Eccentric figure-eight coils for transcranial magnetic stimulation.
Previously we proposed an eccentric figure-eight coil that can cause threshold stimulation in the brain at lower driving currents. In this study, we performed numerical simulations and magnetic stimulations to healthy subjects for evaluating the advantages of the eccentric coil. The simulations were performed using a simplified spherical brain model and a realistic human brain model. We found t...
متن کاملElectric field properties of two commercial figure-8 coils in TMS: calculation of focality and efficiency.
OBJECTIVE To compare two commonly used TMS coils, namely the Medtronic MC-B70 double coil and the Magstim 70 mm double coil, with respect to their electric field distributions induced on the cortex. METHODS Electric field properties are calculated on a hemisphere representing the cortex using a spherical head model. The coil designs are characterised using several parameters, such as focality...
متن کاملFast multigrid-based computation of the induced electric field for transcranial magnetic stimulation.
In transcranial magnetic stimulation (TMS), the distribution of the induced electric field, and the affected brain areas, depends on the position of the stimulation coil and the individual geometry of the head and brain. The distribution of the induced electric field in realistic anatomies can be modelled using computational methods. However, existing computational methods for accurately determ...

Asif Rahman, Davide Reato, Abhishek Datta, Lucas Parra, Marom Bikson (CUNY) Synaptic pathway and orientation specific modulation of neuronal excitability by weak direct current Transcranial direct current stimulation, a clinical technique explored for noninvasive neuromodulation, is thought to induce polarity-specific lasting change in cortical excitability. However, the mechanisms of DC stimul...
متن کاملDeterminants of the electric field during transcranial direct current stimulation
Transcranial direct current stimulation (tDCS) causes a complex spatial distribution of the electric current flow in the head which hampers the accurate localization of the stimulated brain areas. In this study we show how various anatomical features systematically shape the electric field distribution in the brain during tDCS. We constructed anatomically realistic finite element (FEM) models o...
