Brain mapping is a technique where the biological quantities of a human brain are represented as spatial quantities resulting in maps. As with many other medical technologies, brain mapping is fast-evolving as well. Among several uses, brain mapping is chiefly used while performing surgery on the brain.
When surgery is to be performed on the brain such as surgery for epilepsy, the surgeon would want to comprehend how the brain areas are affected by seizures. The surgical intervention is meant for removing as much as seizure focus as possible while preserving crucial functions like understanding, speech, vision, movement, and sensation.
Why is brain mapping performed?
Brain mapping is a process which helps in identification of functions of various parts of the brain. Mapping the brain by stimulating different areas of the brain areas can aid in creating a map for a particular person. The map allows the doctor in understanding what parts of the brain are responsible for performing critical functions including sensation, movement, speech and other functions.
Which functions of the brain can be mapped electrically?
Typical areas of the brain which have motor, language, visual and sensory functions are needed to be mapped. When current is applied to a single area at a time, the doctor understands which part of the brain is responsible for which function.
When the patient is not able to speak due to the current, then the area is likely to be crucial for language function. If the limbs, face or trunk of the patient stop moving as the current passes, the area that is tested is responsible for movement. On the other hand, if the individual experiences tingling, numbing, and other sensations when the current is applied, it means that a sensory region is discovered.
How is electrical brain mapping performed?
Electrical brain mapping for guiding brain surgery for epilepsy can be performed in two distinct processes: directly during the surgery or in a two-stage procedure.
In the first stage of the process, the surgeon creates an opening in the skull which helps in exposing the surface of the brain. Small electrical contacts or electrodes are placed on the brain surface even though no brain tissue is removed. As soon as the electrodes are in the right position, the scalp is closed. The electrodes not only record the seizure of the patient electrically but also allow mapping of various areas of the brain. The last stage is surgery where abnormal brain tissues are removed.
Brain mapping process during surgery:
Electrical brain mapping may also be performed during the surgery which exposes part of the brain. This is termed as intraoperative brain mapping since it occurs while performing the main operation. The process of mapping may last for an hour to several hours at a stretch.
Brain mapping is also used to diagnose neurodegenerative diseases like Alzheimer’s and Parkinson’s. In these cases, the brain map shows extreme shrinkage of the brain due to tissue loss. If you wish to discuss about any specific problem, you can consult a Neurosurgeon.
This is a form of epithelial cancer and is a lose called eating cancer
Symptoms:- it first appears on the nose as a hard, dusky red sore and spreads in ulcerative form destroying the tissues till the bones are exposed. This affect women 10 time more than men. It usually appears in women between the age. Nausea, vomiting and abdominal pain may accompany. It is an ulcerative skin disease and requires a very long-term treatment. Sensitivity to sunlight is usually present. Lupus is caused by disruption of body waste disposal system from failure of special enzyme d nasil, which fails to remove wastes from the body.
The disease is easily noticeable as it is outside the body on the the skin and biopsy is performed to confirm it.
If possible, the affected portion of the body is cut out.
I suggest homoeo doctor consult and homoeo treatment best.
Uterine fibroids are referred to as benign, abnormal growths which tend to develop in the uterine walls of a woman. The size of such growths can range from a few centimeters to even excess of a few inches. As such, they can cause the uterus to increase to the size of a five month pregnancy. Although, the symptoms of fibroids are not always apparent, they often cause heavy bleeding and pain in women. A recent research concluded that around 60 to 75 percent women contract such fibroids by the age of 50, at least once in their life.
Depending on the site of formation, uterine fibroids are distinguished into different types. Intramural fibroids in the lining of the uterus and subserosal fibroids which develop outside the uterus are the most commonly observed fibroids.
What causes Uterine Fibroids?
Although, the exact reason for the formation of fibroids are obscure, medical professionals have determined certain factors that may affect their formation. Some of them are:
1) Hormones: Progesterone and estrogen, produced by the ovaries regenerate the uterine lining during each menstrual cycle and trigger the growth of fibroids.
2) Family history: If you have had a family history of uterine fibroids, then you're likely to develop the condition yourself as well.
3) Pregnancy: The production of progesterone and estrogen increases during pregnancy which increases the likelihood of fibroids.
What are the signs of the condition?
Depending on the location and size of the tumors, symptoms of such fibroids include:
1) Heavy bleeding and blood clots during periods
2) Pain in the pelvis
3) Frequent menstrual cramps
4) Pressure and pain in the lower abdomen
5) Swelling in the abdomen
6) Pain while intercourse
What is the procedure of the treatment?
Ultrasound and pelvic MRI are common diagnostic procedures to check for uterine fibroids. After diagnosis, depending on your age, size of the fibroid and your comprehensive health, the doctor would prescribe you with appropriate medications. Only after medications prove futile, doctors opt for minimally invasive surgeries. If you wish to discuss about any specific problem, you can consult a doctor and ask a free question.

Breast cancer is a type of cancer, which occurs due to the development of cancerous cells in breasts. Women are usually affected by breast cancer and breast cancer is one of the most common forms of cancer after skin cancer. Usually fatal if not diagnosed in its early stage, breast cancer is a very serious medical ailment. Read on more to find all about the different symptoms, causes, preventive measures and treatment of breast cancer.
Symptoms: Breast cancer has few distinct characteristics and if you have a few or all the following symptoms you could be more likely to suffer from breast cancer.
- The formation of a lump in your breast, which is different from the surrounding tissue and usually more thickened.
- The discharge of bloody fluid material from the nipples.
- Sudden change of the size, shape and appearance of the breast.
- Certain distinct changes to the skin over the breast for example an indentation in the skin similar to that of a dimple.
- Appearance of an extra nipple which is inverted.
- If the darkened area around the nipples known as the areola is flaking or peeling off.
Causes: Studies and researches remain inconclusive on what causes breast cancer. Breast cancer occurs due to abnormal division of the cells located in the breast, which over time accumulate and form lumps. They
might spread to other parts of the body. Breast cancer is caused mainly due to a complex interaction of personal genetics, environment and lifestyle choices. Breast cancer can also be caused due to genetics as about 5% to 10% of cases are due to gene mutations which pass onto generations.
Risk factors: There are certain factors, which increase the probability of contracting breast cancer. Increasing age, personal and family history of breast cancer, obesity, radiation exposure, pregnancy at an older age, postmenopausal hormone therapy are some of the factors that increase the chances of breast cancer.
Treatment: Several forms of surgical methods exist to treat breast cancer. Depending on the condition and spread of the disease a suitable surgery is performed. These include mastectomy, lumpectomy, axillary lymph node dissection and removal of both breasts. Other forms of treatment include chemotherapy or the use of high doses of drugs to destroy cancerous cells. Radiation therapy where X-rays are used to destroy the cancer cells is also effective.
