Is It the Right Way to Measure Neurons?

Welcome back to Neurotech Pub!

This episode is one of a two part series on optical methods for recording and stimulating neural activity. Our guests on this episode are Elizabeth Hillman, PhD,  Mark Schnitzer, PhD, and Jacob Robinson, PhD. So far, our technical dives have focused mainly on direct electrical recording and stimulation of neural activity, but in this episode we deep dive into advantages that all-optical interfaces might have over electrical interfaces, and the challenges in developing them. 

In addition, we talk about running highly collaborative, interdisciplinary projects that span traditional physics and engineering with biology, a theme that is ever-present in neurotech and is also highlighted in part two of this series. 

Cheers!
