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.

Brain Size - How It Is Related With Intelligence?

Surgery to remove abnormal growths of the brain, peripheral nervous system or the spine or any disorder can be tricky because the brain and the skull that shields it are complex areas. In the old days, open surgery was the only way to access the brain or spinal cord. But, with the invention of laparoscopy, keyhole surgery to treat neurological issues is gaining ground.

What is Neuroendoscopy? 
Neuroendoscopy is a surgical procedure that is favoured by doctors and patients alike because it is minimally invasive.
Before the surgery, you will be administered general anaesthesia so that you will be unconscious during the entire duration. During the surgery, the surgeon will drill a minute hole into your skull just above the eyebrows. You skull also has two natural openings. That is why the surgeon may make use of the nose or the mouth to access the region that needs to be operated upon.

Neuroendoscopy is useful because -

  It lets the surgeon reach regions that are not accessible with open surgery
  The tumour can be removed without any damage being done to surrounding tissues

An endoscope is a delicate device with a high-resolution camera mounted on it. There is an eyepiece on the other end. The device is also fitted with a light. When it is inserted into the brain, it lights up the passage and the eyepiece allows the surgeon to take a look inside. The camera sends a live feed of the path it is traversing and this guides the surgeon. When the tumour is reached, it is gently removed with other surgical instruments that too were inserted through the cavities or the drilled hole.

Benefits of Neuroscopy -
There are several advantages of relying on laparoscopy -

  The patient endures less pain
  Fewer chances of infection
  Faster recovery
  Very little scarring of tissues

Which Disorders call for Neuroendoscopy?
Any of the following disorders can be put to rights with a neuroendoscopic surgery -

  Pituitary tumours
  Rathke s cleft cysts
  Pineal area tumours
  Ventricular tumours
  Skull base tumours
  Brain inflammation triggered by an infection
  Chordomas
  Cerebrospinal fluid fistulas
  Trigeminal neuralgia
  Cerebral aneurysm

After Surgery-
Once you undergo the neuroendoscopic surgery, you will have to be rehabilitated so that your condition can be monitored round the clock. Neuroendoscopy is a state of the art clean and efficient surgery that is beneficial to both surgeons as well as the patients.

Antibiotics are something which have changed are lives for eternity as well as for the better, to say the very least. With each day that passes, there are greater strides of advancement which are made in the field. Of late, it is said that antibiotics also have the potential to stop new cells in the brain from growing, which is quite a risk when it comes to their usage among people are sick.

Research has found that if the brain of the person under treatment is subject to sustained use of antibiotics, it is true that the brain can lose its functionality for a quicker time than what one would consider to be normal. So it can be said, this usually is not the advisable way to go.

Like most testing practices when it comes to medication, antibiotics which were tested on the brains of the subjects i.e. those of mice had an effect of mitigating their high-level memory. How this happened to be is rather interesting, to say the very least.

How dangerous can antibiotics be?
It is often said that eating right does wonder for a person s brain. Well, the mice that were not treated with the antibiotics were seen to lose the healthy bacteria present in their stomachs. In addition to this, they lost new brain cells. This led on to them performing worse in mental tests than their peers who had had some antibiotics administered to them on a consistent basis.

Now a cynic may point out that what is seen to be true for mice may really not hold true when it comes to humans being considered. However, if it is taken into due account that a lot of path-breaking research is carried out on mice, there is quite some credence to the results of the study.

To supplement the evidence even further, it was also seen that for mice which were in possession of low levels of monocytes, which are a type of white blood cells. It was seen that there was a great dependency on monocytes for the generation of white blood cells. The part of the brain which is hindered by generating new cells on account of the sustained use of antibiotics is the hippocampus.

Antibiotics are the proverbial shot in the arm which can aid recovery by destroying the threat to a person s wellness. However, it is to be considered that they are not safe in general as there is collateral damage!

Antibiotics - Can They Stop The Growth Of Brain Cells?

Whether it's a child or a grown-up, difficulty in concentrating is often experienced by many people. While, people tend to brush off this particular problem to be nothing worth being concerned about, but sometimes, there may be a more serious underlying issue for which concentration problem is only a mere symptom. Yes, difficulty in concentrating can be a sign of a neurological disorder. Keep on reading to know more about neurological disorder, its symptoms, and treatment.

Reasons behind difficulty in concentrating
Inability to focus properly is a periodic and normal occurrence for many. While sometimes it is the emotional stress or physical tiredness that is responsible for it, at times it is the outcome of hormonal changes in the body, such as during pregnancy or menopause that causes it. However, when experienced in severe degrees, it may be a characteristic of a serious psychological condition called neurological disorder. Affecting both adults and the children, the neurological disorder can be a serious threat if not treated at the right time.

Neurological disorder
Neurological disorder refers to any condition that happens due to the dysfunction of the nervous system or the parts of the brain. Depending on the location of the damage to the nerve or in the spinal column or the brain, different areas controlling the vision, movement, thinking or hearing can be severely affected. The decreased ability to focus on something or loss of concentration power being one of the many symptoms of neurological disorders among the various complications it causes.

Causes behind neurological disorder
Many reasons lead to neurological disorder or its associated symptoms like difficulty in focusing. From lifestyle-related issues to nutrition related causes, physical injuries to some infections, complications during childbirth, and genetics to environmental influences, numerous factors can be responsible for such disorder. Depending on the type of neurological disorder, the symptoms can vary from to another, while for some difficulty concentrating can be a symptom, for some, the symptoms can be more of physical difficulties such as problems in walking or difficulty speaking or seeing, etc.

Dealing with difficulty concentrating
Once the cause of the neurological disorder is determined, there are various treatment options, offered by the doctors. To deal with the neurological disorder as the cause of difficulty concentrating one may need medications and treatment provided by the medical professionals. However, there are a few tips that one can keep in mind, such as minimizing multitasking and focusing on one single thing or thought at one time or dividing tasks into small steps, etc.

Difficulty in concentrating means the ability to focus on thoughts or action decreasing. In case one experience this issue on a long term basis or excessively, visiting the neurologist as soon as possible should be the best thing to do.

Problem In Concentrating Could Be A Sign Of Neurological Disorder!

Neurological disorders may creep in due to many reasons. It may be due to degenerative diseases, accidents, other health conditions, birth defects or genetics. The most common form of disorder occurs due to non-functional brain cells in some parts, and loss of myelin sheath in neurons, which protects the nerve signals in their complete transfer from origin to destination. These losses are irreparable, but further degeneration can be avoided with Ayurveda. Panchakarma, the branch of Ayurveda, which deals with detoxification of the body and mind, specially helps. Over a period of time, it can bring back the lost sensation in nerves. Yoga, pranayama and Ayurvedic treatments lead to recovery and relief to a huge extent.

Important facts about Panchakarma
There are 3 important steps in Panchakarma, which are followed one after another to get the result. The main objective of Panchakarma is to detoxify the body. Virechanam, vamanam, sneha vasti, nasyam and kashaya vasti are the 5 folds in Panchakarma.

Poorvakarma or preparing the body, followed by Abhyangam or massage, followed by Elakizhi or herbal paste massage, and finally podikizhi, or steam bathing makes the body ready for receiving further treatments.
Njavara Kizhi is the special treatment done in Panchakarma where the body is given a rice bolus massage to improve the joint and neuro functions.
What is Njavara Kizhi?
Njavara is a variety of rice, which is specially used for Ayurvedic treatment and massages. In this treatment the rice is made into a pudding by boiling it with milk. This pudding is then made into boluses. The boluses are filled in muslin cloth, and then using these muslin bolus dabs, the whole body of the patient is massaged. This full-body massage has excellent effects on neurological and joint functions. The deep tissues within the body are rejuvenated. The treatment is carried on for 45 minutes to 60 minutes by therapists or experts. Another form of the treatment requires the rice to be made into a paste, and then the paste is applied all over the body. But this is more preferred for beautification.

Other effective therapies
Siro Vasti, Kati Vasti, Ela Kizhi and Nasyam are all different forms of Panchakarma treatment, which detoxify the body and mind and rejuvenate the body and nerve functions. But these treatments cannot be conducted on the body on your own. You need a masseur who must be a specialist in Ayurveda to do this for you. Hence contacting Ayurvedic clinics, doctors or experts would be the best to start the treatment.

Neurological Disorder - How Panchkarma Therapies Can Help?

Obesity is the new-age lifestyle disease with multiple ramifications. While its effects on the physical aspects are very evident, the damage it does to the brain are more severe, though not obvious. Read on to know some harmful effects of obesity on the emotional well-being.

Leads to binge eating: There is a certain pleasure in eating sugary and fatty food, and this is lost with depression. Therefore, to get that emotional satisfaction, people tend to eat more chocolates, cookies, milkshakes, and other weight-accumulating food items, which further add to obesity. Greater the weight gained by a person, lesser the response or happiness from such food products.
Increases impulsivity: The area of the brain known as orbitofrontal cortex, which is in charge of controlling impulsivity, shrinks in obese people. This results in people eating more impulsively.
Affects immunity: Obesity is a major cause of inflammation, leading to damage in certain parts of the brain. This impairs the immune system, making the affected person more prone to infections and tissue damage. This leads to increased chances of diabetes, heart disease, stroke, sleeping disorders, eating disorders, etc. The chemical known as C-reactive protein increases as seen on MRIs in obese people, and which is usually seen in patients with chronically increased inflammation.
Effects on memory: As the BMI increases, there is a decrease in scores of memory tests. This effect is more obvious in women after menopause. With increased fat accumulation, more hormones are released, which affects the memory. Increased inflammation also affects cognition and memory.
Increased risk of dementia: With more belly fat accumulating, there is extra stress on the body to burn the visceral fat. This reduces brain size and causes certain hormones to release, which further affects the body s ability to remember things. It has been proven that people with smaller brain size are at greater risk for developing dementia.
Weight loss stress adding to more stress: When obesity sets in and the BMI goes up, there is an added pressure to lose weight, which further ups the stress levels. During these dieting days, the brain is constantly alert and finds ways to eat more. This also leads to excess eating. Moreover, there are indications that there could be genetic changes during this phase, which may leave a permanent mark in the person s composition.
Depression: When a person is not happy with their reflection in the mirror, the chances of feeling good and happy are very less. In this age, where aesthetics plays a major morale booster, an obese image staring back does not help at all.
So, if you have a risk of obesity, watch out. It is not just how you look, but how you feel is also altered.
