The scientists likewise see distinctions between brain areas. The frontal lobe, the front part of our brain accountable for believing and performing tasks, develops longer than a location accountable for motion.
Brain map
The scientists got the data by making precise measurements utilizing an electrode grid that some epilepsy clients get positioned on their brains (under the skull) in preparation for epilepsy surgery. “By stimulating the electrodes using short currents, we can see which brain locations react abnormally.
The fact that the data might likewise teach the scientists something about how our brain works was a new insight. “We have been gathering this data for about twenty years,” Leijten stated. “It wasnt up until a couple of years ago that we recognized we could use the untouched areas as a design for the healthy human brain.”
Van Blooijs includes: “If you stimulate an electrode in one area, a reaction happens in another. That lets you know the two areas are connected. You can then measure for how long it takes for the reaction to occur. If you know the range between the 2 different brain areas, you can compute how fast the signal is sent.”
Much better computer models
The outcomes of this study supply crucial information about our central nerve system. Scientists have actually long been attempting to map the connections in our brains. With this details, experts can make more realistic computer system models of our brains.
For these models to work, in addition to info about the connections, precise values concerning the speed of those connections are required. “We now have these numbers for the extremely very first time,” Leijten explains, “With our data, researchers can make new and better computer system designs that increase our understanding of the brain. We expect our work to not only advance epilepsy research but also research study into other brain conditions.”
Open to progress
With this publication in Nature Neuroscience, all data has actually become publicly available. This is called Open Science and it suggests that scientists from all over the world can utilize the information. Leijten: “By taking part in research, patients contribute to progress. The understanding we get can be utilized to much better reward future patients.” Van Blooijs will receive her doctorate at the end of this year. She says, “A lot is possible with this data, more than we can do. Im curious to see what type of research study all the imaginative individuals around the world will create.”

The researchers found, amongst other things, that the connections in our brains become increasingly quicker: from 2 meters per second in children aged 4 to four meters per second in people aged in between thirty and forty. “Our brain continues to establish a lot longer than we thought,” Van Blooijs said.
Current research study from UMC Utrecht and the Mayo Clinic exposes that our brain decreases behind formerly believed, happening between ages 30 and 40 rather of after 25. By studying electrode grids put on epilepsy patients brains, researchers discovered that brain connections end up being faster with age, doubling in speed, and supplying brand-new insight into brain function and development.
” Our brain continues to develop longer than we thought,” mentions Ph.D. trainee Dorien van Blooijs.
According to current findings from the University Medical Center Utrecht (UMC Utrecht), our brains decline occurs later than formerly believed. The study, published in Nature Neuroscience, exposes that the decrease takes place between the ages of 30 and 40, rather of after our 25th birthday.
Dorien van Blooijs, a medical technologist, and Frans Leijten, a neurologist, worked together with coworkers from both UMC Utrecht and the Mayo Clinic to carry out a study on the aging process of our brains processing speed.
Faster connections
The researchers discovered, amongst other things, that the connections in our brains end up being progressively much faster: from two meters per second in kids aged four to 4 meters per second in people aged in between thirty and forty. A doubling, simply put. Only after that age does it slow down. “Our brain continues to develop a lot longer than we thought,” Van Blooijs said.
The researchers obtained the data by making precise measurements using an electrode grid that some epilepsy patients get positioned on their brains (under the skull) in preparation for epilepsy surgical treatment. The fact that the information could also teach the scientists something about how our brain works was a brand-new insight. “We now have these numbers for the extremely first time,” Leijten discusses, “With our data, scientists can make new and better computer designs that increase our understanding of the brain.
