UNDERSTANDING PHINEAS Building a 3D Neural Network

Understanding Phineas Gage Discuss with your lab group & write in your journal: Phineas Gage Video Link What was Phineas like before the accident? What stayed the same for Phineas after the accident? What changed? What region of his brain was most affected by the accident? What information did his injury provide to neuroscientists?

Group Review Questions AFTER building a class graph for our model… Discuss the following with your group… 1. What actions are controlled in this region of the brain? 2. How do the neurons communicate with each other? 3. Do the neurons touch each other to communicate? 4. Which neurons are the most important? Explain why.

Connecting the Regions NEXT we will connect the regions of our lobe to other lobes and watch this video: View Path of Tampering Rod INSTRUCTIONS: Sketch a diagram of the "Class" neural network in your journal. Correctly label each of the nodes in your diagram. Label your diagram & identify the primary function of your class lobe. Identify the most important nodes in your neural network.

Evidence of Understanding What happens to each lobe when it’s injured? TBI Video Link In your journal…answer the following questions: Identify the most important nodes in the other regions of the brain. Use the brain box model to explain the difference in Phineas Gage after the accident. How might damage in one region affect other connected regions? Are there alternative pathways for action potentials to travel in the class model? What is an advantage of these alternative paths?
