Frontal lobes:: The executive brain

Objective. To describe the current basic functional neuroanatomy of the frontal lobes and complex cognitive processes associated with this wide brain zone. Development. We reviewed recent studies I with neurofunctional interest. We structured the frontal zones and the cognitive functions more specifically humans, named 'executive functions'. We classified the frontal syndrome into more specific syndromes; and, we reviewed the fronto-cortical and subcortical connections, which are the basis of the frontal zones and functions. Conclusions. The frontal lobe is not a single anatomical and functional brain region. Regions and fronto-cortical and subcortical circuits within the frontal lobe are associated with motor functions and cognitive processes highly specialized, which may be differently affected.
