Today, cognitive scientists try to link facial expressions to emotions in order to track the genetic and chemical pathways that govern emotion in the brain.
Dr. Sprinson elucidated the chemical pathways by which sugars are converted to the amino acids, their regulation, and interconversion of steroids.
The chemical pathways differ from the biological ones in that they all demand manmade energy, either via electricity or the direct burning of fossil and other fuels.
The drugs activate at least one of the chemical pathways triggered by resveratrol, a substance that also showed increased endurance in mice.
The hypothalamus and pituitary gland are connected by both nervous and chemical pathways.
Two chemical pathways are employed, and both are essential for the normal life of the red cell.
The signals converge on the brain mechanisms for the feeding motivation over nervous and, possibly, humoural (chemical) pathways.
Instead of endlessly rejiggering diets and exercise regimens, a new wave of scientists is getting at the molecular causes of appetite and satiety, unraveling elaborate chemical pathways that control how much animals, including people, eat.
A25 ARTS E1-10 SCIENCE TIMES F1-12 Behind the Desire to Eat A new wave of scientists is getting at the molecular causes of appetite and satiety, unraveling elaborate chemical pathways that control how much animals, including people, eat.
It, too, relies on catalysis, though in this case the best-tested chemical pathways generate amino acids and proteins, rather than RNA.
The chemical pathways utilized are more complex than those of the red cells and are similar to those of other tissue cells.
