What is the parietal lobe and what is it's function?

What is the parietal lobe and what is it's function?

Part of brain: It is part of brain positioned above the occipital lobe and behind the frontal lobe.
Its function is to integrate sensory information from the visual cortex. It includes infomation processing related to the sense of touch. So it is involved in visuospatial processing. It is also involved with language processing. ...Read more

Lobe (Definition)

1. A rounded projection, especially a rounded, projecting anatomical part. (for example, the lobe of an ear) 2. A subdivision of a bodily organ or part bounded by fissures, connective tissue, or other structural boundaries. (for example, a ...Read more

I was wondering does the parietal lobe affect our sense of touch?

Integration center: Parietal lobe provides localization, timing, and integration of incoming brain data, and gives us perspective on the outside world. Regarding sense of touch, it allows simultaneous perspectives, and perception of location of the touch, including intensity of sensation. ...Read more

Does the body lose all sensation if the parietal lobe stopped functioning?

Does the body lose all sensation if the parietal lobe stopped functioning?

NO!: All sensations are organized and responded by THALAMUS Only cortical sensation s are controlled by the parietal lobes (2 point discriminationn, stereognosis i.e. the shape of objects, also the weight of objects) ...Read more

What role does the dominant parietal lobe have in speech and speech formation?

What role does the dominant parietal lobe have in speech and speech formation?

Critical: Dominant speech pathways connect via the arcuate fasciculus, and connect expressive centers in frontal broca's area to receptive regions in the temporal lobe. ...Read more

Sharp pain in temporal parietal lobe?

Sharp pain in temporal parietal lobe?

Impossible: You cannot have a pain in your temporal or parietal lobe. Your brain has no pain nerves. All sensations are processed in the brain but experienced elsewhere in the body. Whatever pain you're feeling, it's not in your brain tissue. ...Read more

Do hemineglect, hemiplegia occur from damage to the parietal lobe?

Do hemineglect, hemiplegia occur from damage to the parietal lobe?

Yes: Contralateral weakness can be present. Sensation is altered on the same side, and pts have trouble localizing motion in time and space. Extinction phenomena occur, position sensation can be lost, the affected limb may not be recognized or even thought to be part of another person. ...Read more

On an EEG- What does it mean if you had "longer than normal recovery from HV" and spikes & slowing in parietal lobe??

EEG Abnormal: Hi Nicole,
It would help knowing why you had the EEG. I am not so worried about the "HV" recovery but the spikes and slowing in the left temporal lobe is not normal and suggests that you might have epilepsy or s structural brain lesion and should have an MRI of the brain. This should be discussed with your doctor.
Hope that helps,
-Dr Safdieh ...Read more

Dent from car crash, on top of head in parietal lobe, had over 10 years no problems, just curious, 1-2 inch wide?

Dent from car crash, on top of head in parietal lobe, had over 10 years no problems, just curious, 1-2 inch wide?

Yikes: I guess if you have not had trouble with it in several years, it is unlikely to cause trouble now. What you are describing would be concerning for a displaced skull fracture, but again, it has been several years now since the accident. A ct skull would undoubtedly give more information and I would recommend you being seen if you are concerned. ...Read more

My son had a syncopal episode with a concussion. He had major swelling on the top of his head (parietal lobe). He cannot smell/taste. Will it return?

My son had a syncopal episode with a concussion. He had major swelling on the top of his head (parietal lobe). He cannot smell/taste. Will it return?

Should improve: If this was a concussion and there was no fracture of the cribiform plate, the loss of smell and taste is not uncommon nor is it unusual. This has a good chance of improving over time. It may take 6-12 weeks. ...Read more

My mom 52 yrs of age with no underlying condition has been diagnosed with meningioma in left parietal lobe along the falx of the size 4.6 X 4.5 X 4 cm?

My mom 52 yrs of age with no underlying condition has been diagnosed with meningioma in left parietal lobe along the falx of the size 4.6 X 4.5 X 4 cm?

May need tx: Does your mom have symptom? Symptomatic meningioma >4cm generally requires tx. Asymptomatic meningioma > 4cm usually will be treated, or observed occationally according to the NCCN. Tx will involve surgery if accessible, followed by radiation depending on the pathology or may be radiation alone. You should see an oncologist to have a thorough review of the case and then decide. ...Read more

Calcification of a lesion in the left parietal lobe along the falx no symptoms except occasional focal fit?

Calcification of a lesion in the left parietal lobe along the falx no symptoms except occasional focal fit?

Probably from pork: Cysticercosis is an infection by the pork tapeworm (Taenia solium). Infected people may have no symptoms for years, then if a cyst of the tapeworm forms in the brain, it is one of the most common causes of seizures. In some parts of the world up to 1/4 of the people have cysticercosis. Avoid eating pork to prevent more cysts from forming in your body. The best diet for humans is eating plants. ...Read more

What can you tell me about living with both parietal lobe epilepsy and hemiplegic migraines?

What can you tell me about living with both parietal lobe epilepsy and hemiplegic migraines?

Try prevention: There are medications which may help prevent both seizures and migraine headaches and two to consider are topirimate and depakote, both with fda indications. Some other anti-seizure meds maybe similarly useful. Your neurologist can help guide you. ...Read more

Chronic periventricular white matter focus left parietal lobe. The etiology is non specific in nature? There were finding in MRI. Meaning!?

Chronic periventricular white matter focus left parietal lobe. The etiology is non specific in nature? There were finding in MRI. Meaning!?

Good question: At this time MRI is very sensitive to any type of damage or changes in tissue but we still have to go by pattern recognition to diagnose anything. This is the reason the read says "non specific". One lesion doesn't mean anything unless it fits a pattern. We see this all the time and it is considered a normal variant meaning it is not normal but found in enough people to be considered normal. ...Read more

I had a traumatic brain injury with damage to the right inferior frontal lobe and left parietal lobe. What are possible effects?

I had a traumatic brain injury with damage to the right inferior frontal lobe and left parietal lobe. What are possible effects?

Hard to say: It is hard to say. From your question, it sounds as though you had injury demonstrated either by ct scan or MRI scan. One may have no problems at all, it depends on the size of the injury and the exact location in these regions. If you are asking what these areas typically do: r frontal: smell, memory, impulse control, left sided movement. L parietal: speech, language, right sided movement. ...Read more

A palpable, non-moving protrusion from top-back of my skull (parietal lobe) of size 3 cc. No headaches or other symptoms. Could it be a tumor?

A palpable, non-moving protrusion from top-back of my skull (parietal lobe) of size 3 cc. No headaches or other symptoms. Could it be a tumor?

Could be anything: I'd be interested to know if this is new or something you had all your life. Could be as simple as a bony protrusion of your skull that has been there from the beginning but any new lump that persists or grows should be evaluated by a physician. Have it checked and best to you. ...Read more

Have throbbing pain in left parietal lobe. Began less than 24 hours ago but will not go away. Stops for short time then starts again. Brain tumor?

Have throbbing pain in left parietal lobe. Began less than 24 hours ago but will not go away. Stops for short time then starts again. Brain tumor?

A wee clarification: 1) You cannot have a pain in your left parietal lobe. Your brain has no pain nerves. All sensations are processed in the brain but experienced elsewhere in the body. 2) The brain has no connective tissue. Lots of connective tissue around the brain, however: Meninges, arterial sheaths, other connective tissue, all of which is exquisitely sensitive to pain. That's what pains and throbs. ...Read more

Neurologist not sure if its sporadic hemiplegic migraines or right sided-parietal lobe seizures. How can I know which it is if even he's not sure?

2nd Opinion?: Some neuro diseases are very difficult to tell apart. Many diseases have similar symptoms and present the same way on tests. You could always try getting a 2nd opinion from a different neurologist. A sleep deprived eeg or an ambulatory eeg should help sort this out. ...Read more

What do you mean by: 1. Scalp hematoma, left parietal region 2, cerebral contusion left parietal lobe 3. Cerebral contusion left base cerebral hemisph?

What do you mean by: 1. Scalp hematoma, left parietal region 2, cerebral contusion left parietal lobe 3. Cerebral contusion left base cerebral hemisph?

Scalp hematoma: Scalp hematoma is a bleeding underneath the scalp in the upper left region of the skull. The contusion is in the same region and is a brusing and bleeding in the brain. #3. Is another bruising or bleeding on the left side of the brain but lower down towards the base of the skull. These injuries sound like there are a result of head trauma. ...Read more

I got a nose bleed the other night after having a headache in the back of my eyes and a top my parietal lobe and down to the temporal lobe?

Nose bleed: An occasional nose bleed is not be concerned about. For good health: Have a diet rich in fresh vegetables, fruits, whole grains, low fat milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco or alcohol in any form. ...Read more

Am 48 years old and am diabetic and hyper tense. My brain mri says lacunar infarct in periventricular white matter of right parietal lobe. What is this?

Small stroke: This means that you have had a small stroke in the deep brain tissue. It does not mean that you will necessarily have deficits from this but it does mean that you need to control your sugars and blood pressure very carefully to prevent further damage. It is also important to not smoke and to have a healthy diet and drink at least 2 liters of water daily. You should take an aspirin daily also. ...Read more

I am 22 year old female. I am suffering from shaky right hand and leg. Mri report says calcified granuloma in the left parietal lobe likely Neurocysti?

Cysticercosis: Infection by the pork tapeworm, Tanea solium, can cause cysts within the brain. The reading on your MRI does suggest this process, and the symptoms on the right side of your body fits with the left parietal lesion. You may be having focal seizures, and an anti-epileptic drug may well help. A neurologist needs to get involved. ...Read more

After major stroke that affected 3 lobes on left brain due to 100% blockage of coroided how will this effect my life expectancy?

After major stroke that affected 3 lobes on left brain due to 100% blockage of coroided how will this effect my life expectancy?

Depends: Carotid arterial disease is a strong marker for heart disease. Your life expectancy will depend on the co-morbid disease you have: especially in your heart, which should be evaluated after you've sufficiently recovered from your stroke. Good luck, my friend. ...Read more

Is anger common after a stroke involving the frontal lobe of the brain? And can it be a permanet

Is anger common after a stroke involving the frontal lobe of the brain? And can it be a permanet

Stroke and mood: Yes! Frontal lobe strokes can cause personality and/or mood changes. The FLs when healthy act as our "filter", keep us from losing control of our emotions, help us maintain attention, among other things. Damage to certain frontal areas can cause difficulty controlling anger, tendency to be 'black and white' in your thinking, or even depression. Yes these can be permanent, but also can be treated.. ...Read more

I have a two cm. Cyst in my frontal left lobe of my brain. My grandmother had an anyurism and stroke. Am I at a higher risk than most because of this?

I have a two cm. Cyst in my frontal left lobe of my brain. My grandmother had an anyurism and stroke. Am I at a higher risk than most because of this?

Probably not: The 2 cm cyst in your head/brain is presumably an arachnoid cyst and is not itself a risk factor for aneurysm. There is likely a hereditary component to some aneurysms, and often screening is done for people who have a first degree relative (i.e., parent, sibling, child) with an aneurysm. Having a single grandmother with an aneurysm likely does not increase your risk much if at all. ...Read more

My brother has old infract frontal and temporo parietal lobe please tell the treatment?

Old stroke: Treatment is likely based on cause and residual problems. If this was due to trauma, arterial dissection, or an embolism, the approach should vary. Some strokes are secondary to heart issues. Generically, antiplatelet drugs might be preventative if future risk, and weakness or imbalance due to the stroke could benefit from pt, ot, and speech therapy. ...Read more
