Extracellular Electrophysiology Acquisition is a Cajal NeuroKit. NeuroKits are hybrid courses that combine online lectures about fundamentals and advanced neuroscience topics, with hands-on and physical experiments.
Researchers from all over the world can participate thanks to the course material sent by post in a kit box containing all the tools needed to follow the online course.
Any data we collect has been shaped by the system we used to record it. Understanding the tools involved in data acquisition gives you the confidence to make informed experimental design choices, and the freedom to combine and try new approaches while building your dream setup.
In this course, we will develop your understanding of electrophysiology data acquisition. In terms of hardware, you will learn how acquisition systems can amplify tiny signals and filter out noise. You’ll test this understanding by building your own system to measure muscle and heart signals. In software, you will encounter synchronisation considerations, as we add incoming datastreams and build an increasingly complex experimental design.
Don’t be discouraged if you secretly panic at the mention of capacitance, this course starts from the very basics. Advanced students can make the final project as challenging as they like.
Designed by Open Ephys and Open Ephys Production Site, this course will have an open-source flavour and encourage you to try new ideas, share your insights, and connect with the open-source community.
What will you learn?
By the end of the course, you will:
be familiar with the electronic building blocks of acquisition systems
be able to model and build circuits to amplify and filter incoming signals
be able to use the Bonsai programming language to stream data and run closed-loop experiments with multiple datastreams
