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.

Although surgery is considered to be the first step of treatment in any form of tumor but its feasibility depends upon the type, size and location of the tumor. It is not necessary that every kind of brain tumor might require surgery.
Indications of Brain Tumor Surgery
- Diagnosis of the type of tumor by taking a sample of the tumor for laboratory examination
- Complete resection of tumor
- Removal of the tumor as much as possible to slow down its growth and improve the symptoms.
- Remove the tumor in order to help other treatment
- Provide direct access for other forms of treatment like chemotherapy, radiotherapy etc.
- To relieve pressure caused by tumor on surrounding structures
Types of Brain Tumor Surgery
The different types of surgery that are performed in cases of brain tumor include the following:
Craniotomy: Craniotomy is the most commonly performed procedure to remove brain tumor along with a piece of bone. The removed bone is replaced and the tumor is sent for histopathology (biopsy). The surgery is performed using a high end microscope by any of the following techniques:
- Extended bifrontal craniotomy
- "Eyebrow" craniotomy (supra-orbital craniotomy)
- "Keyhole" craniotomy (retro-sigmoid craniotomy)
- Orbitozygomatic craniotomy
- Translabyrinthine craniotomy
Shunt: A narrow piece of flexible tube with a pressure regulated valve in between is called a shunt. This is used to relieve the intracranial pressure caused by obstruction of the natural brain fluid (CSF) pathway by tumor mass. The procedure involves insertion of a drainage system into the brain to remove or drain excess of blocked fluid into the peritoneal cavity.
Stereotactic surgery: This surgery is done by creating a three-dimensional image called stereotaxy using computers. It aims to find out the location and position of the tumor. In fact it can also be done to aid tumor removal, implant radiation pellets or for other treatments.
Embolization: It is a procedure used to reduce the amount of blood supply to a tumor by blocking the blood flow in the selected arteries. It is generally performed before the main surgery.
Endoscopy and endoscope assisted surgery: Endoscope is the tool which helps to closely visualize the tissue through small openings in difficult to reach areas. This tool can be used in various brain surgeries to precisely reach the target location without damaging the adjacent structures.
Adjuvant modalities to improve outcome: In addition to above mentioned surgeries, following surgeries may also be performed in relation to brain tumor treatment:
