Effect of dispersive conductivity and permittivity in volume conductor models of deep brain stimulation

Grant, Peadar F. ; Lowery, Madeleine M. (IEEE, 2010-10)

The aim of this study was to examine the effect of dispersive tissue properties on the volume-conducted voltage waveforms and volume of tissue activated during deep brain stimulation. Inhomogeneous finite-element models ...
Electric field distribution in a finite-volume head model of deep brain stimulation

Grant, Peadar F. ; Lowery, Madeleine M. (Elsevier, 2009-11)

This study presents a whole-head finite element model of deep brain stimulation to examine the effect of electrical grounding, the finite conducting volume of the head, and scalp, skull and cerebrospinal fluid layers. The ...
Simulation of cortico-basal ganglia oscillations and their suppression by closed loop deep brain stimulation

Grant, Peadar F. ; Lowery, Madeleine M. (IEEE, 2012-06-08)

A new model of deep brain stimulation is presented that integrates volume conduction effects with a neural model of pathological beta-band oscillations in the cortico-basal ganglia network. The model is used to test the ...
