Lesson 4: How to build a neuron
This lesson is part of the unit:
After identifying the structures and functions of the brain, students move to the cellular and molecular levels to explore the neuron, the fundamental cellular building block of the nervous system. Students begin by discussing the versatile roles of the nervous system. The first activity in the lesson has student groups design their own neuron, or “Newron,” from scratch, based on knowledge learned in previous lessons and a series of guided questions. The students are then introduced to the anatomy and physiology of an actual mammalian neuron and asked to compare their design to a real neuron. Finally, the students are introduced to the ways in which traumatic brain injury manifests at the level of neurons and glial cells.
