This paper designs and validates focal-deep TMS (fdTMS) coils that improve spatial targeting precision and depth of electric field stimulation compared to conventional figure-8 coils.

This study investigates how the orientation of TMS-induced electric fields affects short-interval intracortical inhibition and facilitation in the motor cortex, finding optimal orientations for maximizing MEP suppression and facilitation.

This study compares the stimulation strength, perceived loudness, and EEG response between a quiet TMS coil (qTMS-DCC) and a conventional TMS coil, finding the qTMS-DCC is quieter and produces smaller auditory-evoked potentials.

This paper develops an electronic TMS transducer for precise E-field orientation control and validates a model of neuronal excitability orientation selectivity.

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.

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.

The paper compares the sound levels of seven TMS coils at matched stimulation strength, finding significant variation in sound pressure levels and recommending hearing protection.

The paper presents computational methods for real-time calculation of TMS-induced electric fields in a realistic head model including cerebrospinal fluid.

This paper shows that neglecting head size in TMS modeling can overestimate stimulus intensity in rat brains by 5-8 times and suggests using simple spherical models for better estimation.
