The human brain is the most complex and least understood part of the human anatomy. There may be a lot we don’t know, but here are a few interesting facts that we’ve got covered.
Nerve impulses to and from the brain travel as fast as 170 miles per hour. Ever wonder how you can react so fast to things around you or why that stubbed toe hurts right away? it’s due to the super-speedy movement of nerve impulses from your brain to the rest of your body and vice versa, bringing reactions at the speed of a high powered luxury sports car.
The brain operates on the same amount of power as 10-watt light bulb. The cartoon image of a light bulb over your head when a great thought occurs isn’t too far off the mark. Your brain generates as much energy as a small light bulb even when you’re sleeping.
The human brain cell can hold 5 times as much information as the encyclopedia britannica. Or any other encyclopedia for that matter. Scientists have yet to settle on a definitive amount, but the storage capacity of the brain in electronic terms is thought to be between 3 or even 1, 000 terabytes. The national archives of britain, containing over 900 years of history, only takes up 70 terabytes, making your brain’s memory power pretty darn impressive.
Your brain uses 20% of the oxygen that enters your bloodstream. The brain only makes up about 2% of our body mass, yet consumes more oxygen than any other organ in the body, making it extremely susceptible to damage related to oxygen deprivation. So breathe deep to keep your brain happy and swimming in oxygenated cells.
The brain is much more active at night than during the day. Logically, you would think that all the moving around, complicated calculations and tasks and general interaction we do on a daily basis during our working hours would take a lot more brain power than, say, lying in bed. Turns out, the opposite is true. When you turn off your brain turns on. Scientists don’t yet know why this is but you can thank the hard work of your brain while you sleep for all those pleasant dreams.
Scientists say the higher your i. q. The more you dream. While this may be true, don’t take it as a sign you’re mentally lacking if you can’t recall your dreams. Most of us don’t remember many of our dreams and the average length of most dreams is only 2-3 seconds–barely long enough to register.
Neurons continue to grow throughout human life. For years scientists and doctors thought that brain and neural tissue couldn’t grow or regenerate. While it doesn’t act in the same manner as tissues in many other parts of the body, neurons can and do grow throughout your life, adding a whole new dimension to the study of the brain and the illnesses that affect it.
Information travels at different speeds within different types of neurons. Not all neurons are the same. There are a few different types within the body and transmission along these different kinds can be as slow as 0.5 meters/sec or as fast as 120 meters/sec.
The brain itself cannot feel pain. While the brain might be the pain center when you cut your finger or burn yourself, the brain itself does not have pain receptors and cannot feel pain. That doesn’t mean your head can’t hurt. The brain is surrounded by loads of tissues, nerves and blood vessels that are plenty receptive to pain and can give you a pounding headache.
80% of the brain is water. Your brain isn’t the firm, gray mass you’ve seen on tv. Living brain tissue is a squishy, pink and jelly-like organ thanks to the loads of blood and high water content of the tissue. So the next time you’re feeling dehydrated get a drink to keep your brain hydrated.

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 awareness
October is breast cancer awareness month and a great time to highlight the importance of maintaining healthy habits to support breast health. One disease that most women fear these days, you would probably reply" breast cancer.
Understand what you can do to reduce your breast cancer risk. So follow these guidelines and know that you are doing all that you possibly can to protect yourself from developing breast cancer. Be thankful every day that your breasts are healthy.
Check your own breasts regularly. Do monthly self-breast examinations after your period is over. If you find any lumps or tenderness that concerns you, have it checked out right away. Fortunately, 80% of breast lumps are benign. When you examine your breasts, remember that lumps which are soft, movable, and change with your menstrual cycle are much less likely to be cancerous. Any discharge from the nipple other than breast milk should be checked out by your health professional.
Get regular mammograms. In a woman without breast symptoms and with no significant risk of breast cancer, I recommend mammograms beginning age 35 or 40 every two years. For women without breast symptoms who are at higher risk of breast cancer, I recommend yearly mammograms beginning at age 35. Beginning at age 50, the rate of breast cancer goes up, so yearly mammograms are advised.
Limit alcohol intake. The more alcohol you drink, the greater your risk of developing breast cancer.
Get to and maintain a healthy weight - if your bmi is out of the healthy range, find a program and tools to help you get to a healthy weight, which is important for maintaining health in general, including breast health. Obesity, particularly after menopause, can greatly increase your risk of breast cancer. Aim for gradual weight loss by choosing minimally processed foods and eating smaller portions.
Don't smoke - accumulating evidence suggests a link between smoking and breast cancer risk, particularly in pre -menopausal women.
Exercise regularly - physical activity can help you maintain a healthy weight, which, in turn, helps prevent breast cancer.
Limit dose and duration of hormone therapy - if you're taking hormone therapy for menopausal symptoms, ask your doctor about other options. You might be able to manage your symptoms with non-hormonal therapies and medications.
Choose the right supplements - filling in nutrition gaps with supplements can help you support breast health. Look for options that contain vitamin d and omega-3 fatty acids, as they have both been associated with maintaining breast health.
Breast-feed your babies for as long as possible - women who breast-feed their babies for at least a year in total have a reduced risk of developing breast cancer later.
Hello, I have very much pain in L5 S1 spine from last 2 months. MRI report says: "Annular tear of l5-s1 disc with diffuse posterior bulge, central & right para central prolapse & mild inferior migration of the prolapsed fragment causing compression of right exiting nerve root. Please suggest me what I do? Pain is very much. Should I go for surgery or any other option available. If surgery then how much time time required to recover & what is accuracy of surgery treatment. Thank you.

Myth: Brain damage is always permanent.
Fact: The brain can repair or compensate for certain losses, and even generate new cells.
People once believed that we were born with a finite number of brain cells, and that was it for life; if you damaged any of them you could never get them back. Similarly, many scientists believed that the brain was unalterable; once it was" broken" it could not be fixed.
Now, of course, we know that the brain remains plastic throughout life, and can rewire itself in response to learning. It can also generate new brain cells under the right circumstances.
Breast cancer is a type of cancer which occurs due to the development of cancerous cells in a person's 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.
Breast cancer has a 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.
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.
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, post-menopausal hormone therapy are some of the factors that increase the chances of breast cancer.
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. If you wish to discuss about any specific problem, you can consult a Gynaecologist.
I am suffering from sciatica for the last 6 months. Tried back exercises and muscle relaxants. The condition is due to L4/L5 disc herniation. Kindly advice.
Q1. What exactly is Laparoscopy?
Laparoscopy is an alternative to 'Open' surgery wherein the abdomen is opened by tiny 'key hole' incisions and surgery is done. 'Scopy' means the use of an endoscope or telescope to see inside the abdomen. This is attached to a camera and a light source and the inside of the abdomen is projected on to a monitor. The surgeon performs surgery looking at this screen. The surgeon makes a total of 2-4 small cuts on the abdomen ranging from half to 1 cm through which the telescope and other thin surgical instruments are passed into the abdomen. When the uterus is removed , known as hysterectomy, there is also a cut at the top of the vagina where the uterus is attached.
Q2. What kind of gynaecological surgeries can be performed by Laparoscopy?
Most surgeries done in gynaecology can now be performed by Laparoscopy and do not require the large incision as for open surgery. Laparoscopy can be done sometimes only for diagnosis and is called Diagnostic Laparoscopy, as in checking whether the tubes are open or not and to look for any causes of infertility or pain outside the uterus. In women who are unable to conceive, Diagnostic Laparoscopy is often combined with Hysteroscopy (endoscope inside the uterus, inserted from below, via the vagina). When laparoscopy is done to perform some surgical procedure inside the abdomen it is called Operative Laparoscopy. This may be for simple procedures like sterilization, minor adhesions, drilling ovaries; or for intermediate or major reasons like fibroids, endometriosis, removal of ovaries or tubes or both or removal of uterus, for staging of cancers or radical surgeries for cancer. However, about 5% of all surgeries including those for cancer or very large tumours may benefit from open surgery.
Q3. Why does an expert surgeon recommend Laparoscopy over Open Surgery?
Laparoscopic surgery has many advantages above open surgery: the incisions are much smaller (open surgery incisions are 8-10 cms long), therefore pain is much less; requirement for pain killers (which can have side-effects like sleepiness, impaired judgement) is lesser; hospital stay is shorter; complications fewer; requirement for blood transfusions infrequent; recovery in terms of physical, emotional and mental state is much better and quicker; return to work is faster with consequent lesser loss of working and earning days. Surgery with laparoscope is more precise because it is magnified view. Further vision is much better because it's like having your eye behind the structure because you can see with the telescope at places where the surgeon's eye cannot reach.
Q4. If the cuts on the abdomen are so small in Laparoscopic surgery, how do you remove the uterus or a large tumour from inside the abdomen?
Quite often if the tumour is not malignant and contains fluid, it is punctured to collapse it into a smaller size. If it is solid, it can be cut into smaller pieces inside the abdomen using a special instrument. The collapsed or cut structures can be removed gently through the 1 cm cut on the abdomen which may be increased a bit if required. After hysterectomy, the uterus can be removed easily from below, through the vagina.
Q5. Will there be much pain or discomfort after Laparoscopic Surgery?
There may be some pain and discomfort in lower abdomen for one day to few days after Laparoscopic surgery but this is much less as compared to open surgery because the incisions on the abdomen are much smaller and there is much less tissue handling inside the abdomen by fine instruments instead of rough, big, gloved hands which can cause tissue injury in open surgery. There may be some pain in the shoulder following laparoscopy. This is not serious and is due to the gas used in the surgery to make space for instruments.
Q6. When can I be discharged from hospital?
Following Diagnostic Laparoscopy or with simple Operative Laparoscopy you can expect to be discharged from hospital latest by the morning after surgery. In most other cases of intermediate or even major surgery, discharge is generally 1-2 days following the surgery unless there is some health issues prior to the surgery or any complication during the surgery. The complication rates for Laparoscopic surgery are not more than for open surgery and depend upon patient factors like anaemia, diabetes, obesity and skill of the surgeon.
Q7. When can I perform routine household activities or return to work after Laparoscopic Surgery?
Recovery after surgery depends upon many factors: presence of health problems before surgery; why the surgery is required; what surgery is being done; problems or complications of surgery, anaesthesia or blood transfusions. If all is well, one can perform routine household activities by 1 week, provided one doesn't feel tired. Although there may not be any harm, it may be unwise to be normally active within 48 hours of procedure. Following Diagnostic Laparoscopy or Operative Laparoscopy for simple procedures, one can return to work in 1 week. For other procedures, a 2-3 week off from work is reasonable. It depends on the type of work you are returning to. Avoid too rapid return to work if it is manually hard or requires standing for long durations of time. Sometimes a surgical procedure brings on a well needed rest and break from a lifetime of work. Mostly, when you return to work depends upon your own body and its signals of tiredness. You need to listen to those signals.

Brain surgery involves several medical procedures, which incorporate fixing issues with the brain, including changes in the tissues of the brain, cerebrospinal fluid and brain blood flow. Brain surgery is quite a complicated method of surgery and the type of surgery to be conducted depends on the underlying conditions.
Reasons for Brain Surgery:
Brain surgery is performed for the correction of physical brain abnormalities. These abnormalities could occur because of diseases, birth defects and injuries. A brain surgery is required when the following conditions arise in the brain:
- Abnormal blood vessels
- Blood clots in the brain
- When the protective tissue or dura is damaged
- Due to nerve damage
- Parkinson's disease
- Any kind of pressure after an injury
- Skull fractures
- In case of stroke and tumors
A surgery may not be required for all the above mentioned conditions, but in case of many, a brain surgery is very important as the conditions may worsen health problems.
Types of brain surgeries:
- Craniotomy: During this open brain surgery, an incision is made in the scalp, and a hole is created in the skull, near the area, which is being treated. After this process is complete, the hole or bone flap is secured in its place using plates or wires.
- Biopsy: This form of brain surgery helps in the removal of a small amount of brain tissues or tumors. After removal, the tissues or tumors are examined under a microscope. The creation of a small incision and a hole in the skull is indicated as a part of this process.
- Minimally invasive endonasal endoscopic surgery: This form of brain surgery enables the removal or lesions and tumors via the nose and sinuses. Private parts of the brain can be accessed without creating an incision. An endoscope is utilized in the process which is used to examine tumors all across the brain.
- Minimally Invasive neuroendoscopy: This process is similar to the minimally invasive endonasal endoscopic surgery. This method also involves the use of an endoscope for removal of brain tumors. Small, dime sized holes may be made in the skull to access some brain parts.
Brain surgeries may be associated with several risks. They may be:
- Allergic reactions to anesthesia
- Blood clot formations
- Swelling of the brain
- A state of coma
- Impairment in speech, coordination and vision.
- Problems in memory
- Strokes and seizures
- Infections in the brain
A brain surgery is a serious and very complex surgery. There are different kinds of brain surgeries, which are conducted depending on the condition and severity of the disease.
