Selected omissions and capstone presentations: a new approach to student-centered integrative physiology education.

Here, we describe a pedagogical approach that combines didactics with active learning to facilitate integration across physiological systems in a team-taught, graduate-level physiology course. We covered the major physiological systems, with each system preceded by an overview of its evolution/ontogeny to provide a broader perspective. Lectures provided a framework for integration by giving examples of how each system interacted with systems that preceded and followed.

Wavelength and intensity dependence of retinal evoked responses using in vivo optic nerve recording.

We use a whole-animal model and wavelength-selective optical stimulation to investigate relationships between optical stimulus characteristics and neural signaling. Light-emitting diodes are used to selectively stimulate rod and cone pathways in Rana pipiens. A suction electrode is used to make in vivo measurements of the compound action potential from the optic nerve as the wavelength and intensity of the stimulus is varied.
