Scientists discover new mechanism of how brain networks form

Scientists have
discovered that networks of inhibitory neurons develop through a mechanism opposite to the one followed by excitatory networks. Excitatory neurons sculpt and refine maps of the external world throughout development and experience, while inhibitory neurons form maps that become broader with maturation. This discovery adds a new piece to the puzzle of how the brain organizes and processes information. Knowing how the normal brain works is an important step toward understanding the nature of neurological conditions and opens the possibility of finding treatments in the future.

“The brain represents the external world as specific maps of activity created by networks of neurons,” said Dr...
