Optimizing Parameters of Low-Intensity Focused Ultrasound for Cortical Modulation in Stroke Patients

Brain stimulation using ultrasonic stimulation in a sequence of increasing intensity (sham, 1 W/CM2, 2 W/CM2, 4 W/CM2, 6 W/CM2, 8 W/CM2)

Brain stimulation using ultrasonic stimulation of intensity level determined from intervention 1 at progressively increasing frequency levels (0.35 MHz; 0.5 MHz; 0.75 MHz, 1.0 MHz and 1.5 MHz)
