Matias J. Ison was born in Buenos Aires, Argentina in 1977. He earned his master's degree and his doctorate in physics from the University of Buenos Aires, Argentina, working on the fields of statistical mechanics and computational physics. After further experience at the Laboratoire de Physique Corpusculaire in Caen (France), he joined the Neuroengineering Laboratory at the University of Leicester as a postdoctoral research associate. In 2007 he was appointed as a New Blood Lecturer in Bioengineering at the Engineering department. Dr Ison has been appointed to Visiting Professor positions at the Department of Physics and the Department Computer Sciences, University of Buenos Aires. He has longstanding collaborations with the Department of Neurosurgery, UCLA (USA).
Main Research Interests:
My main area of interest lies at the interface between Engineering and Neuroscience. I am particularly interested in developing and applying quantitative tools (from Engineering, Physics, and Computer Science) to help us understand how the brain works.
My research involves the study of neural activity at very different scales, from single neurons to the study of macroscopic brain dynamics, using a variety of techniques: single-cell recordings in humans, Eye tracking, EEG and modelling. Some of the main projects I am currently involved with include:
- Single cell recordings: In collaboration with UCLA Medical Center (USA), we are studying how new memories are formed by folllowing the simultaneous activity of small groups of neurons recorded from microelectrodes implanted in the brain of epileptic patients for possible curative surgery.
- Simultaneous EEG and eye movements recordings: We recently provided the proof of concept that it is feasible to achieve simultaneous EEG and eye-tracking recordings and, with funding from the EPSRC (project: "Bridging the gap between eye movements and event-related potentials"), we have started to study non-invasively what the brain does while subjects look for targets in a natural scene. This line of research has potential impact in human vision, on clinical work, and other fields (such as the detection of drivers' fatigue).
