Odour perception: an object-recognition approach.
Object recognition is a crucial component of both visual and auditory perception. It is also critical for olfaction. Most odours are composed of 10s or 100s of volatile components, yet they are perceived as unitary perceptual events against a continually shifting olfactory background (i.e. figure-ground segregation). We argue here that this occurs by rapid central adaptation to background odour...
متن کاملOdour perception in honeybees: coding information in glomerular patterns.
Major advances have been made during the past two years in understanding how honeybees process olfactory input at the level of their first brain structure dealing with odours, the antennal lobe (the insect analogue of the mammalian olfactory bulb). It is now possible to map physiological responses to morphologically identified olfactory glomeruli, allowing for the creation of a functional atlas...
متن کاملChronic Renal Disease: Orthomolecular Ramifications
Introduction Increasingly, human kidneys are under assault from environmental toxins as well as an array of diseases that place them at risk of ultimately failing. Eleven percent of American adults now show evidence of chronic kidney disease, with over 400,000 afflicted with end-stage kidney disease. Over a third of those cases are caused by diabetes, and the remainder by high blood pressure an...
متن کاملIron absorption in chronic renal disease.
1. Absorption of inorganic iron was studied in thirty-four patients with chronic renal failure by a double isotope technique. 2. Eight patients with normal iron balance had a mean absorption of 3-5%, ten patients with iron overload had a mean absorption of 3.6%, and sixteen patients with iron depletion had a mean absorption of 58%. Thus, alterations in absorption appeared to be related to distu...
متن کاملPleasant and unpleasant odour-face combinations influence face and odour perception: An event-related potential study
Odours alter evaluations of concurrent visual stimuli. However, neural mechanisms underlying the effects of congruent and incongruent odours on facial expression perception are not clear. Moreover, the influence of emotional faces on odour perception is not established. We investigated the effects of one pleasant and one unpleasant odour paired with happy and disgusted faces, on subjective rati...
