Research Summary: 

Matthew Brookes, PhD, is internationally acclaimed for his work on human brain imaging, and in particular for his role in developing a new type of wearable magnetoencephalography (MEG) device. MEG measures tiny magnetic fields generated by the electrical currents that flow through neurons in the brain. These neuronal signals enable direct mapping of brain networks on a millisecond-by-millisecond basis as they form and dissolve to mediate sensory and cognitive function.

Although their potential had been recognized for decades, traditional MEG scanners have found limited applications. They are large, cumbersome, and very expensive because they rely on superconducting sensors, which need to be cooled to extremely low temperatures (-269°C) to operate. They also require the subject to remain still for long periods during a scan, preventing their use in young children or people in active motion.

Brookes and his team have created a step-change in MEG technology by devising a wearable, helmet-like scanner that can acquire data while a subject moves. This was enabled by a novel type of quantum optical sensor. The new sensors measure magnetic fields without the need for low temperatures, and at a much lower cost than superconducting sensors. As these sensors are placed much closer to the brain, his helmet-like MEG scanners achieve dramatically better sensitivity and spatial resolution compared to traditional technology. Brookes has successfully used these MEG instruments to scan young children, adults playing sports, and patients with neurological disorders such as epilepsy, demonstrating their massive potential for both fundamental and translational neuroscientific research. He has founded a company—Cerca Magnetics Limited—to commercialize his technology, with clients across Europe, North America, and Asia including some of the world’s largest children’s hospitals.

“For me, understanding the human brain and the many disorders that affect it is one of the greatest scientific puzzles. That the magic of quantum physics can allow us to watch the brain at work, and provide pieces of that puzzle, is truly remarkable!”
