Sentences with phrase «odour receptors»

To put the difference in context, we have 5 - 6 million odour receptors, while dogs have 220 million.

«There is a big trend towards odour receptors being found elsewhere in the body doing other jobs,» says Joel Mainland of the Monell Chemical Senses Center in Philadelphia.

The keys to the researchers» success were antibodies which recognise and bind to specific odour receptors or desensitisation proteins.

In Flavour, Holmes takes readers into a school that teaches food chemistry to chefs, a lab that studies odour receptors, and a factory specialising in artificial flavourings (which can range from «caricatures» of apple and melon to completely artificial tastes like bubblegum and Red Bull).

Not exact matches

Our CYBERNOSE ® biosensors mimic the sophisticated smell receptors of simple animals to detect and measure odours and chemicals in a range of substances.

Unlike the human receptors, which respond to odour molecules, the snakes» thermal receptors respond directly to heat, triggering nerve impulses that their brain interprets as an image.

It has been generally assumed that a smell arises when an odour molecule slides into a receptor like a...

The scientists used imaging techniques to visualize the activity in certain areas of the flies» brains while these were stimulated with different odours, and they were able to localize and identify the receptor for citrus.

They then used a computer program to simulate the part of the fly's brain used for recognition to show that the receptor responses contained enough information to recognise odours.

It is also possible that smell receptors on sperm respond to odour molecules that find their way into the circulation.

The receptors presumably then pass this information to the sperm's mitochondria, which power the cell towards the source of the odour.

They also searched for a second group of molecules called desensitisation proteins, which temporarily stop the receptor cells from responding to an odour.

The fact the sperm cell receptor molecules are found alongside desensitisation proteins — just as they are in the nose — strongly suggests that they detect odours, says Snyder.

There are about a thousand of these receptors detecting such things as light, flavour, odour, adrenaline and histamine.

Important advances have included the discovery of the first evidence that the odour response is governed by neurons, of the intracellular signalling pathways between odorant receptors and sensory neurons, and of specific neurons, receptors and neurotransmitters involved in behaviour adaption following experience.

We developed new methodologies and procedures that allowed us to investigate the specificity of odour recognition between odorant binding proteins and receptors in Anopheles gambiae mosquito.
