Despite being diminutive in size, iChips have the potential to make big impacts on drug development and medical treatment testing. Lawrence Livermore National Lab is replicating the human body on a miniature scale, specifically focusing on brain physiology. Capturing human physiology outside the body allows scientists to probe and understand the human body without using human subjects. Staff scientist Elizabeth Wheeler describes how her group is using biology, 3D bioprinting, microchips and other technology to recreate human physiology outside the body. Recorded on 02/13/2016.
