The code of neurons of the brain stem nuclei of the taste pathway seems remarkably similar to that of the first-order afferent fibers. The thalamic and cortical representation of taste is as yet terra incognita, but is currently being surveyed.

Two theories of the representation of odor quality are discussed: one is based on topographic representation of smells, the other on a frequency-code.
