Connectionists: Open Lab Online workshops on Bonsai – July sessions now open

[Mateusz Kostecki]

Hello,

Good morning everyone,
We are happy to announce two new upcoming *Open Lab Online workshops on
Bonsai* this July.
*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 are part of our *3-module online course of increasing
difficulty*, designed to progressively introduce participants to Bonsai and
its practical applications.
*Introduction to Bonsai (Module I)*
*July 13, 2026 | 16:00–17:00 CEST (UTC+2)*
In this first module, participants will be introduced to the basics of
Bonsai — its logic, syntax, and potential applications. The workshop will
also cover animal tracking, ROI detection, closed-loop paradigms, and basic
logical operations.
*Instructor:* Jagoda Nawrocka, University of Warsaw
*Fee:* EUR 10, with fee waivers available upon request
*Registration:*

*Introduction to Bonsai (Module II)*
*July 16, 2026 | 16:00–17:30 CEST (UTC+2)*
In this second module, we will move on to more advanced aspects of working
with Bonsai. The workshop will introduce the *BonVision* library for visual
stimulus presentation and VR applications, and explore how to combine
multiple data streams to build more complex and interactive behavioral
paradigms. We will also cover behavioral subjects and variable control
across different branches of a workflow.
*Instructor:* Mateusz Kostecki, Heidelberg University
*Fee:* EUR 10, with fee waivers available upon request
*Registration:*

We would also like to warmly invite you to join our *Open Lab Online
Discord*, which serves as a space for discussion, exchange, and community
around open tools and methods. Important workshop updates and information
are also shared there.
If you have any questions, feel free to contact us at
*openlab at nencki.edu.pl* <openlab at nencki.edu.pl> or reach out to us on
*Discord*.
Best wishes,
The Open Lab Online team
