If the sensory nerves all use exactly the same form of communication (a neural impulse), how, then, do we experience so many different kinds of sensations?
What will be an ideal response?
Answer: A good answer will include the following key points.
• There are two ways in which information about the stimulus is coded: anatomical coding and functional coding.
• Johannes Müller proposed the doctrine of specific nerve energies, a type of anatomical coding, in 1826.
• According to this doctrine, different sensory modalities exist because signals received by the sense organs stimulate different nerve pathways leading to different areas of the brain.
• Functional codes rely on the fact that sensory receptors and neurons fire, or are inhibited from firing, only in the presence of specific sorts of stimuli.
• Information about which cells are firing, how many cells are firing, the rate at which cells are firing, and the patterning of each cell's firing forms a functional code.
