PhD-position on a Collaborative Project at the NICI (Nijmegen
Institute of Cognition and Information) and the FCDC (F.C. Donders
Center for Cognitive Neuroimaging)
We are seeking a candidate for the PhD project Beamforming for
Cognitive Applications. This project is supervised by Eric Maris
(NICI/Biological Psychology), Robert Oostenveld (FCDC), and Ole
The golden standard in cognitive neuroscience are measurements of
electromagnetic signals at locations in the brain from where they
originate physiologically. Unfortunately, in human cognitive
neuroscience, we can only measure electromagnetic signals at some
distance from their physiological origin, via the EEG or the MEG.
Source reconstruction techniques, such as the beamformer, are then
used to infer a signal at the source level (the brain’s grey matter)
from an observed signal at the sensor level. The beamformer has
several distinct advantages over other source reconstruction
techniques (applicable to evoked responses and induced oscillations,
unique solutions, no assumptions about the source model, excellent
spatial resolution). Unfortunately, it has several disadvantages when
applied to the data of cognitive experiments (only applicable to
single experimental conditions, requires a high SNR, no
quantification of spatial uncertainty). In this project, three
methodological innovations are proposed that extend the beamformer
such that it becomes suitable for cognitive experiments. These
innovations will be implemented in the Matlab toolbox Fieldtrip
(http://www.ru.nl/fcdonders/fieldtrip/) and tested on MEG-data from
existing cognitive neuroscience experiments.
* A master degree in engineering, neuroscience, cognitive science,
biology, applied statistics, or a related field.
* Experience with programming, preferably in Matlab.
* A scientific interest in how the brain works.
