POSTDOC POSITION at Marseilles, France, in EEG-fMRI recordings, EEG signal
processing, fMRI analysis.

Project funded by Agence Nationale de la Recherche

 

Topic. Measurement of functional connectivity in simultaneous EEG-fMRI
recordings 

 

Context. There is a growing interest in non-invasive measurements of
functional connectivity in the human brain, based on functional magnetic
resonance imaging (fMRI) or high-resolution EEG. Still, there is no
consensus on the best methodology to use, and on the concordance or
discrepancy between modalities. Also, these measures have been performed on
separate recordings, even though it is now possible to perform simultaneous
EEG-fMRI recordings. The simultaneous recordings have the great advantage to
permit to compare the modalities in the exact same brain state, in
particular in terms of habituation, learning and vigilance. Moreover, the
simultaneous EEG recordings permit (i) to track fluctuations in brain
response or state, and (ii) obtain a marker of spontaneous activity such as
alpha waves or epileptic discharges, which brings additional information for
the fMRI analysis.

 

We propose a postdoc position for 18 months to use simultaneous recordings
in epileptic patients for computing connectivity both in EEG and fMRI (3T
Verio Siemens scanner devoted to research), in a face recognition paradigm,
with emphasis on the ventral stream connectivity. We will use intracerebral
EEG recordings in epileptic patients in order to validate the non-invasive
results and to better understand the links between electrophysiology and
fMRI signals.

Salary : 1800 Euros net per month for 18 months.

Skills.  EEG-fMRI recordings, EEG signal processing, fMRI analysis
