This training course will introduce you to the basic concepts of data acquisition and behavioural control using the Bonsai visual programming language.

Course Schedule

Monday Tuesday Wednesday Thursday Friday
Introduction to data acquisition Cameras, tracking, microcontrollers Real-time closed-loop experiments Operant behavior Final projects

Rapid-prototyping Systems Neuroscience with Bonsai

Session 1 - Introduction to data acquisition and behavioural control

  • How to measure almost anything with a computer. From quantities to bytes.
  • How to control almost anything with a computer. From bytes to effects.
  • What is a programming language, and why should you care? Introduction to Bonsai.
  • How to measure and control multiple things at the same time with one computer.
  • The impact of measurement and control technologies in the study of behaviour: past, present, and future.

Session 2 - Cameras, tracking and microcontrollers

  • Measuring behavior using video. From photons to pixels.
  • Recording real-time video from multiple cameras.
  • Real-time tracking of colored objects, moving objects and contrasting objects: the basic toolkit.
  • Measuring behavior using voltages and an Arduino.
  • A primer on data synchronization: on what frame did the light turn on?

Session 3 - Real-time closed-loop experimentation

  • What can we learn from closed-loop experiments?
  • Conditional effects. Triggering a stimulus based on video activity.
  • Continuous feedback. Modulate stimulus intensity with speed or distance.
  • Feedback stabilization. Record video centered around a moving object.
  • Measuring closed-loop latency.

Session 4 - Operant behavior tasks

  • Modeling trial sequences: state machines and events.
  • Driving state transitions with external inputs.
  • Choice, timeouts and conditional logic: the basic building blocks of reaction time, Go/No-Go and 2AFC tasks.
  • Combining real-time and non real-time logic for good measure.
  • Student project brainstorming

Session 5 - Final projects

  • Custom behavior tracking
  • Interactive visual stimulation
  • Audio acquisition and stimulation
  • Student project preparation and presentation
