'''Odotope Theory''', also known as Weak-Shape Theory, is a leading [[neurophysiology|neurophysiological]] theory of how the [[olfaction|sense of smell]] functions. The model is analogous to a molecular [[Braille]]: it is proposed that any number of the 347 different [[protein]]-based smell receptors in the nose binds to only certain parts of a smellable [[molecule]], and thus a few hundreds of different receptors can, through [[combinatorial explosion]], theoretically recognize an infinite number of distinct smells.

Odotope theory, also known as weak shape theory,[1] is a theory of how olfactory receptors bind to odor molecules. The theory proposes that a combination of shape factors determine the coupling. The word itself is an analogy to epitopes.
