MRI-Compatible Carbon Glass Brain Electrode

Nov-24-19 An innovative brain implant made from glass carbon instead of metal is MRI compatible and more durable than standard materials.

Electrodes implanted in the brain are useful for controlling seizures, but they can hinder MRI evaluations by generating dangerous heat then they vibrate in response to exposure to a magnetic field. As a safer alternative, researchers from KIT and San Diego State replaced the typical thin film of platinum or iridium oxide with a glassy carbon material that will not become magnetized. As a bonus, the glassy carbon electrode can also read the brain’s chemical signals, offering another mode of study.
