Longitudinal Functional Assessment of Brain Injury Induced by High-Intensity Ultrasound Pulse Sequences.

At 24 hours post HIFU, both sham and HIFU exposed animals showed a trend towards reduction in low frequency oscillatory activity (relative δ; 1–4 Hz) and an increase alpha frequency activity (relative α; 8–13 Hz), leading to reductions in the δ/α and δ/β power ratios (Figs 4 and S1 ).

In contrast to changes in activity of the contralateral hemisphere, the ipsilateral hemisphere of HIFU-treated animals demonstrated higher δ oscillations, but lower γ frequency oscillations, compared to sham animals (Figs 5A and S4 ), though these did not reach statistical significance.
