Assessing Methods for Imaging Activity in Multiple Cell Types Simultaneously

PROJECT DESCRIPTION
Recent advances have produced genetically encoded proteins that allow researchers to measure neural activity using fluorescent indicators. We are working to improve these methods to allow simultaneous imaging of multiple types of neurons, with cellular resolution. We are using two approaches. In the transgenic approach, we take advantage of available transgenic animals. In the viral approach, we introduce genetically encoded indicators using viruses. Our goal is to compare the efficacy of the transgenic and viral approaches. Students working on this project will learn about neuroscience, molecular biology, inmmunohistochemistry, microscopy, and image processing.
