Tonotopic maps in the auditory core regions have shown that
A)the characteristic frequencies of the neurons gradually shift from lower at one end to higher at the other end.
B)the characteristic frequencies of the neurons appear to be randomly determined.
C)the arrangement of neurons is related to temporal coding but not to place coding along the basilar membrane.

Question

Quizplus · Accepted Answer

Tonotopic maps are organized according to the frequency selectivity of specific groups of neurons in the auditory core regions of the brain. These maps show that the arrangement of neurons is orderly, with the characteristic frequencies of the neurons gradually shifting from lower at one end to higher at the other end. This suggests that the auditory system uses place coding, where different frequencies of sound are represented at different locations along the basilar membrane in the cochlea, and this is reflected in the tonotopic maps in the brain.
