Odour in Mice

Odour-induced analgesia mediated by hypothalamic orexin neurons in mice

Various folk remedies employ certain odorous compounds with analgesic effects. In fact, linalool, a monoterpene alcohol found in lavender extracts, has been found to attenuate pain responses via subcutaneous, intraperitoneal, intrathecal, and oral administration. However, the analgesic effects of odorous compounds mediated by olfaction have not been thoroughly examined. We performed behavioural...

Behavioural responses in mice exposed to predator odour components

Behavioural responses of mice to predator odour components

Sammanfattning/Abstract: Having means to detect and avoid potential predators is a necessity for prey species. Most mammalian prey species are able to detect odours emitted by predators and to adapt their behaviour accordingly. These odour cues are therefore considered to act as semiochemicals. Predator odours consist of several dozen different odourants. In order to assess if single odourants ...

Odour 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...

Is 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...
