TITLE: Wearable magnetoencephalography
Abstract:
Conventional MEG systems employ superconducting sensors housed inside a liquid helium dewar. Systems are large, expensive, and the cryocooled sensors are fixed in position. Consequently, subjects must remain still during measurements to avoid loss of data quality, limiting utility in some subject cohorts, particularly children and adults with movement disorders. We have developed a wearable MEG system using QuSpin optically-pumped magnetometers (OPMs) which can be mounted on the scalp and if background fields are appropriately nulled, MEG data can be acquired even when individuals make natural head motions. This system provides a more comfortable experience than in traditional neuroimaging systems, like MRI. Using our system we have measured brain activity arising from natural tasks: these include bouncing a ping-pong ball on a bat; measurements in children as young as 2 years old; language lateralisation measurements to aid pre-surgical planning; experiments using an Occulus Rift virtual reality headset to provide an immersive and realistic environment; investigations of motor learning and measurements of deep brain structures such as the cerebellum. In this talk I will present the development of the system and outline key results.
ALL ARE WELCOME.
