Rajesh Menon, University of Utah (IMAGE) University of Utah Caption University of Utah electrical and computer engineering associate professor Rajesh Menon holds a tiny surgical needle that can be used with a camera to take pictures of a mouse's brain cells. The process, which can be used by medical researchers, is much less invasive than earlier methods of examining a mouse brain. Menon believes the process ultimately could be used on humans for a less expensive, less invasive method of examining a patient's brain.
