CMB Monday Seminar (Methods)- Rene Scheeringa
Electrophysiological correlates of the human BOLD signal Simultaneous recording of hemodynamic and electrophysiological signals in monkeys and cats suggest that the hemodynamic effects observed with fMRI are a reflection are more tightly coupled to changes in local field potential activity than to spike rate changes. Especially gamma band activity was found to be tightly related to hemodynamic changes. The question arises whether these observations in animals also translate to the BOLD signal in humans during performance of cognitive tasks. In the work presented here we used simultaneous recorded EEG and fMRI to investigate how task related EEG power changes in different frequency bands (theta, alpha, beta and gamma power) relate to the changes in the BOLD signal.

The CMB Monday Seminar is a forum for presenting ongoing and recent research projects, along with other things of interest. We will rotate among 4 different broad and partially overlapping topics: 1) Methods (mainly ERPs, but also others); 2) Vision (broadly construed); 3) Attention and related cognitive processes; 4) Disorders of Cognition (mainly schizophrenia). Most of the seminars will be presentations of ongoing or recently completed studies by grad students, postdocs, faculty, etc., with occasional visitors. The goal will be to go through experiments in detail, not to give a "finished product" talk and to provide a supportive environment for critically examining the research prior to writing it up or presenting it in a more formal talk.
