14.7 EEG fMRI

Figure 14.18: A schematic of a EEG-fMRI

This is a multimodal imaging technique where EEG and fMRI are used to study brain electrical activity in correlation with hemodynamic changes in the brain during activity.

The EEG nodes on the subject’s scalp measure brain activity; fMRI detects hemodynamic changes throughout the brain as a result of the BOLD effect.

EEG-fMRI allows us to measure both neuronal and hemodynamical activity.
