4D-EEG: a new tool to investigate the spatial and temporal activity patterns in the brain

Themes: Life Science & Health, Robotics

Proof of principle

A TRL is a measure to indicate the matureness of a developing technology. When an innovative idea is discovered it is often not directly suitable for application. Usually such novel idea is subjected to further experimentation, testing and prototyping before it can be implemented. The image below shows how to read TRL’s to categorise the innovative ideas.

Patient-centered rehabilitation maximises post-stroke functional recovery. Prognostic models help adjusting rehabilitation strategies. 4D-EEG is a new tool for monitoring dynamic cortical plasticity during stroke recovery with high temporal-spatial resolution.


Robotic manipulators apply mechanical perturbations to the sensorimotor system. High-density electroencephalogram records electrical potentials from the scalp. Advanced source localisation and system identification algorithms describe the underlying neurophysiological system.


We have developed methods for neuromuscular system identification, and are improving source localisation algorithms. Results of an ongoing longitudinal study will be available within three years.
