It is primarily responsible for sensations of touch, such as temperature and pain, but it also plays a role in numerous other functions.
A number of conditions can occur due to dysfunction in or injury to the parietal lobe. The human brain is a hugely complex organ, made of different areas that handle different functions.
The cerebellum is the part that handles many…. Brain function and memory naturally decline slightly as a person ages, but there are many techniques people can use to improve memory and prevent its…. The frontal lobe is a part of the brain that controls key functions relating to consciousness and communication, memory, attention, and other roles…. Ataxia is a lack of muscle coordination that can make speech and movement difficult.
It may develop due to genetic factors, alcohol use, or injury. Creutzfeldt-Jakob disease CJD is a rare neurodegenerative condition that gradually destroys brain cells. In most cases, the cause is unknown. All about the parietal lobe. Medically reviewed by Nancy Hammond, M. Definition Function Anatomy Linked conditions Summary The parietal lobe is one of the major lobes in the brain, roughly located at the upper back area in the skull. What is it? Linked medical conditions.

Everything you need to know about the cerebellum Medically reviewed by J. Keith Fisher, M. How to improve your memory: 8 techniques to try. Medically reviewed by Timothy J. In addition to being divided into left and right hemispheres, the parietal lobe has a number of distinct structures, each with its own unique contribution to brain functioning.
Those structures include:. It is a myth that any single brain region controls any function. Rather, each region of the brain works in conjunction with the body. Without the environment, the brain could do little or nothing, and the parietal lobe is no exception. Its role in sensory processing means that the parietal lobe depends on a cascade of sensory input from all over the body, including the eyes, hands, tongue, and skin.
These disparate regions cannot function without the input of the parietal lobe, which assigns meaning to the sensory input you encounter each day. The parietal lobe also sends signals to and receives signals from other brain regions, most notably the occipital lobe. The occipital lobe aids the parietal lobe in visual perception and processing, as well as spatial navigation and reasoning. Though each brain region has a specific set of functions, many of these functions are interchangeable and cross brain regions.
Every brain region, for instance, is vital for language processing. Some research has also found that, when there is damage to one region of the brain, nearby regions may compensate, particularly if an injured person receives immediate and comprehensive occupational and physical therapy. Because of the parietal lobe's role in sensory integration, spatial reasoning, and language skills, damage to the parietal lobe can have a broad range of consequences.
The specific prognosis depends in large part on the location of the injury, the severity of the injury, and whether the injury can be treated. For instance, a lesion pressing on the parietal lobe will have a better prognosis with improved functioning if the lesion can be removed.
Quality medical care is incredibly important, particularly when that care includes comprehensive physical, occupational, and speech therapy. Appropriate treatment can help your brain learn to work around the injuries, and may even aid other brain regions to compensate for those injuries.
Your age, nutritional status, overall health at the time of the injury, and commitment to a healthy lifestyle are also important.
A healthy person who continues exercising and trying novel strategies is much more likely to recover than someone with ongoing cardiovascular problems who is unwilling to try new strategies or embrace lifestyle remedies.
Spinal cord injuries are traumatic for patients and their families. They cause disruptive changes to every aspect of your life and there is a lot of new information to navigate and understand.

Parietal Lobe: Function, Location and Structure The parietal lobe receives and manages sensory input and is located just under the parietal bone of the skull. It results from damage to the areas of the brain that control language. People may have People who lose their inhibitions may be inappropriately elated euphoric or depressed, excessively argumentative or passive, and vulgar.
They may show no regard for the consequences of their behavior. They may also repeat what they say. Some people develop similar symptoms when they get older or if dementia develops. These symptoms may result from degeneration of the frontal lobe. Different areas of the brain control specific functions.
Consequently, where the brain is damaged determines which function is lost. Storing spatial memories that enable people to orient themselves in space know where they are and to maintain a sense of direction know where they are going.
Certain functions tend to be controlled more by one of the parietal lobes usually the left. It is considered the dominant lobe when it controls language. The other lobe nondominant has other functions, such as enabling people to be aware of how the body relates to the space around it. Damage to the front part of the parietal lobe on one side causes numbness and impairs sensation on the opposite side of the body. People may have difficulty recognizing objects by touch that is, by their texture and shape.
If the middle part is damaged, people cannot tell the right from the left side called right-left disorientation and have problems with calculations and writing. They may have problems sensing where parts of their body are a sense called proprioception. If the nondominant usually right parietal lobe is damaged, people may be unable to do simple skilled tasks, such as combing their hair or dressing—called apraxia Apraxia Apraxia is loss of the ability to do tasks that require remembering patterns or sequences of movements.
People with apraxia cannot remember or do the sequence of movements needed to complete They may also have trouble understanding how objects relate to each other in space.
As a result, they may have trouble drawing and constructing things, and they may get lost in their own neighborhood. These people may also ignore the serious nature of their disorder or deny its existence. They may neglect the side of the body opposite the brain damage usually the left side. Comprehending sounds and images, enabling people to recognize other people and objects and to integrate hearing and speech.
In most people, part of the left temporal lobe controls language comprehension. If that part is damaged, memory for words can be drastically impaired, as can the ability to understand language—an impairment called Wernicke receptive aphasia Wernicke-Korsakoff Syndrome Wernicke-Korsakoff syndrome is an unusual form of amnesia that combines two disorders: an acute confusional state Wernicke encephalopathy and a type of long-term amnesia called Korsakoff syndrome If certain areas of the right temporal lobe are damaged, memory for sounds and music may be impaired.
As a result, people may have trouble singing. When the spinal cord is affected due to disease or trauma, functional difficulties might appear. The resulting effects on the body depend on the location of injury to the spinal cord. In the brain, the location of the injury will affect how the body works and how thinking occurs. Brain injury is a common partner to spinal cord injury.
Even though an injury to the brain can affect just that one spot, the brain is intertwined in its functioning. An injury to one part can affect other parts of the brain and the entire nervous system.
There are basically six parts of the brain. Each part contains important structures. This information is a very general overview of the basic functions of the parts. Neuropsychological testing can isolate specific areas of the brain that are affected by injury thereby tailoring a specific treatment plan. Frontal Lobes The frontal lobes of the brain are located just as they are titled, right up in the front of the skull behind the forehead.
They extend about halfway toward the back of the head and down the side of the head to about the level of your eyebrows. There are two lobes that sit next to each other, the left and the right side.
This part of the brain is often called the mother because it governs your actions just as your mother would stop impulsive or antisocial actions. The frontal lobe is responsible for emotional, social and sexual control, attention, motivation, judgment, spontaneity, problem-solving, and sequencing.
It also handles verbal expression, motor integration, voluntary movement, and sequencing. Personality changes can occur with frontal lobe injury. These can be brief or long-lasting. Medications can be prescribed if behavior becomes aggressive or threatening.
Injury to one or both frontal lobes is often seen as difficulties in social and behavioral situations. All therapies and nursing are included in treatments for frontal lobe injury.
Treatments include reeducation about reactions to situations which might be practiced before entering the real situation. For instance, in a therapeutic session, the patient may be presented with pictures or enactment of a situation followed by the patient responding. The individual is then guided to an appropriate response if needed.
Other therapies might include practice in ordering activities such as putting socks on before shoes if that is an issue for the individual. Choices can be encouraged when the individual is recovered enough to do so. It is important to follow the instructions of your healthcare professionals when providing care for the individual with a frontal lobe injury.
They are in the best position to indicate which techniques should be used and when to advance options. Your input about how you are feeling and responding to therapy should be considered.
