- Select a new search method that hinders the ability of the old biological clock of mammals to re-adjust when exposed to light, which deactivates sleep patterns and consequent threats to well-being.
- The researchers found, led by the specialist in the physics of nerves at the University of Kent, that aging leads to a significant decrease in sensitivity to light in the part of the brain that controls the daily rhythms, known as the suprachiasmatic nucleus. (SCN)
- This can help in the selection of penetration treatments aimed at improving the “time to redefine” the physiological and behavioral clock in the elderly.
- Explore Dr. Gribert Lal, of the Medway School of Pharmacy, and other members of the research team, the changes in one of the clues of the part of the brain that controls the daily rhythms. The researchers found that the future of glutamate (NMDA), which is used for the transfer of optical information, has become less effective in re-adjusting daily time as part of the aging process.
- This structural change in the glutamate receptors was responsible for the decrease in the response to light observed. The NMDA subunit showed a significant decrease in presence among older mammals, indicating a change related to age in structural composition.
- The study concluded that the aging of SCN suffers from a structural reorganization of the light-receiving components. Eventually weakening its function to identify and maintain the daily rhythm.
