Scientists have been able to find a scientific discovery that enables them to obtain accurate measurements of dopamine in the human brain whose deficiency leads to serious diseases such as depression, schizophrenia and Parkinson's disease.
MIT neuroscientists have devised a way to measure the level of dopamine in the brain over a year. They think it will help them to see its role more accurately in healthy, healthy brains, after it was impossible to see long-term changes in the past.
Dopamine is one of the neurotransmitters used by cells in the brain to communicate with one another. The conventional systems used to measure them were carbon nanotubes with a diameter of 100 microns, whose results could be trusted for approximately one day, creating a fabric that interferes with the ability of electrodes to interact with dopamine. In 2015, a team of researchers at the American Institute developed accurate sensors that could measure rates Dopamine in the brain area that contains the cells responsible for the production of the compound.
Because the probes are small "no more than 10 microns in diameter," researchers can cultivate up to 16 of them to measure dopamine rates in different parts of the planned area and try to use them in tracking the compound levels for a long time without any interference or induction of immune response. In their study, the researchers planted between 3 and 5 sensors in animal brains at a depth of 5 millimeters in the planned area, recorded readings over weeks after dopamine stimulation, and found their persistence for more than 393 days, giving them hope that the experiment could be applied to humans.
Monitoring Parkinson's Disease Scientists stress the importance of these sensors if successful in human composition in the control of Parkinson's patients, and the cultivation of an electrode that moves the pulse to the depth of the brain. Monitoring the sensors for dopamine rates will also help doctors more accurately guide the brain of patients when needed. Researchers are now adjusting the sensors to measure other neurotransmitters in the brain and measure electrical signals that may be impaired in Parkinson's patients, according to the institute's Web site.
