You are cordially invited to the fifth season opening lecture of  the
online VVTNS series

*Karel Svoboda*
Allen Institute

 on the topic of

*Illuminating synaptic learning*

The lecture will be held on zoom on October 30, 2023, at *11:00 am EDT *

 This talk will *not* be recorded

*Abstract: *How do synapses in the middle of the brain know how to adjust
their weight to advance a behavioral goal (i.e. learning)? This is referred
to as the synaptic ‘credit assignment problem’. A large variety of synaptic
learning rules have been proposed, mainly in the context of artificial
neural networks. The most powerful learning rules (e.g. back-propagation of
error) are thought to be biologically implausible, whereas the widely
studied biological learning rules (Hebbian) are insufficient for
goal-directed learning. I will describe ongoing work focused on
understanding synaptic learning rules in the cortex in a brain-computer
interface task.

*About VVTNS : Founded as the World Wide Neuroscience Seminar (WWTNS) in
November 2020 and renamed in homage to Carl van Vreeswijk in Memoriam
(April 20, 2022), its aim is to be a platform to exchange ideas among
theoreticians. 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.*
