Details of Nerve Impulse Part I
This video program deals with extracellular recording of the compound action potential in the frog sciatic nerve preparation. Part I of the tape provides background information for an understanding of the experimental information provided in Part ll.
Part one of this video program begins with a consideration of the general structure of a nerve cell. The tape then introduces the terms polarization, depolarization and repolarization and discusses the origin of the resting membrane potential and action potential. This is followed by a discussion of the recording of the diphasic compound action potential from the bullfrog sciatic nerve.
Part one concludes with a demonstration of the dissection and excision of the sciatic nerve from the bullfrog.
