About Us

About the Seminar

VVTNS  is a weekly digital seminar on Zoom targeting the theoretical neuroscience community. Created 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  are 45 min long followed by a discussion and are held on Wednesdays at 11 am ET. The talks are recorded with authorization of the speaker and are available to everybody on our YouTube channel.

 

To participate in the seminar you need to fill out a registration form after which you will

receive an email telling you how to connect.

Somatomotor to Higher Order Cognition -

 The Detailed Organization of the Human Cerebellum

The cerebellum is long known for its somatomotor functions. Recent evidence has converged to suggest that major portions of the human cerebellum are linked to cognitive and affective functions. In this talk, I will present new insights into the functional organization of the human cerebellum. Our findings reveal three distinct somatomotor representations, including a newly identified third map that is spatially dissociated from the two well-established body representations. Between these body representations, a large megacluster extending across Crus I/II was consistently found with subregions linked to higher-order cerebral association networks. Within this megacluster, specific regions responded to domain-flexible cognitive control, while juxtaposed regions differentially responded to language, social, and spatial/episodic task demands. Similarly organized clusters also exist in the caudate consistent with the presence of multiple basal ganglia–cerebellar–cerebral cortical circuits that maintain functional specialization across their entire distributed extents.

David Hansel

I am a theoretical neuroscientist at the National Center for Scientific Research in Paris, France and visiting professor at The Hebrew University in Jerusalem, Israel. I am mainly interested in the recurrent dynamics in the cortex and 

basal ganglia.

Ran Darshan

 I am a theoretical neuroscientist working at the Faculty of Medicine, the Sagol School of Neuroscience & the School of Physics and Astronomy at Tel Aviv University, Israel. I am interested in learning and dynamics of neural networks. My main goal is to achieve a mechanistic understanding of brain functions.
