Invitation to the CCNi debate - ‘Does BOLD fMRI reveal Pseudo
Neuronal Activity?’
We would like to invite you to the Centre for Cognitive
Neuroimaging (CCNi) debate on Monday 1st February 2010 at 2pm.
The debate will be chaired by CCNi director Professor Philippe G. Schyns and will
feature 4 international panel members debating the topic ‘Does BOLD fMRI reveal Pseudo Neuronal Activity?’
Panel members are:
Professor Aniruddha Das (Department
of Neuroscience, Columbia University); Professor
Martin Lauritzen (Department of Clinical Neurophysiology, Glostrup
Hospital, Denmark); Professor Nikos
Logothetis (Max Planck Institute for Biological Cybernetics,
Tuebingen); Dr Ahalya Viswanathan
(Max Planck Institute for Biological Cybernetics, Tuebingen)
Synopsis:
Cognitive Neuroscience depends on a proper interpretation of
brain imaging signals. Former interpretation has been simple, comparing number
of spiking neurons with average BOLD signals (i.e. Rees, Friston, Koch 2000,
Nat Neurosci.). What is the state-of-the art interpretation of BOLD
today? Results of Sirotin and Das (2009, Nature; and Devor et al. 2008, JNS)
have questioned the simple interpretation of BOLD by providing evidence for
BOLD-signal without neuronal activity. Is there a non-neuronal source for the
BOLD signal? Is there a brain activity signal that is missed by
electrophysiology? Does an activated region reflect activation in this region
or elsewhere (e.g. in the form of feedback)? How should state-of-the-art models
of neurovascular coupling affect the interpretation of brain imaging data?

Lauritzen 2005 Nature Reviews).
Scientific co-ordinator: Dr
Lars Muckli, CCNi.
