"A Diamond Magnetic Microscope for Neuroscience" is the title of the talk to be presented by Jennifer Schloss ’11, PhD candidate in physics at MIT.
Abstract: Nitrogen-vacancy (NV) centers in diamond are atomic-scale impurities that can detect weak or nanoscale magnetic fields under ambient conditions. In this talk I will illustrate how we harness NV centers to detect the fleeting magnetic fields produced by individual firing neurons.
I will describe how we built a device that achieves record broadband magnetic field sensitivity and all-optical detection without causing any damage to biological samples. Finally, I will discuss recent advances that open the door to noninvasive imaging of functional activity in neuronal circuits using these quantum defects in diamond.
A reception for Jenny begins at 4:10 p.m. in the Anderson Lounge, Wright Lab, second floor.
