This may be of interest. Tony 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? (Logothetis 2008, Nature Reviews; Viswanathan and Freeman 2007, Nat Neurosci.; Lauritzen 2005 Nature Reviews). Scientific co-ordinator: Dr Lars Muckli, CCNi.
