Parietal lobe function

There’s much to learn regarding the parietal lobes, such as their function and location. The parietal lobes are responsible for sensory information, visual processing, and coordinating movement, and their responsibilities don’t end there. Parietal lobes play a crucial role in many daily activities; without them, we would not be able to distinguish one object from the next. In addition, we would have difficulties with reading, writing, mathematics, and navigation. What Is the Parietal Lobe? There are two parietal lobes: the left and right parietal lobe. Each lobe has its own responsibilities. What Does the Parietal Lobe Do? The left parietal lobe is associated with tracking certain body parts as they move. In contrast, the right parietal lobe keeps track of the environment around us. Overall, the parietal lobes are responsible for more than just tracking movement. Other parietal lobe functions include: • Sensory input • Spatial mapping and attention • Visuospatial processing • Reading • Mathematics The parietal lobes are often split into two functional groups: sensation and perception and sensory input. During sensation and perception, sensory information is integrated and developed into cognition. Sensory input, on the other hand, is an aspect of vision and helps create spatial maps of the world around us. Where Is the Parietal Lobe Located? The parietal lobes are located in the brain, sitting above the temporal lobes and between the frontal and occipital lobes. Parietal L...

Your brain’s parietal lobe is a key part of your understanding of the world around you. It processes your sense of touch and assembles input from your other senses into a form you can use. Your parietal lobe also helps you understand where you are in relation to other things that your senses are picking up around you. Overview The parietal lobe is a major sensory processing hub for your brain. It also combines information from multiple senses into a usable form. In essence, it helps construct the way your brain understands the world around you. What is the parietal lobe? Your parietal lobe is one of your brain’s five lobes. This part of your Function What does the parietal lobe do? Your brain’s parietal (pronounced “pa-RY-ah-tul”) lobe handles a few different jobs. Self-perception Your parietal lobe is a processing center for sensations you can feel with your sense of touch. These include temperature (hot and cold), pressure, vibration and pain. Self-perception also uses your sense of touch to tell you where parts of your body are without needing to see them (the technical term for this is “proprioception”). A good way to test this is to close your eyes and bring the palm of your hand up to your face. Even with your eyes closed, you can usually tell the approximate position of your hand (and avoid smacking yourself in the face). Sensory integration Other brain areas process sensory information they’re responsible for, and then forward what they processed to your parietal l...

Neuroscientists have long divided the brain into four distinct lobes. Originally this division was based solely on the location of the lobes within the skull, but we now know that each lobe carries out a number of highly specialized functions. The parietal lobe is located just under the parietal bone of the skull. This important brain lobe helps integrate sensory input and process language. Where is the Parietal Lobe Located? The brain is divided into a number of regions , but the area most humans refer to when they discuss the brain is the cerebral cortex, or cerebrum. This evolutionarily new region of the brain is present in all mammals, and is what allows complex thoughts rather than just automatic and unconscious processes. Neuroscientists divide the cerebrum into four distinct lobes: parietal, frontal, temporal, and occipital. Because the brain is also divided into right and left hemispheres, each lobe has two separate regions. Thus the parietal lobe can be further divided into the left and right parietal lobes. The parietal lobe rests near the top and center of the cerebral cortex, just behind the frontal lobe and above the occipital and frontal lobe , while the lateral sulcus—sometimes referred to as the Sylvian fissure —separates it from the temporal lobe. The parietal lobe's two hemispheres are divided by the medial longitudinal fissure. What is the Function of the Parietal Lobe? The parietal lobe is vital for sensory perception and integration, including the mana...

The parietal lobe is one of the brain’s major lobes, roughly located at the upper back area in the skull. It processes sensory information received from the outside world, mainly relating to touch, taste, and temperature. Damage to the parietal lobe may lead to dysfunction in the senses. There are also some health conditions associated with parietal lobe damage. Keep reading to learn more. Click on the BodyMap above to interact with a 3D model of the parietal lobe. The parietal lobe is In the brain, the parietal lobe is located behind the frontal lobe. A boundary called the central sulcus separates the two lobes. The parietal lobe also sits above the temporal lobe, with the Sylvian fissure, or lateral sulcus, separating the two. The occipital lobe is behind and slightly underneath the parietal lobe. The parieto-occipital sulcus divides these two lobes. Like the brain itself, the parietal lobe is divided into two hemispheres by the central furrow, or medial longitudinal fissure. The parietal lobe relies heavily on many other areas of the body to receive information. For example, the skin and nerves in the skin play a large part in detecting sensory information and delivering it to the parietal lobe. The parietal lobe itself also sends this information to other parts of the brain for interpretation. Many everyday functions require the use of multiple lobes in the brain. In general, the parietal lobe is a major interpreter of the sensory world around the body. In fact, the pa...

• Focal epilepsies are characterized by seizures arising from a specific part (lobe) of the brain. • Focal epilepsies include idiopathic location-related epilepsies (ILRE), frontal lobe epilepsy, temporal lobe epilepsy, parietal lobe epilepsy and occipital lobe epilepsy. • Focal epilepsy may be treated with medication, and occasionally with diet, nerve stimulation or surgery, especially if the condition is due to a scar or other lesion in the brain. Idiopathic Localization-Related Epilepsies (ILRE) The cause of these localized (focal) seizures is not yet known, but some research points to a genetic component. The person’s brain and brain function may appear normal. Treatment for these epilepsies starts with anticonvulsant medications. Frontal Lobe Epilepsy Frontal lobe epilepsy is the term for recurring seizures beginning in the frontal lobe — the area of the brain behind the forehead. Because the frontal lobe is responsible for planning and executing movement and personality, frontal lobe epilepsy can have a dramatic effect on a patient’s quality of life. Frontal lobe seizures are often very brief (less than 30 seconds) and tend to occur at night. They are typically simple or complex partial seizures and can quickly spread throughout the brain. Because there are so many connections between the frontal and temporal lobes, it can be difficult to determine which section of the brain is being affected. Anticonvulsant medications are the most common first choice for treatment;...

A stroke in the parietal lobe can affect the brain’s ability to interpret sensory information and spatial awareness. As a result, parietal lobe stroke patients often struggle with piecing together their experiences. This article will explain everything you need to know about parietal lobe stroke. Although every stroke is different, we hope this guide helps paint a picture of what the road to recovery may look like. When Stroke Affects the Parietal Lobe A stroke in the parietal lobe occurs when a blood vessel in the parietal lobe either gets clogged by a blood clot (an ischemic stroke) or the blood vessel bursts (a hemorrhagic stroke). Oxygen fuels cell activity. Without enough blood supply, brain cells will start to die, and the parietal lobe will begin to lose control of its function. Immediate medical attention is essential for reducing disability and the other effects of parietal lobe stroke. Like most other Secondary Effects Depend on the Hemisphere Affected A parietal lobe stroke will primarily affect sensory interpretation and spatial awareness. However, effects of the stroke will greatly depend upon the side of the brain that the stroke occurs: your dominant or non-dominant side. Everyone has a dominant side of the brain. If you’re left-handed, the right side of your brain is probably dominant, and if you’re right-handed, the left side of your brain may be dominant. However, the connection between handedness and brain dominance is somewhat controversial and not well...
