简要总结
This study is investigating a new method of brain imaging - transcranial functional ultrasound (tFUS). We are comparing the imaging capabilities with functional magnetic resonance imaging (fMRI).
详细描述
A battery of tasks will be performed under two imaging conditions. Magnetic Resonance Imaging and transcranial functional ultrasound imaging. Tasks include a breath hold task, an e-stim task, and low-intensity focused ultrasound neuromod.
