From the paper - they don't use ultrasound itself to generate the effect, they use ultrasound to activate injected 'micro-bubbles' in the brain which disrupt the blood-brain barrier.
While an interesting hypothesis, it seems unlikely: one copy of each x-chromosome is deactivated in each cell, and this is done randomly in development.
