Balancing the photon budget for optical neurophysiology

26 February 2021, 8:00 - 9:30 - Eastern Daylight Time (UTC - 04:00)

As genetically-encoded fluorescence indicators of calcium and membrane potential evolve and improve, optical methods advance to exploit their full potential for neurophysiology research. With so many choices, the neurophysiologist needs a systematic framework for comparing and predicting the performance of indicator/imaging system combinations. Dr. Foust will present such a framework for which the key figure of merit is the signal-to-noise ratio of the time-varying fluorescence signal. In this context I will also describe our efforts to boost photon budgets for membrane potential and calcium imaging with multi-focal two-photon and light-field imaging systems.
