Course focuses on neurotransmitters, transporters, receptors and intracellular signaling pathways that mediate chemical neurotransmission in the nervous system, with a secondary focus on the role of these neurochemical systems as pharmacological targets. Students attend lectures, read assigned scientific research articles, and present and critique these articles in class (2-3 presentations per student per semester). Students will also compose a final original perspective-type review paper based on a topic related to the course content, and give a final presentation based on their paper. Grading is determined by student presentations, an original final scientific review paper and participation in class discussions.
