1. Unit 3

2.  Seminar - Attend the seminar or complete the option 2 seminar assignment  Discussion questions address the following: 1) electrochemical and chemical components affecting our thoughts, behaviors, and emotions; and 2) what happens when parts of the brain fail. Remember to provide 150 minimum word responses to both questions and provide 2 fifty word responses to students. To receive full credit, post responses by 11:59pm EST on Tuesday.
