*Abstract: *While anatomical connectivity changes slowly through synaptic
learning, the functional connectivity of neurons changes rapidly with
ongoing activity of neurons and their functional interactions. Functional
networks of neurons and neural populations reflect how their interactions
change with behaviors, stimulus types, and internal states. Therefore, the
information propagation across a network can be analyzed through the
varying topological properties of the functional networks. Our study
investigates the functional networks of the visual cortex at both the
single-cell and population levels. Our analyses of functional connectivity
of single neurons, constructed from spiking activity in neural populations
of the visual cortex, reveal local and global network structures shaped by
stimulus complexity. In addition, we propose a new method for inferring
functional interactions between neural populations that preserves
biologically constrained anatomical connectivity and signs. Applying our
method to 2-photon data from the mouse visual cortex, we uncover functional
interactions between cell types and cortical layers, suggesting distinct
pathways for processing expected and unexpected visual information.

*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.*
