Olfactory Responses to Milk Powder on Foodstuff Pests

Olfactory-like Responses in Pyriform Area to Non-Olfactory Stimulation *

Considerable doubt continues to exist about the r6le of finely myelinated and unmyelinatedt visceral afferents in the function of the cerebral cortex. Recent evoked potential studies involving stimulation of the chorda tympani, "" the vagus, 7l and the splanchnic nerves' have failed to establish that impulses transmitted along the slow-conductingt components of these nerves reach the cortex. It...

Olfactory Responses of Blowflies to Aliphatic Aldehydes

The response of the blowfly Phormia regina to stimulation by aldehydes in the vapor phase has been studied by means of a specially designed olfactometer. The median rejection threshold and the maximum acceptance threshold were selected as criteria of response. For both acceptance and rejection the distribution of thresholds in the population is normal with respect to the logarithm of concentrat...

Human olfactory receptor responses to odorants

Although the human olfactory system is capable of discriminating a vast number of odors, we do not currently understand what chemical features are encoded by olfactory receptors. In large part this is due to a paucity of data in a search space covering the interactions of hundreds of receptors with billions of odorous molecules. Of the approximately 400 intact human odorant receptors, only 10% ...
