A perturbative approach to understand retinal computations

*Abstract: *A major challenge in sensory systems is to understand how
neurons extract information from the natural environment. Models derived
from their responses to artificial stimuli often have a hard time to
generalize and predict responses to natural scenes. However, models
directly learned on the responses to natural scenes can be hard to
interpret. To address this issue, we have recently developed an approach
where we add small perturbations to natural scenes and measure how these
perturbations change neuronal responses, to better understand the features
extracted by sensory neurons. I will show several applications of this
approach in the retina, and how it allowed us to uncover non-linear
computations performed by ganglion cells, the retinal output.
*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.*
