Odour 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 کاملHoneybees Learn Odour Mixtures via a Selection of Key Odorants
BACKGROUND The honeybee has to detect, process and learn numerous complex odours from her natural environment on a daily basis. Most of these odours are floral scents, which are mixtures of dozens of different odorants. To date, it is still unclear how the bee brain unravels the complex information contained in scent mixtures. METHODOLOGY/PRINCIPAL FINDINGS This study investigates learning of...
متن کاملOdour Regulation in Germany – an improved system including odour intensity, hedonic tone and odour annoyance
For odour regulation in Germany the Guideline on Odour in ambient Air GOAA has been in use for many years. The main parameter the odour regulation authority has to take into account is the odour frequency expressed as odour hours per year. In the Guideline limit values are given for the maximum odour frequency per year. These limit values are based on investigations in the field in which signif...
متن کاملConversion of the chemical concentration of odorous mixtures into odour concentration and odour intensity: a comparison of methods
Research Highlights Concentration of odorous substances as surrogate for odour concentration/intensity Comparison of conversion methods with various degrees of complexity Model evaluation by seven VOCs: 23 binary mixtures and 5 mixtures of 7 substances Model input: odour threshold concentration and the slope of the Weber-Fechner law No further calibration by olfactometric measurements...
متن کاملIs short-term odour recognition predictable from odour profile?
Smelling an odour induces a pattern of sensations, images and memories which participate in identification. It was proposed that perceptual memory performances for odours could be inferred from the description of these olfactory representations. The subject was asked to elaborate an odour descriptor profile, and a short-term odour recognition memory task was chosen to test the individual percep...
