif-sur-Yvette) studying the visual cortex with both theoretical models and intracellular recordings in vivo. He then did a post-doc at Princeton University with Michael Berry, where he developed a new technique to record almost all the output neurons in a patch of retina.

HBP research is organised into twelve Subprojects, each broken down into Work Packages and Tasks, with well-defined goals and milestones. Six Subprojects are building the ICT Platforms, while the other six are gathering data, clarifying theory and controlling ethical aspects. An additional Subproject manages and coordinates the HBP. Theoretical work in the HBP addresses a set of strategic issues, all related to the goal of achieving a multi-level understanding of the brain. The EITN is part of the Theory subproject (SP4).

To fulfil the EITN goals, our Sp partners are all involved in the Institute in someway.

SP4 co-leaders: Alain Destexhe (CNRS) and Wulfram Gerstner (EPFL).

SP4 Objective

“To produce simplified models of complex brain structures and dynamics; rules linking learning and memory to synaptic plasticity; large-scale models creating a bridge between ‘high-level’ behavioural and imaging data; and mathematical descriptions of neural computation at different levels of brain organisation.”
