Difference between Parietal, Occipital and Temporal Lobe

Parietal Lobe

It is one of the four major lobes of the cerebral cortex region of the mammalian brain. It is positioned behind the frontal lobe and above the temporal lobe. It integrates spatial sense, navigation and other sensory information. The sensory inputs from the skin are relayed to this lobe via the thalamus. Also, the parietal lobe plays a vital role in language processing. The parieto-occipital sulcus divides the parietal from the occipital lobes. Likewise, the lateral sulcus separates it from the temporal lobe.

Occipital Lobe

It is one of the four major lobes that acts as a visual processing centre. There are two small occipital lobes that form a part of the posterior cerebrum. It senses all the information that comes through our eyes. The lobe also has a primary visual cortex to interpret that information.

Temporal Lobe

The temporal lobe lies just beneath the lateral fissures. It occupies both cerebral hemispheres of the brain. This lobe, along with the hippocampus, plays a vital role in the formation of long-term memory. It also processes sensory inputs (both visual and auditory), and aids in the appropriate retention of memories.

Frequently Asked Questions on Difference between Parietal, Occipital and Temporal Lobe

What is a Frontal lobe?

It is the largest lobe that is located in front of the parietal and temporal lobes. It has most of the dopamine neurons in the cerebral cortex. It plays a vital role in managing voluntary movements, and is thus called the ‘action cortex’ region.

What is a sulcus?

It is a deep groove or fissure in the cerebral cortex region. It creates a fold-like appearance in the human brain along with the gyri. Gyri are ridges in the cortex region.
