Unable to process the form. Frontal Lobe The frontal lobe is located in the anterior part of the cerebral hemispheres: • Anterior to the parietal lobe. It is divided into four gyri, which in reality are more 'regions' than true gyri, in that each is convoluted and divided by smaller incomplete sulci, which in turn are separated from each other by three main sulci 4.Â, Although each gyrus and sulcus are discussed individually, a brief overview is presented here.Â, The medial surface of the frontal lobe, abutting the falx in the midline, is primarily divided by the curving cingulate sulcus, which parallels the outer outline of the corpus callosum.Â. The hindbrain controls respiration and heart rate. 7. Cortex. Posteroinferiorly it is separated from the temporal lobe by the lateral sulcus (Sylvian fissure), although not seen from the surface is the insular cortex which is hidden deep to the lateral sulcus 2,4. It is divided into two parts, by two sulci. 9. Le lobe frontal est une partie de l’encéphale située à l’avant du cerveau. Position. 2.
