In this video I explain and show the action potential of the Venus Fly Trap, a carnivorous plant. Even though plants don't have neurons (!), the mechanisms that cause this remarkable plant to close its leaves around prey are remarkably similar to the action potential of neurons in the animal nervous system.

[https://www.buymeacoffee.com/cogsci] In this video, I demonstrate list comprehensions in Python. This is a way to build list objects with a single expression. The notebook for this video is available at https://osf.io/pyk7w/. For more tutorials, visit https://python.cogsci.nl/.")

In this video, the second of a two-part series about object-oriented programming in Python, I show how to create your own class, including an initialization function, a method, and a property. (For more tutorials, see https://python.cogsci.nl/. For the Rapunzel IDE, see https://rapunzel.cogsci.nl/)")

(See https://python.cogsci.nl for code and written tutorials.) This is the first of a series of video tutorials about deep learning with Keras in Python. Here I introduce the basic concepts and terminology related to deep learning. I also describe how artificial neural networks compare to biological neural networks, such as our brains. Finally, I introduce TensorFlow and Keras, the Python libraries that we will use in later tutorials.")
