Electrical Language of Cells

1 Course Unit

This course introduces students to high-speed electro-chemical signaling mec hanisms that occur in nerve and other excitable cells during normal activity. Topics considered in substantial detail include: a)a basic description of the passive and active membrane electrical properties; b)the molecular architecture and functional role of ion channels in cell signaling; c)the role of the calcium ion as an umbiquitous chemical mesenger, with applications to neuro-secretion; d)excitatory and inhibitory transmission in the central nervous sytem; e) sensory transduction, as illustrated by the visual, olfactory, and autitory pathways. The course assumes a standard background in cell biology, as well as basic concepts from college physics and college calculus. Fall 1 Course Unit
