Neurons, UNIGE scientists studied different populations during development.
Neurons, which are essential for communication between parts of the brain, share similar genetic programs, but at different rates.
The cerebral cortex, located above the brain, controls the brain, language, and complex functions that allow it to show the world or point to the future. The cortex, which can divide and group the stimuli we receive from our five senses, makes this information meaningful by combining this information.
It involves the development of the fetus and the formation of cortical connections through various neurons in the early postnatal period. What is the biological mechanism by which this delicate mechanism is made? A team from the University of Geneva (UNIGE) in Switzerland has recently pointed out this process:
Although neurons are physically different, their genetic programs are very similar.
Differences occur during the molecular maturation of neurons, which must follow a correct rhythm in order to establish a proper relationship. You can see these amazing results in Nature Magazine.
The various functions controlled by the cortex of the large brain are not randomly distribute, but are arrange according to an accurate map. For example, visual fields are located at the back of the head, with the grip of the hand on the side and motor control on the front. However, effective coordination is need to accomplish the various tasks in these areas.
These links are essential for building a unified worldview. However, it is important to choose combinations so that combinations are not incorrect and the most useful combination is chosen.
The general genetic score was play at another time.
Communication between cortical fields is mediate by “airborne cortical projection neurons” (ICPNs), which send electrical signals to cortical signals. Denis Jabaudon said: “In order to communicate with the cortical regions, the system must be fully connected and a variety of contacts must be made where and when necessary.
To understand how this happened, Dr. Dennis Jaboudin, a researcher on the team. Esther Klingler and her colleagues studied the relationship between birth control and motor skills in mice after birth.
“Surprisingly, the genetic programs of the two ICPN populations were not at all different, despite their physical differences.
Thus, the neurons that make certain types of connections grow faster, connecting to other cortical areas that grow more slowly. “Our work shows that diversity in neurons does not always require much genetic modification. In this case, it is like honey, only the rhythm of the music changes.”
Scientists have modified the implementation of this genetic program to confirm their findings. Usually by showing too many genes that reveal themselves at the beginning of the process. The rats then showed exceptional sensorimotor connectivity and an unusual environment. This change has turned the whole system upside down.
Sensitive action relationships come first.
Therefore, the degree of maturity of different types of nerves varies. Which appears in the period when there is a connection between areas of the brain. “In mice, the active search for the environment gradually takes place in the first two weeks of life according to the sequence of connections between the respective brains,” said Dennis Jaboudin.
“The continuous development of these different neurons allows the sensory abilities to emerge in such a time: newborn mice must first suck, and then strategically relate – and then the motor skills developed elsewhere. The brain needs to move forward to develop. “The Step Cortex learns to make connections only when data needs to be process correctly. Even our brains have time and space for everything.
