 I thought that Paul did an exceptional job of covering the neurological system. This was extremely relevant to my students, and I now understand better why they behave as they do. This was a coplex system that was explained in a simplified manner that could be understood. I now know that everyones brain is different and that is why some students dont get along with others. This is really valuable information that I can take with me into the classroom and it will aid me in better understanding my students behavior. It does matter that neurons can generate action potentials. Signals along an axon is an action potential, and of course there are many different signals. All neurons give excitatory and inhibitory responses, therefore they are of equal importantance.
