Effect of focused ultrasound stimulation at different ultrasonic power levels on the local field potential power spectrum

doi:10.1088/1674-1056/24/8/088704

Abstract

Local field potential (LFP) signals of the rat hippocampus were recorded under noninvasive focused ultrasound stimulation (FUS) with different ultrasonic powers. The LFP mean absolute power was calculated with the Welch algorithm at the delta, theta, alpha, beta, and gamma frequency bands. The experimental results demonstrate that the LFP mean absolute power at different frequency bands increases as the ultrasound power increases.
