Alina knows that neurons are not arranged randomly in the human brain. In the cortex, they are organized into interconnected groups with high intrinsic connectivity.

This modular connectivity structure, in which groups of neurons unfold as functional units, is formed in the early stages of brain development.

This neural organization process, which establishes an order in the brain architecture, is regulated by the activity of the neurons, but until now it was unknown how the embryonic brain manages to establish active and balanced neural networks, from such early stages of its development. .

New research carried out at the University of Freiburg has discovered how this brain feat is achieved:...
