 on the topic of

Properties of memory networks with excitatory-inhibitory assemblies


The lecture will be held on zoom on Wednesday, December 18, 2024, at *11:00
am EST *

*Abstract: * Classical views suggest that memories are stored in assemblies
of excitatory neurons that become strongly interconnected during learning.
However, recent experimental and theoretical results have challenged this
view, leading to the hypothesis that memories are encoded in assemblies
containing both excitatory (E) and inhibitory (I) neurons. Understanding
the effects of these E-I assemblies on memory function is therefore
essential. Using a biologically constrained model of an olfactory memory
network, I will first describe how introducing E-I assemblies reorganizes
odor-evoked activity patterns in neural state space. Indeed, the “geometry”
of neural activity provides valuable insights about the computational
properties of neural networks. I will then describe the behavior of
networks with E-I assemblies upon partial manipulation of inhibitory
neurons. Finally, I will discuss recent experimental data supporting
predictions of the model.

*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.*
