Tonotopic organization
From Pickles (1988)
| One feature that is
common to all parts of the auditory system is tontopic organization. If you
measure the best frequency of neurons in say, the cochlear nucleus as shown
here, as you advance your electrode to the next neuron there is a progressive
decrease in best frequency. This graph shows that there are really two
Òfrequency mapsÓ in the cochlear nucleus. At least one part of each nucleus
in the auditory pathway is tonotopically organized. |
