*Abstract: *For decades dynamical systems theory played a pivotal role in
theoretical and computational neuroscience, as it links biophysical and
biochemical processes to neural computation. In fact, dynamical systems are
computationally universal. Rather than hand-crafting computational theories
of neural function based on dynamical systems, recent developments in
scientific machine learning (ML) and AI suggest that we may be able to
infer such dynamical-computational models directly from neurophysiological
and behavioral observations. This is called dynamical systems
reconstruction (DSR), the learning of generative surrogate models of the
underlying dynamics, including its long-term temporal and geometrical
properties, from time series data. In my talk I will cover recent ML/AI
architectures, training algorithms, and validation procedures for DSR. I
will discuss specifically how recent AI architectures for DSR can integrate
neuroscience data from multiple modalities (like multiple single-unit
recordings and behavioral choices), across diverse time scales, and across
many different animals and task designs, into a joint DSR model. This
provides first steps toward dynamical systems based AI foundation models
for neuroscience.

*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.*
