Use of Advanced Imaging to Assess Magnetite Levels
The human body has many inbound secrets, which is still unknown to physicians. Technological innovations are the only key to unlock that hidden mechanism in the human body. In 1992, researchers identified the presence of magnetite in the human brain. The magnetite is an iron oxide that has a permanent place inside the human brain. It is no surprise for the researchers because the presence of iron in the human body is common as other organisms. Magnetite is mostly present in ferritin (an intracellular protein). Recently, many types of research have been undertaken to diagnosing magnetite.
Presence of magnetite can sometimes become a threat to the human being. As the brain reacts to the external magnetic fields, the presence of magnetite is incidental. The level of magnetite exceeds for the patients who have Alzheimer’s disease.
Investigators at the Martinos Centre for Biomedicinal Imaging used the magnetoencephalography technique to measure the levels of magnetite levels in the brain. Moreover, the method also detects the weak signals coming from the normal current signals from the brain. David Cohen, Ph.D., of the Martinos Center, says that diagnosing the levels of magnetite using medical devices may allow new roles in a normal brain.
Before the advent of the magnetoencephalography, researchers said that the presence of magnetite was only observed in postmortem brains. According to the study by Cohen’s investigation of MEG signals, the team has come up with a better understanding of alternating current fields. Earliest MEG studies had found that, when a single healthy hair follicle is pressed over the scalp, there would be a single ray of the magnetic field produced. But, recent researches have found that not a single but plenty of magnetic rays are released from the brain. As a result, the research helps the investigators to measure the levels of the magnetic material within the head. Through the research, the location of the magnetite in the brain is also identified. It helps to regenerate the weak signals coming from the brain.
