Investigation of the changes in oscillatory power during task switching after mild traumatic brain injury.

Mild traumatic brain injury (mTBI) can cause persistent cognitive changes. These cognitive changes may be due to changes in neural communication. Task-switching is a cognitive control operation that may be susceptible to mTBI and is associated with oscillations in theta (4-7 Hz), alpha (8-13 Hz), and beta (14-30 Hz) ranges.
