The Nervous System II (Synapses):

 

• Insert the Nervous System CD-ROM (Action Potential) from the Interactive Physiology Series of CD-ROMs.

• This week - work your way through the five sections of the CD-ROM. Pay particular attention to the key terms listed below.

• Next week - Prepare a 3-5 minute presentation to the class. This oral presentation should include:

a) a general introduction to the particular area that you are going to present

b) a demonstration, using the CD-ROM, of the particular process that you think is particularly well illustrated.

c) How would you change the specific part(s) of the CD-ROM that you are demonstrating?

- What additional info would you like to see added?

- What information is just a distraction?
