Jacobson s Organ must be a precision olfactory organ which can be excited by a minima amount of odourants".

Three hundred years ago anatomists observed that humans had two tiny dents on either side of the nose cavity and about a centimetre up from the nostrils. This is the vomero-nasal organ (VNO), also known as Jacobson s organ, named after the man who published a detailed description of animal VNOs in 1811. The human VNO has generally been ignored because it was clearly of no importance since there are no nerve connections between it and the brain. It appears to be merely the vestige of some early evolutionary organ. The VNO is very impor-...

Pheromone-induced responses are mediated primarily by the vomeronasal organ (VNO). The VNO, also known as "Jacobson s organ" [244] since 1944, is part of an accessory olfactory system. It is present in a variety of non-human vertebrates but its existence in the human has been open to question until recently. The VNO was first discovered by Ruysch (1703), a military doctor, in a soldier with a facial wound. The organ was named after Jacobson who published his findings on animals, but not humans, in 1811.

Although we know the tongue and Jacobson s organ constitute the primary mechanism for the input of information from trails (Halpern and Kubie, 1983), we have little insight into how snakes utilize odors to orient spatially to locate either food or mates. To obtain some basic information on trail orientation, I filmed ten males of four species of snakes following female trails laid in the arena described previously (Fig. 2).

Strong olfactory stimuli often release the peculiar self-anointing behavior of hedgehogs and tenrecs, which was interpreted as a means of cleaning the oral cavity and the Jacobson s organ of the olfactory stimulant (Poduschka and Firbas, 1968 Poduschka, 1977a but c.f., Brodie,...
