Does the brain also have fingerprints?

In the 17th century, Italian biologist Marcello Malpighi observed that there are unique ridges and sweat glands on each person's fingertips
.

Since then, fingerprints have become a technology used to identify individuals
.

Until now, this technology is still widely used, and the concept of fingerprint recognition has been extended to other biometric fields, such as voice recording and retinal scanning
.

Just a few years ago, neuroscientists at Yale University discovered that everyone’s brain has its own unique brain "fingerprint
.
"
They found that by comparing the subjects’ MRI scans several days apart, they were able to identify the two scans of a given subject with nearly 95% accuracy
.

In other words, they can accurately identify a person based on brain fingerprints
.

However, unlike fingerprints, brain fingerprints will change over time, and the time scale of this recognizability remains largely unexplored
.

In a new study published in Science Advances, researchers found that it only takes 100 seconds to identify the unique fingerprint of the brain
.

Now, the extraction of "fingerprints" from the data of the human brain connection group has become a new frontier in neuroscience
.

Enrico Amico is a computational neuroscientist at the Federal Institute of Technology in Lausanne (EPFL).
After learning about the findings of Yale University researchers, he was shocked and decided to take this discovery one step further
.

In previous studies, neuroscientists have achieved brain fingerprints through two MRI scans performed over a long period of time
.

But Amico wants to know, is it possible that these fingerprints will actually appear after five seconds? Or maybe the fingerprints of different brain regions appear at different points in time? No one knows the answers to these questions
.

So, the Amico team decided to test different time scales to see what happens
.

In the new study, they examined the networks and connections inside the brain, especially the connections between different regions
.

They mainly use MRI scans to measure brain activity during a specific period of time, and then process the scan results to generate charts in the form of color matrices that summarize the brain activity of the subjects
.

All the information scientists need is hidden in these diagrams, which are often referred to as "functional brain connectivity groups
.
"

.

Connection groups are the mapping of neural networks.
In essence, they are just a series of related values
.

From these connected groups, scientists can know what the subjects are doing during the MRI scan, such as whether they are resting or performing other tasks
.

In the new study, the connection group data will change based on the activity being performed and which part of the brain is being used
.

Amico said: "We realized that the information needed to develop a brain fingerprint can be obtained in a very short time
.

"The results of the study show that although a few seconds are not long enough to detect useful data, about 1 minute and 40 seconds are enough to obtain these brain fingerprints
.

In addition, they also found that different parts of the connected group fingerprints have different time scales.

The
fastest brain fingerprints begin to appear in the sensory areas of the brain, especially those related to eye movement, visual perception, and visual attention
.

Over time, the areas of the frontal cortex related to more complex cognitive functions Also began to show unique information
.

Next, researchers will compare the brain fingerprints of healthy people and patients with Alzheimer’s disease
.

According to preliminary analysis, researchers have found that the unique characteristics of brain fingerprints seem to change with the disease.
As people develop and disappear steadily, it will become more and more difficult to identify people based on their connected groups
.

This seems to mean that people with Alzheimer’s have lost their brain fingerprints
.
It
can be said that this study It helps us to make another small step towards understanding the uniqueness of the human brain, and researchers believe that this advancement promises to create unlimited opportunities
.
The
researchers say that potential applications of this discovery may include the loss of brain fingerprints.
Early detection of diseases may help treat patients with autism, stroke, and even drug addiction
