How do neuroglial cells respond to ultrasound induced cavitation?

Reactive astrocytes are known to play a vital role in the overall response of the brain during a traumatic brain injury (TBI). Modern studies have speculated the existence of cavitation in the skull during a TBI, which has alarming potential to cause detrimental damage. Previous studies have confirm...
