In sensory processing, what is meant by "temporal summation"?
- The summation of multiple stimuli presented at different locations simultaneously.
- The integration of sensory signals received at different times. (correct)
- The decrease in response strength over time with a constant stimulus.

What is the primary function of hair cells in the auditory system?
What is the primary function of hair cells in the auditory system?
- To detect changes in air pressure and convert them into electrical signals. (correct)
- To protect the inner ear from physical damage.
- To regulate the balance of fluids within the ear.
- To produce earwax for trapping foreign particles.
Hair cells in the auditory system are specialized sensory cells that detect mechanical changes in air pressure (sound waves) and convert them into electrical signals for auditory processing.
How do sensory systems encode the intensity of a stimulus?
Hair cells in the auditory system are specialized sensory cells that detect mechanical changes in air pressure (sound waves) and convert them into electrical signals for auditory processing. How do sensory systems encode the intensity of a stimulus?
- By changing the type of neurotransmitter released.
- By altering the amplitude of action potentials.
- Through the frequency of action potentials. (correct)
- By switching between excitatory and inhibitory responses.
