Monthly conference (PhD seminar) – Peter Scheiffele

2 December 2022 / 11:30 - 12:30

Peter Scheiffele
Biozentrum, University of Basel, Switzerland

Invited by Elena Baz Badillo (Thoumine’s team)


Molecular Mechanisms of Neuronal Circuit Development and Plasticity


Neuronal circuits represent an impressive example of a complex, highly organized system. Circuit assembly and plasticity rely on cellular recognition events during development that specify synaptic connections and the exchange of signals that modify synapse density in the adult. We are testing the hypothesis that alternative RNA splicing is a central mechanism for the amplification of molecular diversity that drives synapse specification in mice.  I will discuss recent work from the lab on synapse-specific functions of individual splice variants of synaptic proteins in synapse specification and our efforts on examining how spontaneous sensory experience modifies alternative splicing programs in developing cortical networks.  In the second part of the talk, I will discuss recent findings on an unexpected role for a developmental morphogen in controlling excitation-inhibition balance in mature cortical circuits.
