Figurę 2.35 Auditory Pathways

The cochlea transduces sound into eleclrn al signals. Axons convey Ihese signals to the dorsal and ventra! cochlear nuclei, where it is tonotopically organized. Following a series of integrated relay pathways, the ascending pathway projects to the thalamus (medial genie ulate bodies) and then the acoustic cortex in the transveise gynis ot the temporal lobe, where intormation is tonotopically represented (Iow, middle, and high tones).
