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.

The effect of sensor-to-source distance on magnetic neuromuscular signals

Scientific Reports
Magnetomyography (MMG) can be used as a contactless modality to study the neuromuscular system. On the one hand, being contactless is a practical advantage as there is no need to prepare skin or attach electrodes as in electromyography (EMG).

Magnetic particle imaging using a multi-axis optically pumped magnetometer and multiple flux transformers

Sensing and Bio-Sensing Research
Biofunctionalized magnetic nanoparticles (MNPs) have been widely studied for biomedical applications, including magnetic particle imaging (MPI), which is a promising diagnostic technique for cancer imaging.

Spectral analysis of spin noise in an optically spin-polarized stochastic Bloch equation driven by noisy magnetic fields

AIP Advances
We theoretically analyze an optically spin-polarized collection of atoms, which serves as a basis for atomic sensors. Assuming that the intrinsic atomic spin projection noise is negligible, we provide the closed-form autocorrelation function and the ...
