Karl Mendoza, a master’s student in biology, works on neural anatomy in the lab of John Griffin, Class of 2012 Associate Professor of Biology and director of the neuroscience program. The two are working to perfect a gold nanoprobe staining system designed by Mendoza. Adapting a probe used in cancer treatment, their aim is to develop a tool to label specific individual neurons. “The goal is that we’ll be able to go back and record from those cells, so we’ll be able to trace where they connect to and we’ll know their physiology,” Griffin said.
