Question
Chapter 10, Problem 2CP
Summary Introduction
To review:
Transduction of sensory stimulus and coding of receptor potential.
Introduction:
Sensory stimuli induce sensory neurons to produce the generator potentials. The production of action potentials depends upon the magnitude of generator potential. Continuous firing of stimulus can lead to the generation of the action potential needed to respond to the stimuli. The response also depends upon the type of receptor being stimulated.
