Science at EGI

From the early days in building research EEG systems, EGI has been known for scientists building tools for scientists. Although the range and complexity of both research and medical customers has expanded, we have worked to maintain this direct presence of science and medical attention to each product and support function of the company.

EGI’s science team has a wide range of skills, including cognitive neuroscience, neuropsychology, clinical neurophysiology, education, psychopathology, computational physics, computational science, and statistics. See a list of publications by the EGI science team.
