*Abstract: * Recent advances in techniques for monitoring and perturbing
neural populations have greatly enhanced our ability to study circuits in
the brain. In particular, two-photon holographic optogenetics now enables
precise photostimulation of experimenter-specified groups of individual
neurons, while simultaneous two-photon calcium imaging enables the
measurement of ongoing and induced activity across the neural population.
Despite the enormous space of potential photostimulation patterns and the
time-consuming nature of photostimulation experiments, very little
algorithmic work has been done to determine the most effective
photostimulation patterns for identifying the neural population dynamics.
Here, I will discuss ongoing development of active learning techniques to
efficiently select which neurons to stimulate such that the resulting
neural responses will best inform a dynamical model of the neural
population activity.

*About VVTNS : Launched as the World Wide  Theoretical Neuroscience Seminar
(WWTNS) in November 2020 and renamed in homage to Carl van Vreeswijk in
Memoriam (April 20, 2022), Speakers have the occasion to talk about
theoretical aspects of their work which cannot be discussed in a setting
where the majority of the audience consists of experimentalists. The
seminars, **held on Wednesdays at 11 am ET,**  are 45-50 min long followed
by a discussion. The talks are recorded with authorization of the speaker
and are available to everybody on our YouTube channel.*
