New research shows it's possible to use ultrasound waves to monitor activity in the human brain. Researchers implanted a material into the man's skull that allowed ultrasound waves to pass into his brain. After entering through an "acoustically transparent" window, these waves bounced off boundaries between tissues. The data allowed scientists to build a picture of what was going on in the man's brain, similar to how ultrasound scans can visualize a fetus in the womb.
