The frontal lobe is the largest of the four major lobes of the brain in mammals, and is located at the front of each hemisphere (in front of the parietal lobe and the temporal lobe). Neuroscientists have traditionally divided the brain's cerebrum into four lobes: the frontal, parietal, occipital, and temporal. Traditionally, each of the hemispheres has been divided into four lobes: frontal, parietal, temporal and occipital. The authors have declared that no competing interests exist. The outermost and largest part of the brain, called the cerebrum, is divided into halves called hemispheres.
