Video recordings in MEG and the Helsinki VideoMEG Project

Our project focuses on video-MEG—augmenting MEG procedure with simultaneous synchronized video recordings of the participant. Video recordings provide a rich source of information about the participant’s behavior during the experiment; capturing and analyzing this information can significantly facilitate the interpretation of the MEG signals.

In particular, our research focuses on video-MEG recordings of epilepsy patients; we believe (and we have scientific evidence supporting that belief)  that video is of critical importance for correct interpretation of epilepsy patients’ MEG data.

Our work includes:
1. Developing instrumentation for recording video and audio from the participant during an MEG examination.
2. Developing tools for analyzing the resulting audiovisual recordings, in particular using machine vision techniques, such as optical flow estimation.
In addition, we work on making video-MEG accessible to any MEG laboratory in the world by sharing our developments through the Helsinki VideoMEG Project.
