WELCOME
In particular we work on data collected at our own facilities or from different national and international collaborators namely:
- EEG signals recorded in humans
- Multiunit activity recorded in monkeys and
- Local Field Potentials recorded in patients and monkeys.
As for the methods we are focused on the development of methods to deal with multivariate spatio temporal time series as:
- Short EEG windows as used for the Single Trial anlysis
- Analysis of short non stationary signals in the time and the spectral domain.
- Development of methods for the non invasive estimation of the activity inside the brain.
- Conectivity analysis using scalp measured data, intracranial recordings or Local Field Potentials non invasively estimated from the EEG.
- Multivariate pattern recognition techniques.
The current list of the assets of the ENG includes:
- Proposal of several linear inverse solutions (LAURA, EPIFOCUS, ELECTRA, WROP, ANA) for the estimation of the activity inside the brain and methods for their evaluation.
- Development of the only method available (ELECTRA) for the non invasive estimation of Local Field Potentials (LFP) using external EEG measurements (link here).
- First proposal for the use of inverse solutions for BCI at both the Swiss national level and the international level.
- Development of online EEG analysis methods for Neuro-Rehabilitation and efficient (asynchronous) Brain Computer Interface to control a wheel chair using brain waves.
- First proposal of single trial time frequency analysis of pre stimulus state and correlation with behavior using noninvasive LFP estimated with ELECTRA (link-here).
- First work on mind reading using inverse solution on single trials. Decoding of visual percepts using 500 ms EEG windows and LFP estimated with ELECTRA (link-here)
- Description of the role of very high (>100) frequency oscillations in healthy subjects (link-here)
- Single trial time frequency analysis of emotional states in monkeys and humans. Identification of the image valence using intracranial data measured in monkey or inverse solutions estimates in healthy subjects.
- Identification of the mechanisms of conscious perception and its disturbances in a blindsight patient using non invasive Local Field Potentials.

SUPERVISION / CONSULTING
The Electrical Neuroimaging Group
offers consulting and supervision services for private and public
institutions on the following topics:
- Analysis of electrophysiological
signals (electroencephalogram EEG, electrocorticogram EcoG, Local field
Potentials LFP, Single Unit Activity SUA, Multiple Unit Activity MUA,
Skin Conductance, Electrocardiogram EKG, etc).
- Development and implementation of
realistic head models (MRI based) for source localization in
patients, single subjects (e.g. Epileptic focus localization,
blindsight, etc) or Average Evoked Potentials (event related
potentials).
- Real time EEG analysis for
Brain Computer Interfaces and Neurorehabilitation.
- Development and Implementation of
Brain Connectivity methods.
- Functional activation images based on non invasive estimation of
local field potentials (ELECTRA) and multivariate pattern recognition
methods.
The members of our group have a long tradition and experience supervising / training / teaching different groups and individuals as for example:
- Lemanic Neuroscience Program (Ph. D and Master programs)
- Christoph M. Michel and the Functional Brain Mapping Lab.
- Several Ph.D students and
Post-Doc's e.g. O. Blanke, M.
Murray, S. Morand, etc.
