This article explores the development and neural positioning of executive functions in the brain from a cognitive neuropsychology perspective. The study aims to better understand how the brain structures responsible for executive functions evolve, starting in early childhood and continuing into adulthood. Research has shown that the prefrontal cortex matures gradually, with some areas still developing during adolescence and adulthood. This gradual development is linked to our ability to perform complex cognitive tasks. Executive functions like working memory and cognitive flexibility develop in parallel with the growth of the prefrontal cortex, which has been active since childhood. In addition,  several brain regions contribute to these functions. The prefrontal cortex is considered the main hub, receiving signals from various other parts of the brain. Recognizing how executive functions evolve is crucial for understanding how we use them in problem-solving and task performance. This understanding also plays a key role in creating better educational and cognitive programs aimed at supporting the rehabilitation of these brain functions.
