Electroencephalography (EEG)

The coordinated activity of large neuronal ensembles can be measured at the scalp surface with electroencephalography (EEG), providing a convenient way to measure brain activity for research and clinical purposes. Recording EEG activity is completely safe and painless. EEG yields temporal resolution of the order of the millisecond, and can be integrated with during functional magnetic resonance imaging (fMRI) for multimodal imaging investigations.
