Question

Quizplus · Accepted Answer

The doctrine of specific nerve energies suggests that nerves carry specific messages that are interpreted by the brain as specific sensations. So, electrical stimulation of a sensory nerve can evoke a specific sensation.

Answer: C
 This statement is not consistent with the doctrine of specific nerve energies. The doctrine states that nerves carry specific messages that are interpreted as specific sensations. However, exerting pressure on the eyeball evoking the sensation of sound is not consistent with this idea.

Answer: D
 This statement is consistent with the doctrine of specific nerve energies. Even though psychological stimuli does not directly activate nerves, it can activate sensory receptors that then send specific messages to the brain, which are then interpreted as specific sensations.

 This statement is not consistent with the doctrine of specific nerve energies. Specific nerve energies state that nerves carry specific messages that are interpreted as specific sensations, meaning that the height of the action potential should not depend on which sensory system has been activated as all nerve impulses carry the same type of informational content.
