Electric field estimation in deep transcranial magnetic stimulation Academic Article uri icon

abstract

  • Methods We used two human models of the Virtual Family [Christ et al., 2010] based on high resolution MRI of healthy volunteers (a 26-years-old female and a 34-years-old male). The H1 coil was modelled as current paths according to its real complex winding patterns and placed 5.5 cm anteriorly the left hemisphere motor cortex of the right hand abductor pollicis brevis. Moreover, the figure-of-8 coil was placed alternatively on the right and the left dorsolateral prefrontal cortex to compare the effect of the stimulation with the H1 coil in both hemispheres. For all simulations we used a current pulse with a frequency content of 5 kHz and a current intensity adjusted to obtain 120% of the hand motor threshold. Simulations were conducted using the magneto quasi-static low-frequency solver of the simulation platform SEMCAD X. Results The H1 coil induced electric field with higher amplitude and …
