Furthermore,
Scientists pass ray light through:
Our heads are opaque. Meanwhile, Light does not pass. For example, This is what we have always believed. Furthermore, What if it was wrong? Meanwhile, Scientists have just made an experience that seemed impossible: to pass a radius of light right through a human skull. Moreover, capture it on the other side. Nevertheless, It is a world first. Meanwhile, a technical feat that could ultimately change the situation for the diagnosis of diseases such as the cancer or Alzheimer.
What is this scientific feat? – Scientists pass ray light through
The feat was achieved by a team from theUniversity of Glasgowin Scotland. Similarly, The researchers managed to prove that it was possible to detect photons of light that crossed the entirety of. Therefore, a brain human. Moreover, This experience pushes the limits of an existing technology called fNIRS (near infrared spectroscopy). Until now, this technique has only been to probe scientists pass ray light through a few centimeters on the surface of the brain. Going deeper required a huge and expensive MRI machine. This discovery proves that there is another path.
How did the researchers realized this experience? – Scientists pass ray light through
To succeed where everyone had failed. the team used a laser more powerful infrared (while remaining without danger) and ultra-sensitive photons detectors. The experience, which lasted 30 minutes, took place in the full dark to avoid any interference. They directed the laser on one side of the head of a volunteer. placed the detector on the opposite side. Even if only a “net of photons” survived the crossing, it was enough. The researchers were able to prove, thanks to computer simulations, that the light had followed a path throughout scientists pass ray light through the brain.
What are the promises of this new imaging technique? – Scientists pass ray light through
You have to be clear: it is not yet a tool that can be used in the hospital. Experience only worked on a single volunteer with ideal characteristics (light skin, no hair). But it is proof of concept that changes everything. She could “Inspire the community to rethink what is possible”as researchers indicate. The long -term objective is to develop a new generation of devicesbrain imaging which would be portable. inexpensive, and capable of seeing in depth. A revolution to diagnose and follow strokes, tumors or head trauma, especially in places where access to MRI is limited.
No more questions
Is this technique ready for hospitals?
No not at all. It scientists pass ray light through is a fundamental research at a very early stage. The fact that it only operated on a single participant in very strict laboratory conditions shows that it remains a lot of work before considering a reliable. practical clinical application for all types of patients.
What is Fnirs?
It is the acronym for “Functional Near-Infrared Spectroscopy” (near functional infrared spectroscopy). It is a technique ofbrain imaging non -invasive which measures the activity of brain By analyzing the way in. which light is absorbed by the blood circulating there. It is a much cheaper and more portable technology than an MRI.
Has light crossed the brain at random?
No, and this is another interesting discovery. IT simulations have shown that light is not dispertained randomly. Additionally, It tends to follow “preferential paths”, including more “transparent” areas such as cerebrospinal fluid. Understanding these paths could better target future brain scans.
