Engineers Use Short Ultrasound Pulses to Reach Neurons Through Blood-Brain Barrier, Proceedings of the National Academy of Sciences Reveals


9/20/2011 7:51:47 AM

Columbia Engineering researchers have developed a new technique to reach neurons through the blood-brain barrier (BBB) and deliver drugs safely and noninvasively. Up until now, scientists have thought that long ultrasound pulses, which can inflict collateral damage, were required. But in this new study, the Columbia Engineering team show that extremely short pulses of ultrasound waves can open the blood-brain barrier -- with the added advantages of safety and uniform molecular delivery -- and that the molecule injected systemically could reach and highlight the targeted neurons noninvasively.
