Tuning in Other Systems
Neurons in other systems also become selectively tuned to stimuli. In the auditory system, different neurons may respond selectively to the frequency (pitch), amplitude (loudness), and/or complexity (uniqueness) of sounds. In the olfactory system, neurons may be tuned to certain kinds of smells. In the gustatory system, different neurons may respond selectively to different components of food: sweet, sour, salty, and bitter. In the somatosensory system, neurons may be selectively tuned to different types of pressure, temperature, bodily position, and pain. This tuning in the somatosensory system also provides feedback to the motor system so that it may selectively tune neurons to respond in specific ways to given stimuli. Finally, the encoding and storage of information in both short-term and long-term memory requires the tuning of neurons in complex ways such that information may be later retrieved.

Famous quotes containing the word systems:
“I am beginning to suspect all elaborate and special systems of education. They seem to me to be built up on the supposition that every child is a kind of idiot who must be taught to think.”
—Anne Sullivan (1866–1936)
