Reading Preparation

Textbook assignment: Chapter 28: The Nervous System, sections 1 - 9.

Study Points

Web Lecture

Read the following weblecture before chat: The Human Nervous System.

Take notes on any questions you have, and be prepared to discuss the lecture in chat.

Study Activity

Perform the study activity below:

Use the HHMI click-and-learn activity to study the Electrical Activity of Neurons.

  • Click on the "Start Click and Learn" link. This activity has 13 slides, some of which have short animations.
  • What are Aplysia neurons? Why are they useful for studying neuron behavior?
  • How were the experiments conducted to gather information about Aplysia neurons?
  • What happens when low-voltage impulses are used to stimulate the neuron? What happens when the voltage reaches the threshold level for neuron response?
  • What is a radical reductionist approach to learning about neurons? How does this approach help us understand what is happening when a neuron receives input and "fires"?
