Technology is finding solutions every day to improve health systems and recently researchers from the MIT carried out follow-up work on patients with Parkinson’s with the aim of improving their treatment.
This research was done taking as a reference their speed when moving around the house, a scenario that is usually far away during medical processes, which is why they are crucial data.
In the world there are about 10 million people with this disease, usually the motor skills and cognitive functions of these patients are evaluated through medical visits.
This situation can skew the information due to the exhaustion it represents, since some get tired just by traveling from home to the hospital or on the way to the doctor’s office.
For this reason, a team from MIT proposed a device that collects data using radio signals that are reflected by a patient’s body as they move around their home.
This device is similar to a router of Wi-Fi, so it is operating around the clock, adding an algorithm to detect the signals generated by other people in that room when they move.
The results showed that it is much more effective to collect data in this way to track the progression and severity of the disease, as was the case with the dozen people with Parkinson’s who participated in the study.
An example of what was achieved is that the speed of movement decreased almost twice as fast in all patients compared to those who were not. In addition, daily fluctuations in a patient’s walking speed correlated with how well they responded to the patient’s medication.
“By being able to monitor the patient and inform the doctor remotely about the progression of the disease and the patient’s response to medication. In addition, it allows the patient to be cared for, even if he cannot come to the consultation,” he said. Guo Zhangstudent of MIT and co-senior author of the study.
Where is language located in the brain?
Spanish, English, Italian, Ukrainian, and dozens of other languages activate the same language network in the brain every time speakers communicate. This was shown by a recent investigation by the Massachusetts Institute of Technology (MIT) noting that the location and key properties of the human language network appear to be universal.
For decades, neuroscientists have been mapping the language processing network in the brain, located primarily in the left hemisphere. However, the vast majority of those mapping studies have been done on people who spoke English while listening to or reading texts in the same language.
Now, MIT neuroscientists have analyzed brain images of speakers of 45 different languages. The study, published in Nature Neuroscience, showed that linguistic networks appear to be essentially the same in all people, regardless of the language they speak.
For example, in English, word order tends to be fixed, while in other languages there is more flexibility. Other languages use the addition of morphemes, or word segments, to convey additional meaning and relationships between words.
The team discovered that The participants’ language networks were located in roughly the same brain regions and had the same selectivity as native English speakers.
In addition, the researchers found that language regions that are normally activated together in English speakers, such as frontal language areas and temporal language areas, were similarly synchronized in speakers of other languages.
The researchers also showed that across all subjects, the small amount of variation they saw between people who speak different languages was the same as the amount of variation that would normally be seen between native English speakers.
