Their work is the subject of 17 articles published in the magazine Nature (New window) (in English).

It describes the 127 or so types of brain cells: their shapes, locations, patterns of electrical activity, and genetic characteristics.

The chief organ

The human brain contains over 160 billion cells.times more cells than there are people in this world “,” text “:” A brain has more than 20 times more cells than there are people in this world “}}”>A brain has more than 20 times more cells than there are people in this worldDr. Hongkui Zeng, director of the Allen Institute for Brain Science, said in a statement.

Knowing about all types of brain cells, how they are connected to each other and how they interact with each other, gives hope for the creation of therapies that we cannot even imagine today.adds Josh Gordon, director of the US National Institute of Mental Health (NIMH).

To understand how a system works, you first need to make a parts list. Then you have to understand what each part does and put the pieces together to see how the whole system works. This is what we did with the brain, continues the scientist.

For her part, Prof. Helen Bateup of the University of California at Berkeley compares this scientific effort to: “Here are all the cellular components, here are how many they are, here is where they are located and how they connect ” “,” text “:” the first page of the manual of how the brain works: “Here are all the cellular components , here is how many there are, here is where they are located and how they connect “”}} ‘>the first page of the manual of how the brain works: “Here are all the cellular components, here is how many there are, here is where they are located and how they connect”.

Brain under the magnifying glass

While it is true that all humans generally share the same brain structure, genetic and environmental factors also influence its development and function.

Thus, each person’s brain reflects their unique journey and life experiences. Better understanding its structure and function will help researchers better understand the types of cells associated with the diseases that develop there, and identify the corresponding cells in the animal model. Ultimately, this work will make it possible to better explain how diseases such as Alzheimer’s and schizophrenia develop, and to target treatments according to cells.

To do this, neuroscientists must first understand how all cell types behave and interact with each other in a healthy brain.

We will now try to understand how they [les cellules] work together. The task is immense. Thanks to the new census, we know to what extent we do not know! And this is progresssays neuroscientist Kenneth Harris of University College London.
