Learning Fear: Exploring Pavlovian Conditioning and Neural Pathways
This diagram shows the development of Pavlov’s experiments and how they can condition a dog to salivate just to a tone without any primary stimulus.Copyright https://cleverism.com/how-the-conditioned-stimulus-works-in-classical-conditioning/
Students build on their understanding of how the brain uses circuits to respond to external stimuli, learning about Pavlovian conditioning through the lens of neural circuits. By exploring Pavlov’s dog experiment, students connect their knowledge of neurons and neural pathways to understand how animals, including humans, learn through association. The lesson emphasizes the concept of learning and synaptic plasticity, which are key to understanding how neural circuits control behavior. Students engage in hands-on activities, such as drawing circuits, discussing the Pavlov experiment, and using tools such as Google Colab to explore fear learning and the role of the amygdala. With the help of videos and group discussions, they examine the neural pathways involved in both reward and fear conditioning.
Neural engineers, biomedical engineers, and cognitive engineers apply principles from both biology and engineering to design, analyze, and optimize systems related to the brain and neural circuits. Neural engineers focus on developing technologies to interact with the brain, such as neural interfaces and brain-computer interfaces. Biomedical engineers work on systems that interface with biological systems, such as creating devices or tools for studying brain activity. Cognitive engineers, particularly those in fields like human-computer interaction, apply knowledge of the brain's response to stimuli to design systems or tools that adapt based on learning and behavior. These engineers often use similar principles—such as circuits, systems modeling, and adaptation—to create technologies that can respond to biological or cognitive inputs.
After this activity, students should be able to:
- Describe the basic principles of classical conditioning, such as how an animal can learn to associate a stimulus (e.g., a tone) with a reward (food) or a punishment (foot shock) after repeated exposure.
- Describe how neurons and neural circuits change to create learned associations in both the dog and the mouse experiments.
- Predict the outcome of a different stimulus-response pairing by applying their understanding of classical conditioning.
