Virtual Motor Control School

Dear Friends,

In these challenging times, which make traditional Conferences next to impossible, we have decided to organize a series of lectures under the umbrella of Virtual Motor Control School (VMCS). The purpose of VMCS is similar to that of the Motor Control Summer School (MCSS) that has been running annually over the past 17 years. We hope to provide a forum for in-depth discussions of a variety of exciting and contentious issues in the field of motor control in a format that encourages discussions, frequent interruptions of the speaker, digressions, etc.

Each 1.5-hr-long session will feature one speaker, a group of “active participants” (former and future speakers) and an unlimited number of viewers (“passive participants”). Only active participants will be able to interrupt the speaker, ask questions in real time, digress, etc. We will use Zoom as the main platform, and sessions will be streamed in real time on YouTube. 

Given the time zones, we plan all sessions to start at noon (Eastern US time zone), which corresponds to 9 a.m. in California and 5 – 7 p.m. in Europe (our apologies to colleagues in Asia, Australia, and New Zealand!). At this time, we plan to have two sessions each week, on Saturdays and Tuesdays.

Please confirm your registration by filling out the following form:
