Cochlear output synchrony underlies brain oscillations as a marker for tinnitus - an OPM-MEG study

Rodrigo Donoso-San Martín, Stefan Fink, Christian Dobel, Elinor Riegger et autres

Abstract Despite its high prevalence and socioeconomic costs, the condition of tinnitus shares with related neuropsychiatric disorders the characteristic that, to this day, it cannot be cured. Two contradictory views of the origin of tinnitus (peripheral hyperexcitability and central brain oscillation changes …

Magnetic field camera for zero-field conditions

Ronja Rasser, Peter Koß, Svenja Knappe, K. Buse

We present a zero-field optically pumped magnetometer using a 300 µm-thick rubidium vapor cell, which is read out with a camera. The camera enables the measurement system to take more than 7 000 individual measurement points in a circle of 4 mm …

Measurement Equivalence of On-Scalp OPM-MEG and Cryogenic MEG for Auditory and Somatosensory Cortical Mapping Across Development

William Gaetz, George C O'Neill, Charlotte Birnbaum, Teresa Cheung et autres

Wearable optically pumped magnetometer magnetoencephalography (OPM-MEG) reduces sensor-to-cortex distance compared with conventional cryogenic SQUID-MEG, but whether the two technologies yield equivalent neurophysiological conclusions remains unclear. We recorded auditory and somatosensory evoked fields in 18 participants (10-45 years) using a 128-sensor FieldLine HEDscan …
