Understanding Parietal Lobe Function: What Happens When this Important Brain Region is Damaged?

The human brain consists of several regions, each having its own unique function. One essential part of the brain is the Parietal Lobe. It is located at the top and the back of the head, behind the frontal lobe and above the occipital lobe.

In this blog post, we’ll be exploring parietal lobe function psychology. We’ll cover topics like parietal lobe damage, right frontal parietal lobe function, temporal lobe function, and occipital lobe location. By the end of this post, you’ll have a comprehensive understanding of the parietal lobe function, its importance, and how its damage impacts the brain.

What is the Parietal Lobe and Where is it Located?

As noted earlier, the parietal lobe is situated at the top and the back of the head. It is also known as the third lobe, located in the posterior area of the brain. The lobe is a part of the cerebral cortex, which is the most significant part of the brain and is responsible for higher mental functions like language, decision making, and memory.

The Parietal Lobe receives sensory information from different parts of the body and processes this information to give us a sense of our environment’s spatial orientation. This means that the lobe is crucial in helping us understand our body’s position in space and time.

What are the Functions of the Parietal Lobe?

The Parietal Lobe is responsible for several essential functions in the body. Here are some of the most critical functions controlled by the parietal lobe:

1. Spatial Processing

The Parietal Lobe is responsible for processing spatial information from various senses, including touch, hearing, and vision. This assists in interpreting the positioning of objects in space. For instance, imagine trying to fit two puzzle pieces together without looking at them. You’d only be able to do this using your sense of touch and spatial processing abilities.

2. Sensory Processing

The parietal lobe plays a significant role in processing a variety of sensory inputs. This includes information related to touch, pain, temperature, and pressure. The lobe also helps process visual information related to depth perception, visual-spatial perception, and object recognition.

3. Perception

The Parietal Lobe works alongside other areas of the brain to create a complete picture of the world around us. It helps us to perceive and understand the visual cues in our environment. By doing this, we can evaluate our position in the world and develop a better sense of proprioception.

What Happens if the Parietal Lobe is Damaged?

Brain damage can occur due to various factors like accidents, stroke, or tumors. When the Parietal Lobe is damaged, the individual may experience a range of symptoms depending on the lobe’s extent of damage.

Here are some of the potential effects of Parietal Lobe damage:

1. Sensory Deficits

Due to the role of the Parietal Lobe in sensory processing, damage to this region can cause a range of sensory deficits. For instance, individuals may experience difficulty recognizing different colors or perceiving depth.

2. Problems with Spatial Perception

The Parietal Lobe is responsible for our ability to interpret spatial information, so if it’s damaged, it can significantly impact a person’s ability to understand spatial information. This may lead to difficulties with navigation, reading maps, and even finding one’s way home.

3. Difficulty with Mathematical Problems

The Parietal Lobe also plays an essential role in mathematical problem-solving. Therefore, damage to this region may cause difficulty with complex calculations, mathematical manipulation, and understanding abstract mathematical concepts.

How are Other Brain Regions Connected to the Parietal Lobe?

The Parietal Lobe communicates with other parts of the brain to carry out its various functions. Here are some examples:

1. The Occipital Lobe

The Occipital Lobe is responsible for vision, and it communicates with the Parietal Lobe to help interpret information about objects’ positions.

2. The Temporal Lobe

The Temporal Lobe is responsible for hearing, and it also communicates with the Parietal Lobe to process auditory information and guide sound localization.

3. The Frontal Lobe

The Frontal Lobe is responsible for executive functions like decision-making, complex planning, and attention. It interacts with the Parietal Lobe to provide information on the spatial processing required to execute complex tasks successfully.

Examples of Parietal Lobe Function

Now that we’ve explored the role of the Parietal Lobe and the effects of its damage, let’s take a look at some examples of the Parietal Lobe at work:

Example 1: Playing a Musical Instrument

When playing an instrument, a musician must read sheet music, process spatial information, and execute complex movements. The Parietal Lobe is responsible for coordinating these functions, making it integral to the process.

Example 2: Playing Sports

Athletes rely on their Parietal Lobe to process spatial information and plan their movements. Whether it’s throwing a ball, playing soccer, or running track, successful athletic performance requires a working Parietal Lobe.

Example 3: Driving a Car

When driving, the Parietal Lobe helps drivers to process visual and spatial information, navigate, and plan movements. When the Parietal Lobe is damaged, it can create difficulties when driving due to the lack of spatial processing.


In conclusion, the Parietal Lobe is an essential region of the brain responsible for various functions like spatial processing, sensory processing, and perception. Damage to the Parietal Lobe can have a significant impact on a person’s ability to interpret and perceive data correctly, do complex calculations and perform everyday tasks like driving.

Understanding the Parietal Lobe function psychology and the role it plays in the body is vital to promoting good cognitive health and functioning. It’s crucial to protect this lobe from harm, and if damaged, quick intervention and therapy can help minimize the effects on the individual.
