Dear Discussion List subscribers,


I would to post an advertisement for a PhD position at the Donders
Institute for Brain, Cognition and Behavior.



Mechanisms of top-down control in the accumulation of sensory evidence


Many studies have shown neurophysiological correlates of top-down factors
in perception (e.g., attention and expectation) which are already active
prior to the sampling of sensory evidence. One of the puzzling
observations in this line of investigation is the rather weak relation
between these anticipatory neurophysiological signals (typically,
modulations of oscillatory activity) and perception (most importantly,


The overall objective of this project is to identify additional
neurophysiological processes that explain behavioral accuracy and its
modulation by attention. The main working hypothesis that guides us in
this search is that one should not only investigate anticipatory neural
activity but also the neural activity during the accumulation of sensory
evidence. The objectives of this research project will be addressed in
experiments in which extracranial neural signals are recorded using
Magnetoencephalography (MEG).


Within the Donders Institute (DI), you will belong to the research group
Neurophysiology of Active Perception (PI Eric Maris). As this is a
collaborative project within the DI, you will also be affiliated to the
research groups Prediction & Attention (PI Floris de Lange) and Neuronal
Oscillations (PI Ole Jensen).


A successful candidate has a Master' s degree in a field at the interface
of behavior and neurobiology (Cognitive Neuroscience, Neurobiology,
Cognitive Science) and excellent analytic and quantitative skills.
Programming skills (e.g., Matlab) are required, and it is an advantage if
you have experience in running EEG or MEG experiments.


Please include with your application:

- a curriculum vitae, including academic qualifications, grades, a list of
publications (if applicable), and the names and contact details of two

- a letter explaining your motivation, your interest in the project, and
your competence in the research field;"
