It is not always well-defined for nonlinear, nonpassive sensory organs, since they can't function without input energy. For example, a cochlea is not a passive organ, but actively vibrates its own sensory hairs to improve its sensitivity. This manifests as otoacoustic emissions in healthy ears, and tinnitus in pathological ears. [26]
His favored example of this duality is Limburger cheese, which is known for its repulsiveness to the nose yet pleasantness to the mouth. Originally published in 2012, Neurogastronomy by Gordon M.
