brain network efficiency

Brain network efficiency refers to how effectively different regions of the brain communicate and share information with each other. When the network is efficient, signals travel quickly and smoothly across regions, supporting quick thinking, problem-solving, and other cognitive functions. High efficiency means the brain can perform complex tasks with less effort, while low efficiency may be associated with slower processing or difficulty in integrating information. It’s similar to how a well-organized transportation system allows for faster travel; a more efficient brain network enables better coordination and cognitive performance.
