Electroencephalography (EEG) systems measure the electrical field produced by neural activity in the brain in a non-invasive way, with temporal resolutions on the order of milliseconds. Over the last decade, researchers in two-person neuroscience have developped the use of EEG Hyperscanning equipment, which combines two such systems to measure the activity of two people’s brains simultaneously, producing time-synchronized measurements. This makes EEG Hyperscanning an excellent tool for investigating brain activity during dyadic interaction experiments, where timing is paramount to understanding the interaction dynamics.
The unit is equipped with a 2 x 96 channels EEG Hyperscanning system from BrainProducts, which we pair with several body signals measurements. This system is used during many of our dyadic interaction experiments for the systemic analysis of two-person brain-body-environment interactions.
