Yale researcher discovers "brain temperature tunnel"

16.07.2003


Yale researcher M. Marc Abreu, M.D., has identified an area of the brain he calls the brain temperature tunnel, which transmits brain temperature to an area of skin and has the potential to prevent death from heat stroke and hypothermia, and detect infectious diseases such as Severe Acute Respiratory Syndrome (SARS).

Abreu, a postdoctoral fellow in the Department of Ophthalmology at Yale School of Medicine, found that a small area of skin near the eyes and the nose is the point of entry for the brain temperature tunnel. His research shows that this area is connected to a thermal storage center in the brain, and the area has the thinnest skin and the highest amount of light energy. He has constructed patches and eyeglasses designed to continuously measure brain temperature at this entry point.

Unlike other vital signs like heart rate, blood pressure and respiratory rate, which can be monitored continuously, core body temperature measurement cannot be currently measured continuously and non-invasively.



"With the discovery of the brain temperature tunnel, sunglasses and eyeglasses will serve not only visual function, but also functions that sustain and enhance human life and performance," said Abreu.

Abreu said this discovery could impact a host of health issues such as athletic performance and training, enhancing safety and performance of athletes, firefighters, members of the military and outdoor recreationists. Abreu said the discovery could also help protect the world food supply and improve food safety by continuous monitoring of infectious diseases in animals such as foot-and-mouth disease, bovine tuberculosis, anthrax and mad cow disease.

For those who are sick at home and in hospitals, Abreu said this discovery could also provide continuous temperature monitoring without the need for nurse intervention. "One of the most important causes of death is hospital infection, which kills more than 100,000 patients a year in the United States," said Abreu. "The inability to detect temperature changes in a timely fashion can lead to spread of infection and even cause death. Monitoring the brain temperature tunnel can detect infection early, so timely therapy can be administered and complications prevented."

Abreu said, "The brain temperature tunnel has enabled the creation of systems that enhance performance while maximizing safety in hot or cold temperatures and preventing dehydration or overhydration."

Abreu explains that when athletes, military personnel, construction workers and firefighters die from heat stroke, it is because the brain temperature rises rapidly to dangerous levels and lack of timely detection and intervention causes brain damage. He further explains that physical performance is decreased because the blood is used for cooling the body. The high temperature in the brain can also lead to thermal induced injury and impaired cognitive function.

"Monitoring brain temperature will also enable women to use a natural method for tracking fertility and birth control," said Abreu. "Automated detection of ovulation can also enhance programs for artificial insemination in animals on dairy farms and in zoos."

Im Focus: Can we see monkeys from space? Emerging technologies to map biodiversity

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.

Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...

Im Focus: Climate satellite: Tracking methane with robust laser technology

Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.

Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...

Im Focus: How protons move through a fuel cell

Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.

As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...

Im Focus: A unique data centre for cosmological simulations

Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.

With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...
