Unformatted text preview: 2. Differentiate between the coding properties of graded potentials and action potentials. 3. Rationalize the necessity for adaptation and sensitivity control in terms of cellular processes and stimulus dynamic range. III. Sample Problems: 1. How is intensity encoded as a graded potential? 2. How is intensity encoded as action potentials? 3. What two ways control sensitivity in the Pacinian corpuscle? file:///C|/WINWORD/COURSES/31107/Lec12-07.htm8/15/2007 10:16:57 AM...
