Frontal lobe
Part of the brain
The frontal lobe is the largest lobe of the vertebrate brain and the most anterior lobe of the cerebral hemispheres. The anatomical groove known as the central sulcus separates the frontal lobe from the parietal lobe, and the deeper anatomical groove called the lateral sulcus separates the frontal lobe from the temporal lobe. The most anterior ventral, orbital end of the frontal lobe is known as the frontal pole, which is one of the three so-called poles of the cerebrum.
