Final answer:
The maturation of the prefrontal cortex improves various cognitive functions but is not directly responsible for two-handed coordination, which involves the motor areas of the brain and the cerebellum.
Step-by-step explanation:
The maturation of the prefrontal cortex is associated with several cognitive improvements, including better planning, impulse control, and decision-making abilities. However, it is not directly associated with two-handed coordination. The latter is more closely related to the motor areas of the brain such as the premotor cortex and supplemental motor area, which work alongside the cerebellum to plan and execute coordinated movements
. Both fine and gross motor skills, including those involving the use of both hands, do benefit from the improvements in cognitive function that occur as the prefrontal cortex matures, but the direct neurological pathways involved in two-handed coordination are distinct from those tied to the prefrontal cortex.
