1. Young drivers' brains are still maturing, with the prefrontal cortex responsible for cognitive control developing into early 20s. This can impact risky decision-making. 2. Studies using fMRI show alcohol impairs working memory and motor skills. Developing brains are also more sensitive to rewards and emotions. 3. Neuroscience research indicates certain activities like music and academics help strengthen brain connections during development, while passive activities do not provide the same benefits. Mature decision-making involves balancing emotions and cognitive control.
