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.

How Physiotherapy Can Help with Neurological Disorders

Neurological disorders are problems with any one or a combination of the central nervous system or any of its peripheral systems such as cranial nerves, neuromuscular junctions, and the autonomic nervous systems among others.

Some extreme examples of neurological disorders are:

- Dementia
- Alzheimer's disease
- Parkinson's disease
- Epilepsy
- Disorders brought on by strokes
- Multiple sclerosis and others

What is physiotherapy and how can it help?

Physiotherapy is a form of treatment where practitioners use physical forms of treatment such as massages, exercises, heat treatment and other controlled forms of external stimuli to treat physical disorders.

This method of treatment can be very effective in correcting neurological disorders.

Some of the physiotherapy techniques, which can be implemented to help patients, are as follows:

Electrical Stimulation: This method is commonly used to treat muscular problems, especially incurred after an accident or any other form of injury. In this method, controlled electric stimulation is given to specific nerve areas over the skin to stimulate them.

Heat treatment: This method involves applying heat to parts of the body such as joints or muscles where there is nerve or muscular damage. This treatment is especially effective for muscle related problems.

Ice or cold treatment: Vertically opposite to the principle of heat treatment, ice or cold treatment is used to contract muscles within the body. This is especially effective where inflammation needs to be controlled.

Manual therapy: Possibly the most common form of physiotherapy, this method employs massages, pressure points, stretching and hands on strengthening exercises and helps regularize nerve impulses to areas where they have been affected.



How Physiotherapy Can Help with Neurological Disorders

Study of the brain has fascinated specialists all over the globe since time immemorial. The brain being the most vital organ for survival and coordination is perhaps the most complex of them all too. This has led to a limited understanding of its working in spite of the available advanced technology. However, with the advent of techniques for diagnosis and treatment, therapeutic strategies are evolving. This is a major step towards rendering Neurosurgery safer than ever in the history of mankind.

Neurosurgery through the 20th Century-

During the beginning of the 20th century, Neurosurgery was considered as a specialty. The clinical-neurologist would draw conclusions related to lesions in the brain through neurological examination and clinical history. It enabled diagnosis of vascular lesions, spinal disorders, and brain tumors. During the second and third decades of the 20th century, vascular pathologies and brain tumors could be diagnosed indirectly through techniques like angiography, ventriculography, and pneumoencephalography. But since the operative techniques were too crude and the lack of skilled professionals were rampant, there were high rates of morbidity and mortality due to neurological conditions. Generally, after diagnosing the nature of brain lesion and its site, surgery was performed with inadequate maintenance and control of intracranial pressure and through not too sophisticated surgical instruments.

During the fifth and sixth decades of the 20th century, chemotherapy and radiation treatment came into the picture for treating malignant brain tumors, thereby reducing mortality to a good extent.

During the seventh decade of the 20th century, Computed Tomography (CT) scan provided a better understanding of the location of lesions in the brain which slightly substantiated the earlier techniques. Then, the procedures for cerebrospinal fluid diversion significantly improved management of intracranial pressure during surgery.

It was only during the last decade of the 20th century that the Neurology saw a giant progressive leap through the introduction of Magnetic Resonance Imaging (MRI) and powerful high magnification microscopes. Combined with Neuroanesthesia and Intracranial Pressure Management, this aided surgeons to work on a relaxed brain. This promoted safe removal of the brain tumor and better management of vascular lesions. Moreover, the understanding of micro-surgical anatomy improved drastically, leading to a boost in confidence levels of the micro-neurosurgeons performing the operation.

Neurosurgery in the 21st Century-

The 21st century is actually a revolutionary era that uses powerful computers in almost all the fields possible. Computer-based applications such as Neuro-imaging, Neuronavigation, Intra-operative Neuro-monitoring, and Neuro-modulation are now used in standard neurosurgical practice as a part of the routine. Extremely powerful CT scans and MRIs are used for diagnosis before surgery. The advent of nanotechnology and its application in Neurosurgery is doing great and has a promising future ahead based on the current study of scenarios. Moreover, there is a possibility of most of the Neurosurgical procedures becoming minimally invasive. Frameless Stereotaxy is another technique that helps in locating the exact position of the tumor, which further helps the neurosurgeon in navigating with great precision the very sensitive, high-risk areas of the brain. Such techniques, to a great extent, have lowered mortality and morbidity, lessened the rate of recovery, and chances of infection related to Neurosurgery.

Take Away-

A number of techniques for diagnosis and precise location of the tumor in the brain have made Neurosurgery much safer today, due to advancement in science and technology, than it ever had been in the history of mankind.

Advancements In Neurosurgery - Know How Safe It Is!

Your mother has often yelled at you for playing video games for long hours, but obviously you haven t paid heed to it. Such is the obsession with video games that they don t let you rest unless you have championed all the levels in the virtual interface. Here is the source of all problems. Studies have revealed that video games have a direct relation to neuropsychiatric problems. As a result, many health experts across the world consider video game as a kind of health abuse.

People who play action-oriented video games are at higher risks. The more you indulge in these kinds of games, the more they are going to affect the hippocampus section of your brain. It is that part of the brain which is considered to be the centre of your nervous system, memory and emotion. Reduced hippocampus volume may make person vulnerable to multiple neuropsychiatric complications. Let us see some of the signs, which may indicate the onset of certain complications arising from an over indulgence in these games.

1. You spend hours on the computer or related gaming devices and devote lesser hours for your family and friends

2. You get agitated when someone stops you midway through the game

3. You become socially isolated and show signs of occasional mood swings

4. You are unable to keep a track of time once you start playing

5. You repeatedly neglect your studies, resulting in a dip in performance at school

Why does this happen?

All of the above signs indicate that sooner or later you might develop neurological problems. When you spend an excessive number of hours on playing and navigating through the games, the  hippocampus  portion of your brain shows signs of decreased gray matter. As a result, the volume of the hippocampus shrinks, causing severe nerve related disorders such as schizophrenia, Alzheimer s disease, dementia, depression, and overall general stress.

One of the biggest reasons behind this is a lack of self-control. Most of the video games will encourage you to steal cars, run away after a theft and kill your enemies. Moreover, if you succeed, you are rewarded. This naturally unleashes a blatant urge for the gratification of all these awkward desires in your real life too. Hence, once you are encountered with the reality, you tend to show violent behavior.

Can Playing Video Games Cause Neurological Problems?

The neurones in the brain are constantly reorganising their connections both functionally and physically according to the environment, your thinking and behaviour. This ability is known as neuroplasticity. Through neuroplasticity the nerve cells of brain can compensate for injury to some parts of the brain and enable a person to recover from stroke, birth abnormalities. It is also beneficial in treating autism, ADD, learning disabilities and helps manage obsessive compulsive disorders.

Here are seven things you should know about neuroplasticity.

Change depends on the attentiveness of the brain: Neuroplasticity changes can only happen if the brain is alert and active. When the brain is active it releases neurochemicals that are necessary for the neurone connections to change. If a person is distracted to inattentive, these changes cannot happen.
The more the effort; the bigger the change: Neuroplasticity changes depend on how motivated the person is to change or learn new tasks. For this reason, when it comes to using neuroplasticity for physiotherapy, it is essential to first deal with any depression or anxiety issues the patient might be having before attempting to rehabilitate them.
It helps strengthen neural connections: Repetition of actions is one of the key elements of neuroplasticity in physiotherapy. Through this, the strength of neurone connections is strengthened to include sensory information, movement and cognitive patterns.
It improves cell to cell connections: This is crucial to a patient s rehabilitation as it increases reliability and makes a person more independent. In turn, this makes behaviour patterns more reliable.
It helps predict actions: A task can usually be broken down into a series of smaller tasks. For example, feeding oneself can be broken down into steps that begin with lifting a spoon and filling it with food to finally putting the spoon into your mouth. Hence, along with completing an action, the brain must also know what to do next. Neuroplasticity helps improve this associative flow and allows the brain to predict the next step.
Changes can be temporary or permanent: Initial changes due to neuroplasticity are temporary ad only if the brain determines the experience to be desired is this change made permanent. This is why when treating mobility issues, patients are not always able to repeat tasks in the same way.
Memory guides the learning: When making new neural connections through neuroplasticity, the brain is taught to discard unsuccessful attempts and only remember the experience of the successful attempts. From here, adjustments are made to improve the connection.

Neuroplasticity - 7 Things You Must Know About it!

Polio is a virus that has the potential to infect any parts of the body including, but not limited to nerves and muscles. Primarily there are 3 types of polio namely, non-paralytic, spinal paralytic and bulbar. This disease shows minimal to no symptoms in more than 90 percent of the cases. 5 percent of the cases can show symptoms such as nausea, diarrhea, vomiting, sore throat and abdominal pain. Polio is a communicable disease and can cause massive damage if a proper dosage is not taken. It can spread through air, physical contact with an infected person, coughs etc.

Polio can cause paralysis: Polio has a far-reaching permanent effect on the body. It can cause paralysis on any of the limbs leading to permanent disability. This severely alters a child s life. The far-reaching consequences of the virus can only be negated through vaccination.
Weak muscle: Polio can result in weak muscles, respiratory problems and loss of reflex. If the breathing muscle collapses, it can result in the death of a person. Any of the above-mentioned symptoms can lead to weak body development altering the fate of a child.
It can spread fast and quick: Polio spreads very fast through the air, physical contact, saliva and water. It not only affects a single life but put millions at risk of the disease. A 1916 outbreak of the disease killed 6000 people in the United States and left several thousands of people disabled.
It reduces the risk of infection: 3 dosages Polio vaccination under the age of 6 can save a baby from getting polio in future. The body successfully creates polio antibodies from the vaccines and gets enough ammunition to fight it if the virus attacks it in future.
Social responsibility: Massive amount of awareness campaigns have been run by countries all over the world to permanently eradicate polio from the face of the earth. As per the latest reports, only 3 countries are reported to have babies affected with polio; Afghanistan, Pakistan and Congo. It is, therefore, a social responsibility to take part in the mission of removing polio from the face of the earth once and for all.
Save future generation: Although polio is not known to be a disease which passes through heredity, there still lies a chance for the future generation to get this disease. In order to negate that from happening, it makes sense to get the vaccines on time.
Give your kid a head start: Every kid deserves to have an equal amount of privileges like others. One small mistake on part of the parents can heavily cost a child s future. In order to make sure your kids grow up with any apprehension of polio, it is very important to treat them with polio vaccines.
