[visionlist] Open Lab Online workshops on Bonsai – Module I sessions now open

[Mateusz Kostecki]

Hello!
We are happy to announce the *first Open Lab Online workshops *on *Bonsai*.
*Bonsai* is an open-source reactive programming language that is
particularly useful for modern behavioral neuroscience experiments. It
allows users to synchronize multiple data streams, precisely deliver
stimuli, and run experiments in closed-loop settings, while integrating
signals and devices from different systems. From calcium imaging and sound
recordings to sensors, feeders, motors, and stimulus delivery systems,
Bonsai offers a flexible and powerful way to build experimental workflows.
These workshops correspond to *Module I* of a *3-module online course of
increasing difficulty*. In this first module, participants will be
introduced to the basics of Bonsai — its logic, core principles, and
potential applications. The workshop will also cover how to track animals
during experiments, detect their presence in ROIs, run simple closed-loop
paradigms, and perform basic logical operations.
To make participation easier across schedules and time zones, we are
offering *two alternative sessions of the same workshop*:
*Session 1:* May 8, 2026, 10:00–12:00 CEST (UTC+2)
https://nenckiopenlab.org/event/introduction-to-bonsai-module-i/
*Session 2:* May 18, 2026, 16:00–18:00 CEST (UTC+2)
https://nenckiopenlab.org/event/introduction-to-bonsai-module-i-2/
*Requirements:* no prior programming experience is needed. A *Windows
computer* and a *webcam* are required.
*Workshop fee:* EUR 10
*Fee waivers are available upon request.*
*Instructor:* Mateusz Kostecki, Heidelberg University
We also warmly invite you to join our *Open Lab Online Discord*, which is a
space for discussion, exchange, and community around open tools and
methods. All important workshop information and updates will also be shared
there.
