How Flexible is the Brain's Circuitry?

How flexible is the brain circuit? The brain is a complex organ with about 100 billion neurons and about 1,000 to 10,000 synapses in each neuron (1). This organ is involved not only in controlling and adjusting the function of the body but also in perceiving and perceiving the world around the body. I believe that among humans it makes us a very adaptive and intelligent organism and gives us personality. But, as there are so many parts and connections, what will happen if the brain precision circuit is interrupted?

Scientists are currently challenging the theory of brain plasticity. People have always considered plasticity in early childhood, but after this important period of flexible growth the core circuit of the brain becomes hardwired. Otaru is considered to be part of a wired system. Therefore, when limbs are cut, the distribution area within the cortex should be silent forever. In the 1980 's, Michael Merzenich and his colleagues started research in this field. They did a series of experiments and produced strange results. In one such experiment, they cut adult monkey fingers. A few weeks later, they read the signals from the cortex of the monkeys. The expected result is that the hard-wired brain (in the area of ​​missing fingers) remains silent. They were surprised to find that neurons in that area were shot whenever a finger was touched.

Although the scientific community has reached an agreement on the possibility of a change in neural circuit of the brain through experience, the potential effect of network technology on the neural circuit of the brain is unknown. Regarding the influence of the Internet on reading skills, Guinevere F. Eden of Georgetown University Learning Research Center Director said that whether the Internet changed its brains in a good way for the Internet is a problem. It is unique. Carl believes that the Internet's impact on cognition is detrimental and detracts from concentration. Olds cites the potential benefits of computer software to learn disabilities and pointed out that some neuroscientists believe that neural plasticity based software is good for improving acceptable language barriers doing.

The brain was once believed to be a rather static organ, but it is now clear that the composition of the brain circuitry is constantly changing with changes in experience. These changes are called brain plasticity and are related to functional changes such as memory, poisoning, and functional recovery. Recent studies have shown that brain plasticity and behavior are affected by myriad factors including prenatal and postnatal experience, medication, hormones, maturation, aging, diet, illness, and stress. Understanding how these factors affect brain tissues and functions is important not only for understanding normal behaviors and abnormal behaviors but also for designing behavior and psychological disorders from poisoning to stroke Also important.
