Transcranial Electric Stimulation
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 کاملAnimal Studies in the Field of Transcranial Electric Stimulation
Dozens of animal studies of transcranial direct current stimulation (tDCS) and transcranial alternating current stimulation (tACS) have provided insight into the cellular mechanism of stimulation. Biomarkers of tDCS/ tACS responses at the neurophysiological, behavioral, and molecular levels provide a basis to design clinical interventions that engage specifi c targets. This chapter provides a b...
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...
متن کاملMeasurements and models of electric fields in the in vivo human brain during transcranial electric stimulation
Transcranial electric stimulation aims to stimulate the brain by applying weak electrical currents at the scalp. However, the magnitude and spatial distribution of electric fields in the human brain are unknown. We measured electric potentials intracranially in ten epilepsy patients and estimated electric fields across the entire brain by leveraging calibrated current-flow models. When stimulat...
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...
