Functional MRI evidence for disparate developmental processes underlying intelligence in boys and girls.

abstract：:In our daily life, we constantly exert sustained and phasic cognitive control processes to manage multiple competing task sets and rapidly switch between them. Increasing research efforts are attempting to unveil how the brain mediates these processes, highlighting the importance of the prefrontal cortex. An intriguin...
