Most people think that our wisdom comes from the brain, but Swedish researchers have found that neurons that extend to our fingertips have the same way of doing things as neurons in the cerebral cortex. The basic common sense we have accepted for many years is that the entire nervous system of the human body is like a data collection network with various sensors, and sends various information back to the brain for unified processing. But if the latest research is true, it may overthrow this theory.
The paper was written by J Andrew Pruszynski and Roland SJohansson, and the journal Neuroscience published their abstracts online on August 31: "We believe that The peripheral neurons on the tactile processing path, like the peripheral neurons on the visual processing path, can perform feature extraction calculations normally performed by cerebral cortical neurons."
In other words: "Our tactile experience seems to have been treated by neurons on the skin before it is passed to the brain for further processing."
The study also describes the ability of skin neurons to pass Prusinsky's so-called "geometric data" of the touched object. He said: "Our research has found two first-order haptic neurons that not only provide information on the time and intensity of finger-sensitive skin touching objects, but also provide shape information about the objects being touched."
The sensitivity of this system depends on the distribution of the highly sensitive area of ​​a neuron on the skin.
The study is expected to change the current way of repairing nerve damage because the current theoretical hypothesis is that the cerebral cortex is responsible for all the work of the entire nervous system.
"If you want to restore the tactile function of nerve-damaged patients by regenerating the peripheral nerves, you can't just consider how many neurons are regenerated as you do now, but also precisely control the way these neurons are regenerated according to our findings, because this may be Can decide what information they will send to the brain," Prusinski said.
