Visualization of Electromagnetic Activity (Sleep, Epilepsy)


Key Investigators

  • BWH: Padma Sundaram

Objective

We are interested in visualizing electromagnetic activity in the brain using MR imaging with concurrent EEG. We are particularly interested in inspecting epileptic foci and sleeping individuals.

Approach, Plan

Data currently acquired:

  • Rest-state fMRI and concurrent EEG (normal healthy volunteer)
  • EEG of a sleeping individual (no MRI yet, but data covers 8 pm to 10 am and all sleep stages)

Progress
