Ultrasound Restores Memory to Mice with Alzheimer’s
Should we be concerned that ultrasound is capable of effecting changes in the brain?  Ultrasound is one of those "safe" medical operations that you don't think too much about because it's not chemical, radioactive, or built out of superconductors.<p>For example, 3D fetal ultrasounds bombard a baby but they are really only done out of pure vanity for parents.  They don't tell doctor's anything they don't already know from the boring standard ultrasound.
