Research has linked hunger and increased smell perception in the brain.
February 10/Bordeaux, France/Nature World News -- Research funded by the European Research Council has succeeded in linking hunger and increased smell perception in the brain, a link that reveals more about the biological factors that urge a person to eat.
The researchers have discovered how this mechanism is initiated in the endocannabinoid system in mice. The system allows communication between receptors in the brain and those involved in sensations such as euphoria, anxiety or even pain, that are also sensitive to cannabinoid substances, such as cannabis.
