The brain comprises billions of interconnected neurons that transmit and process information and allow it to act as a highly sophisticated information processing system. To make it as efficient as possible, the brain develops multiple modules tasked with different functions, like perception and body control. Within a single area, neurons form multiple clusters and function as modules—an important trait that has remained essentially unchanged throughout evolution.The brain comprises billions of interconnected neurons that transmit and process information and allow it to act as a highly sophisticated information processing system.
