Cognitive Control

Imagine your brain has a toolkit of LEGO bricks. These bricks represent small groups of brain cells that work together. To build a 'car' (one task), you combine a 'wheel' brick, an 'engine' brick, and a 'chassis' brick. To build an 'airplane' (a different task), you don't need a whole new set of parts. You can reuse the 'engine' brick, but combine it with a 'wing' brick and a 'fuselage' brick. This study found that the brain works similarly, reusing the same neural 'bricks' (called subspaces) in different combinations to handle various tasks, making it incredibly efficient and adaptable.
