Viktor K. Jirsa Biography

Viktor K. Jirsa is one of the most popular and richest Physicist who was born on June 27, 1968 in Prague, Czech Republic.

Since the late 1990s, Jirsa has made important contributions to the understanding of the link between brain function and network dynamics. He has pioneered the use of biologically realistic connectivity in brain network models of the human and rodent. Applications of this large-scale modeling approach are in resting state activity, epilepsy and aging. Viktor Jirsa has a leading role in the French efforts in personalized medicine and serves as scientific director of the large multi-site clinical trial on drug-resistant epilepsy called EPINOV coordinated by Prof. Fabrice Bartolomei. This project represents one of the first translational applications of computational neuroscience in personalized medicine. Viktor Jirsa is the curator of the neuroinformatics platform The Virtual Brain and deputy-lead of the theoretical neuroscience subproject (SP4) in the Human Brain Project (HBP).

Viktor Jirsa obtained his Master of Science in elementary particle physics from the University of Manchester (UK) in 1991. He then pursued his master studies in philosophy and a diploma in physics (1994), followed by a PhD in theoretical physics (1996) under the supervision of Hermann Haken at the University of Stuttgart, Germany. After two years of post-doctoral training under the mentorship of J. A. Scott Kelso, he became assistant professor (tenure track 1999) and then associate professor (tenure, 2004) in physics and complex systems and brain sciences at Florida Atlantic University, US. In 2006 he accepted a senior researcher position as director of research at the Centre National de la Recherche Scientifique (CNRS) in Marseille, France, at the Institut des Sciences du Mouvement UMR6233, CNRS-Aix Marseille Université. Together with Patrick Chauvel, he founded in 2012 the Institut de Neurosciences des Systèmes(INS), UMR1106, Inserm – Aix-Marseille University, where he currently serves as its director.

Epilepsy is defined by the onset and offset of high-frequency discharges. Nonlinear dynamic system theory teaches us that there is only a finite number of ways to start and stop an oscillation. Based on this insight, Jirsa and colleagues (2014) used first principles rooted in mathematics and bifurcation theory to derive a taxonomy of seizures, which identifies 16 classes via their scaling behaviour of amplitude and frequency at seizure onset and offset. A generative canonical model based on ordinary differential equations unambiguously characterises each seizure type and produces biologically realistic seizure dynamics. More traditional biophysiologically realistic neuronal population models can be mapped upon the seizure taxonomy and thus provides constraints upon their parameters for each seizure type. In particular, some seizure types can be triggered via stimulation and others cannot, which can be deduced from the taxonomy. There is one seizure type, which appears to be predominantly present and invariant across species (zebra fish, mouse, human). The corresponding mathematical model is called Epileptor and comprises two ensembles and a slow permittivity variable. The first ensemble is linked to the generation of fast oscillations, the second ensemble to the interictal spikes and the often-present spike-wave complex close to seizure offset. The slow permittivity variable accounts for, presumably predominantly, extracellular effects related to energy consumption and oxygen and captures details of the autonomous slow evolution of interictal and ictal phases, as well as various details of seizure evolution during each phase. The Epileptor has made a range of predictions that have been successfully experimentally confirmed, including DC-baseline shift at seizure on/offset, epochs of refractoriness for stimulation, routes towards and out of refractory status epilepticus (El Houssaini et al., 2015) and others. The Epileptor since then has inspired various other groups to do research in this field and serves as a network node mode in connectome-based brain network models of epileptic patients.
