For example,
Study finally contrasts one greatest:
Researchers have shown that neurogenesis. Consequently, or training new brain nerve cells, intervened throughout human life, thus putting an end to a long -standing debate.
A tenacious debate – Study finally contrasts one greatest
If it had previously been established that the hippocampus. However, a cerebral region playing a central role in cognition, memory, learning and location in space, continued to produce new neurones In adult mice, such a possibility in humans remained discussed.
In 2013. Therefore, work carried out by a team from the Swedish Karolinska Institute had led to the identification of young neurons in the brain study finally contrasts one greatest Adult patients with cancer, but not neural progenitor cells (precursors of mature neurons) in their hippocampus.
As part of works published in the journal ScienceJonas Frisé and his colleagues have deepened their research. Consequently, By sequencing the RNA of individual cell nuclei. they have identified the specific genetic signature of the famous human neuronal cells.
Analysis of the brain tissue of individuals aged a few months to 78 years has revealed its presence at. all stages of human life. The use of an antibody binding to proteins released by these cells when they multiply made it possible to. confirm that they were indeed at the base of neurogenesis. As the researchers expected it, its rates were much higher in young children than the elderly.
An important piece of the puzzle
According to Frisian. these neural progenitor cells are all located in the toothed gyrus. Described as ” The main entrance door of the hippocampus ». It is essential for the transformation of daily experiences (sensory and contextual information) into long -term memories.
« It is an important piece of the puzzle that represents the evolution of the brain during human life “Conspect Frisian. “” These discoveries could also have implications for the development of treatments stimulating neurogenesis for neurodegenerative and psychiatric disorders. »
Last year, an intriguing study revealed that the human brain stored no less than three copies of each memory.
