In the recent development, researchers have now developed a light-based technique which is for measuring the very weak magnetic fields like the things that are produced when the neurons are got fired into the brain. This inexpensive, as well as compact sensors, would be offering an alternative to the magnetic resonance imaging(MRI) systems which are currently used to map the brain activity.
As per the research member, BabakAmirsolaimani who is from University of Arizona, Tuscon has said that this portable, as well as low-cost brain imaging system, can get operate at room temperature in unshielded environments which will allow the real-time brain activity that uses to do mapping of potential concussions on the sports field and also in a conflict zones where the effect of the explosives on the brain can be proved as catastrophic.
The reports that were detailed in Optics Letters shows that the researchers have fabricated about the magnetic sensors which will be used for the optical fibers as well as they developed a polymer-nanoparticle composite which is sensitive to the magnetic fields. This sensor can able to detect the brain magnetic field which is about the 100 million times weaker than the magnetic field that is present on the earth surface.
The researchers can able to shows about the new sensors which can able to detect the weak magnetic pattern of the human heartbeat, and it can detect the magnetic fluctuations which can change every microsecond from an area which ranges from small as 100 square microns.
This new sensor will be helping the scientists to have a better understanding of the activity of the brain as well as the disease of the brain that it suffers from dementia and Alzheimer’s. They are also useful for measuring the magnetic fields to predict volcanic eruptions.
