Spring, odd-numbered years (1/2 semester course; 1/2 credit)
Roland Kallen, M.D., Ph.D., email@example.com

Course goals: Examine the structure-function aspects of ion channels (especially channel gating and ion selectivity) and investigate examples of mutations in channels that result in inherited diseases.
Format: Assignment and discussion of hallmark papers in the field, student presentations and critical discussion with an occasional lecture, there will be some homework problems and a final exam.
