Concurrent spinal and brain imaging with optically pumped magnetometers

Journal of Neuroscience Methods
The spinal cord and its interactions with the brain are fundamental for movement control and somatosensation. However, brain and spinal electrophysiology in humans have largely been treated as distinct enterprises, in part due to the relative inaccessibility of the spinal cord.

Evaluating task-evoked neurovascular coupling using integrated OPM-MEG and fNIRS imaging

NeuroImage
The characterization of neurovascular coupling (NVC) is essential for understanding brain physiology, and it is the basis of functional magnetic resonance imaging.

OPM-MEG reveals dynamics of beta bursts underlying attentional processes in sensory cortex

Scientific Reports
Human brain electrophysiology is dominated by rhythmic activity—neural oscillations—which play an important role in coordinating brain function. In the somatosensory cortices, the dominant oscillations occur in the beta (13–30 Hz) band and are thought to
