PHARMACOLOGY TRACK GRADUATE PROGRAM

PHAR 5091.008

 

Course Name: Neural Substrates of Regulatory Behaviors: Peptides and Monoamines

 

Course Director: Dr. Tom Cunningham

 

Course Content: Curt Richter identified behavior as a critical component for homeostasis in his pioneering work on sodium appetite. This course will review current studies that have identified peptide (angiotensin, vasopressin and oxytocin) and monoamine (norepinprhine, 5-HT, and dopamine) transmitter systems involved in water intake and sodium appetite.

 

Grading: Students will write a 1-2 paragraph summary for each paper on the reading list and be expected to participate in class discussions. At the end of class, they will be required to turn in a 5-10 page paper describing an original experiment based on the reading list and class discussions. The topic for the paper will be approved by the instructor. Grades will be assigned based on paper summaries (30%), class participation (30%), and the research paper (40%) using an A-F scale.

 

Pre-requisites: Consent of instructor

 

Credit Hours: 1 credit

 

Papers: (1-8, 10) (9)
