Employing EEG, behavioral measures and subjective evaluation our group investigates potentially clinically applicable brain responses - both during the resting-state and in response to external sensory stimulation. We evaluate how subjects' traits and states, task they perform and stimulation we use affects brain activity.
We use various approaches (i.e. classical P300, P50, Go/NoGo, MMN), however, our special focus is on the brains' ability to entrain measured as steady-state responses (SSRs): we evaluate brain's entrainment to external stimulation (auditory, visual, somatosensory ) and factors that modulate it.
This knowledge is important in order to objectively collect data and interpret obtained results both in healthy and diseased populations.
