The relationship between intelligence and brain size, both among people and between various species, has never been precisely well defined. People often believe that their outstanding psychological capacities must mean that they are superior to all animals as far as brain size is concerned. However, it is not true since whales and elephants have much bigger brains than humans and humans have the same brain-to-body mass proportion as mice do.

Here are a number of ways by which the brain size can be determined:

Encephalization remainder: Since it would be against human instinct to admit loss and defeat, researchers have created a measure to determine the brain size called the encephalization remainder. It is the proportion of actual brain mass with respect to the anticipated cerebrum mass for the animal s size (based on the suspicion that bigger animals require somewhat less brain matter with respect to their size, compared to little animals). By this metric, human beings prove to be the best, with an EQ of 7.5 outperforming the dolphin's 5.3 and the mouse's 0.5.
IQ testing: Without a solitary and evident method for measuring intelligence, some improved tests like IQ (Intelligence Quotient) are by and large acknowledged as a moderately decent working device. IQ estimations are not without issues, and there is a great deal of criticism about their significance. IQ testing uses government sanctioned tests, for example, the WAIS III (Wechsler Adult Intelligence Scale). The normal IQ is somewhere around 90 and 110. The scores beneath the normal may demonstrate changing degrees of pathology, for example, marginal intellectual function, or mental hindrance of different severity. Over the normal range is regularly connected with knowledge, splendour, talent, or genius. However, as with computers of a few eras, size and intellect do not precisely relate. Present day portable computers weighing around one or two kilogrammes can store more data and perform a greater number of assignments than supercomputers from the 1980s that used to possess expansive structures. This is a contrast amongst quantity and quality. Numerous scientists now hold the view that it is not the whole brain, which is bigger in a human with a higher IQ, yet rather certain zones that are denser and might be bigger. A fascinating late revelation is that these ranges can be expanded in size and enhanced in usefulness during the course of our life.
NeuroplasticityIt refers to the dynamic procedure of repair and maintenance that our brains are continually experiencing. We are conceived with around hundred billion neurones, yet lose around two hundred thousand a day to a procedure called pruning. As we develop and grow, pathways in the brain that are not required are detached, and the neurones pass on. However, in a compensatory procedure, new neurones are delivered and more detailed associations are built up between neurones that are more dynamic. This is the procedure of de-cluttering, in which our brains develop to work at most extreme effectiveness. If you wish to discuss about any specific problem, you can consult a Neurologist.

Acoustic neuroma is a benign tumor that occurs in the primary nerve between the brain and the ear. The tumor progresses very slowly and can influence your balance and hearing. In certain cases, if the tumor becomes very large, then it may also impair vital functions of the body.
Symptoms-
The symptoms of acoustic neuroma tend to develop when the tumor starts to press on the nerve and its adjoining branches. The symptoms of this disorder are  
You may experience hearing loss on one side which might worsen gradually.
You may have problems in balancing yourself.
A continuous ringing sound in the ears.
Persistent dizziness.
If the tumor is large and presses on the nearby nerves, then you may experience numbness of the facial muscles.
In some cases, it may impair the vital functions of the body.
This disorder is caused by a malfunctioning gene. There is no documented reason as to why the gene malfunctions.
The treatment options for this disorder are  
Constant Monitoring: These tumors tend to grow very slowly but might spurt in some cases. In order to prevent damage to your body, they need to be monitored on a regular basis. Imaging tests are recommended on a periodic basis to determine the growth of the tumor.
Radiosurgery: Stereotactic radiosurgery is done to treat acoustic neuroma that is small in size. In this surgery, radiation is directed at the tumor without creating any incision. It is done to limit the growth of the tumor and preserve your hearing.
Surgery: The tumor can be removed by using surgical procedures. It involves administering general anesthesia, followed by removing the tumor through an incision on the skull or the inner ear. Surgery is used to remove the tumor and preserve your hearing abilities. 

Acoustic Neuroma - Everything You Need to Know

Lasers have come as a boon to treat many medical conditions very safely and effectively. They are absolutely indispensable for permanent hair removal, tattoo removal, freckle removal, skin rejuvenation, treatment of birthmarks and many other internal medical conditions. There is a common misconception that lasers are harmful for your skin and can cause skin cancers. This is far from the truth, since lasers are actually used to treat skin cancers and also help in keeping the skin youthful and rejuvenated. 

Lasers use non-ionising light (like red or green light) and not ionising radiation like x-rays or gamma rays. These spectrums of light do not induce cancer formation. 
Fair skinned races are at much greater risk than skin of color. Melanin in darker skin does not allow harmful UV light in sunlight to penetrate through and the risk of skin cancers in darker skin is therefore small with normal sun exposure. Also, common lasers do not use UV light. 
Laser treatments are administered not in prolonged durations but in pulses much less than a second and parameters in the range of milliseconds and microseconds are most commonly used. Prolonged sun exposure is the most common precipitating factor for skin cancers. 
Laser light does not reach any internal organ. In fact, it requires some expertise even to make laser light reach its target just 1-2 millimeters below the skin. This is because melanin pigment in skin blocks laser light from getting through. An expert dermatologist with sound knowledge of skin optics and laser physics is able to achieve this safely and effectively. 
Laser treatments work on the principle of ''selective photothermolysis'. This means that laser light very specifically destroys only the intended target. Thus, a hair removal laser will destroy only the hair roots while leaving surrounding skin structures unharmed. Similarly, blood vessels in birth marks, collagen in wrinkles or scars, abnormal growths and cancers and individual inks in tattoos can be targeted very specifically with lasers without affecting any other structure.

Lasers - Do Not Cause Cancers!

Leading a life with peripheral neuropathy is quite similar to riding a roller coaster. Managing the pain can be frustrating at one time and overwhelming on the other as patients can experience alternating symptoms with debilitating pain. So you should learn about the various treatment options as they can help you go a long way in managing the pain.

The peripheral nerves are considered the longest in the body which extend from the hands to feet. When these nerves are damaged, you may feel some sort of pain, tingling in the hands and feet and even numbness, and these symptoms can even get worse and you may experience stabbing pain with increasing weakness. 

There are many things that you should know about peripheral neuropathy as they would help you to manage the condition much more effectively.

Diabetes is the leading cause of neuropathy: More than 70% of diabetics develop symptoms of peripheral neuropathy. So you should keep your blood sugar within optimum levels as a means of reversing diabetic neuropathy.
A melange of causes behind neuropathy: Though diabetes is the number 1 cause of peripheral neuropathy, other causes include deficiency of vitamin B12, alcoholism, traumatic injury, chemotherapy and exposure to toxic substances. Physicians may find it difficult to pin-point the cause and when this happens. This is often termed as  idiopathic neuropathy .
Medications causing neuropathy: If you are suffering from diabetes and being treated with the drug named metformin, you may develop peripheral neuropathy.
Preventing neuropathy is the most recommended way: While it is the fact that some nerves may potentially get damaged from certain surgeries or injury, peripheral neuropathy can be potentially prevented or sometimes stopped from spreading. As diabetes is a major cause of diabetes, being watchful about your diet and exercising regularly can help you go a long way to prevent diabetes as well as neuropathy.
Pain is not simply confined to a tingling sensation: Though pain and a tingling sensation is the commonest and easiest way of recognising the symptoms of peripheral neuropathy, each of your sensory, motor and autonomic nerves can show different set of symptoms that you should be watchful of.
A diet may make the symptoms even worse: You can either help or hurt your nerves with your choice of foods. For improving symptoms, you should avoid food with excessive sugar, refined grains and artificial sweeteners as they may strain your nerves and irritate them further.
Whether you are recently diagnosed with peripheral neuropathy or living with it for many years, understanding a few conditions would help you make informed decisions about your well-being.
