Brief Trains of Closed-loop TMS Induce Controllable Power in FM-theta Oscillations

This study shows that brief TMS trains triggered at specific FM-theta phases can directionally modulate post-train FM-theta power, suggesting a causal role of oscillations in cognition.

Adaptive Bayesian localization of motor representation areas

This paper introduces an adaptive Bayesian method for localizing motor representation areas using TMS, reducing the number of stimuli needed for accurate localization.

Volume conductor models for magnetospinography

This study compares volume conductor models to determine their impact on magnetic field predictions from spinal cord current flow.

Multi-locus transcranial magnetic stimulation system for electronically targeted brain stimulation

The paper develops a multi-locus transcranial magnetic stimulation (mTMS) system that electronically controls the location and orientation of the electric field maximum in a cortical region.

Individual head models for estimating the TMS-induced electric field in rat brain

This study develops individual head models for rats using X-ray tomography to estimate TMS-induced electric fields and shows that head shape deviations significantly affect E-field distribution.

Comparison of beamformer implementations for MEG source localization

This study compares LCMV beamformer implementations across four MEG toolboxes, finding reliable source localization at typical SNR but differences in sensitivity to preprocessing parameters and SNR effects.

Requirements for coregistration accuracy in on-scalp MEG

This study quantifies the requirements for sensor coregistration accuracy in on-scalp MEG systems using simulations, finding that position errors have a larger impact than orientation errors.

Locating highly correlated sources from MEG with (recursive) (R)DS-MUSIC

This paper introduces DS-MUSIC and RDS-MUSIC methods for localizing brain sources from MEG data, showing they are robust to temporal correlations and accurate in simulations and real data.

Measuring MEG closer to the brain: Performance of on-scalp sensor arrays

This study compares the performance of on-scalp OPM arrays with a standard SQUID array in MEG, finding higher signal power and information capacity in OPMs.
