Area of Science:

  • Neuroscience
  • Biomedical Engineering
  • Computational Modeling

Background:

  • Transcranial direct current stimulation (tDCS) uses electrode parameters like number, position, size, shape, and current to modulate brain activity.
  • Standard tDCS montages often rely on general guidelines, which may not fully capture complex current flow patterns.
  • Accurate current flow modeling is crucial for precise brain region targeting and understanding stimulation effects.

Purpose of the Study:

  • To highlight the increasing importance and advancements in computational forward models for tDCS.
  • To demonstrate how these models inform tDCS montage design and result interpretation.
  • To explore the application of computational models in customizing tDCS for specific populations and improving spatial targeting.
