Summary
Human brain lateral view - Lobes
- Lobus frontalis
- Lobus parietalis
- Lobus temporalis
- Lobus occipitalis
- Sulcus lateralis
- Sulcus centralis
- Sulcus parietooccipitalis
- Incisura preoccipitalis
- Polus frontalis
- Polus occipitalis
- Polus temporalis
The most rostral part of the Forebrain is the Cerebrum or Telencephalon made up of two Cerebral Hemispheres. The Cerebrum has an outer, highly stratified layer of gray matter called the Cerebral Cortex which is thrown into a series of folds or Gyri (singular = gyrus) which greatly increase the surface area of the cortex. The grooves between the gyri are called Sulci (singular = sulcus). Deep grooves are often referred to as Fissures. Deep to the cortex is the white matter along with several large nuclei located internally called Basal Ganglia.
Note the Frontal, Temporal, and Occipital Poles. The Poles are reference points indicating the furthest extent of the Frontal & Temporal Lobes anteriorly, and the Occipital Lobe posteriorly.
The Cerebrum is divided into 5 Lobes. On the lateral surface the Frontal Lobe is separated from the Parietal Lobe by a fairly regular sulcus (Central Sulcus) which passes vertically and slightly obliquely through the central portion of the hemisphere.
The Temporal Lobe is separated from the Frontal & Parietal Lobes by the deep Transverse Fissure which continues posteriorly as an imaginary line which intersects the middle of the occipital-parietal line.
The Occipital Lobe is separated from the Parietal and Temporal Lobes by an imaginary vertical line passing between the Preoccipital Notch or indentatation and the Parieto-occipital Sulcus which starts at the superior surface then extends inferiorly on the medial surface.
