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?

Make Your Home Cancer Free

While cancer has become a common place disease, most of its causes remain unknown. Most of us are not aware that few regular everyday materials present in most households are potential causes of cancer. Lets know about them, the health hazards they can cause, and be aware.
Check this list.

1. Shower curtains - shower curtains are made of toxic chemicals which get into not only the shower or the bath but also into the environment. It emits harmful chemicals which are called voc (volatile organic chemicals) and can prove to be very harmful for us.

2. Deodorants - deodorants and antiperspirants are known to have various ingredients which have cancerous properties. These sprays stay on our bodies for hours, until we wash them off. While on our bodies, they chemicals harm our skin and even through it.

3. Strong shampoos - many shampoos contain toxic chemicals though there is no scientific proof that they cause cancer. However, the array of chemicals used to make shampoos is definitely harmful for us and best, if avoided.

4. Room fresheners - air-fresheners, like deodorants have vcos which are toxic and extremely harmful for us. They aggravate asthma and even affect reproductive development. They have hazardous components which can be cancerous. It is advisable to use essential oils.

5. Scented candles - scented candles mostly have wicks made of lead. While they serve a good purpose, there is no point in using something which gives momentary relief but can prove hazardous in the long run.

6. Certain paints - permanent markers, acrylic paints, solvents, etc contain hazardous chemicals which have been associated with occurrences of cancer, allergies and oral damages.

7. Gardening chemicals - household pesticides, herbicides or fungicides that we often use in gardens can contain carcinogenic materials which are believed to cause lymphomas and breast cancer (in animal models).

8. Plastic food/beverage containers - plastic materials containing bpa, or bisphenol a are believed to dangerous for health. So when one is using plastic bottle or food container make sure it is bpa free.

9. Nonstick cookware - cooking utensils which are made with a nonstick coating (teflon) is suspected to be a carcinogen. The main chemical in nonstick coatings is perfluorooctanoic acid (pfoa) is known to cause cancer. Glass, cast iron, copper, and ceramic or pfoa free nonstick cookwares are safe.

10. Last but not the least, in case of any lump or doubtful mass, consult an Oncologist without delay.

10 Concrete Ways To Minimize Cancer Risk

Brain tumours vary in shape and size and the same is the case with their symptoms. The location of the tumour affects the symptoms greatly. Just like in any other type of a malignant tumour, brain tumour has a rapid growth and proliferation of abnormal cells that may have its origin in affected site or areas adjacent to it. As per studies, every 2 in 1,00,000 people are said to be affected by brain tumour in India. However, it may come as a relief to some as not all brain tumors are cancerous or life threatening. Some are benign tumors and seldom pose any threat to the affected individual.

Types of Brain Tumor
Brain tumors may be primary or secondary.

Primary brain tumor: Here the abnormal mass of cells that originated in the brain do not metastasize to the other organs. Based on their location in the brain, the primary brain tumors may be of the following types.
Gliomas: One of the most common types of primary brain tumors, gliomas can have their origin in the spinal cord or the brain. Some of the common types of gliomas include Astrocytomas (originates in the cerebrum of the brain), Glioblastomas (these tumors form from the Astrocytes which form the supportive tissues of the brain), Ependymoma (these develop from the ependymal cells which are present within the CNS), Oligodendrogliomas (these tumors are found to arise from the oligodendrocytes).
Schwannomas: Also called as Acoustic neuromas, these primary brain tumors form on the nerves that play an important role in regulating the balance and hearing from the inner ear to the brain.
Meningiomas: These type of tumors are usually benign and have their origin in the meninges (membranes surrounding the spinal cord and the brain).
Primitive neuroectodermal tumors (PNETs): Primitive neuroectodermal tumors (PNETs) are rare malignant tumors that originate from the fetal (embryonic) cells in the brain.
Pituitary adenomas: As the name suggests, these tumors arise from the pituitary gland located at the base of the brain.
Medulloblastomas: Common among the children, these malignant primary tumors develop in the brain (lower back) and gradually spread via the spinal fluid.
Other types of primary brain tumors include Craniopharyngiomas and the Germ cell tumors.
Secondary brain tumors: Unlike the primary brain tumors, these tumors have their origin in the other body parts and organs (mostly in the lungs, skin, colon, breast, and kidney) and then gradually metastasize to the brain. The secondary brain tumors are found to be more common.
Symptoms or warning signs associated with brain tumors:
Some of the signs and symptoms that may be indicative of a brain tumor include

People with brain tumors often get seizures (due to the irritation caused by the tumors in the brain).
A headache (mild to severe depending on the part of the brain affected by the tumor).
A person experiences numbness or a tingling sensation in the legs and arms.
There may be difficulties in walking or balancing.
A person finds it difficult to concentrate.
There may be some problems with hearing, speech or even vision.
A person may experience weakness restricted to only one part of the body.
The symptoms may not necessarily indicate a brain tumor but it is always wise not to neglect the symptoms either.

Brain Tumor - What Are The Types?

If you are suffering from breast cancer, it is recommended that you undertake Ayurvedic measures for an effective and natural treatment. Breast cancer is a form of cancer that occurs in the cells of your breasts. The breast cells undergo abnormal growth and go out of control. This form of cancer is likely to occur in both women and men, although it is most common in women. A lot of breast cancer cases start from the ducts or lobes, while others start from the cellular lining of your milk ducts.

Ayurvedic view
According to the principles of Ayurveda, your body is based on the tridoshas, which include vata, pitta, and kapha.

An imbalance in these doshas can lead to diseases and disruption in your health. Cancer occurs when an imbalance of all the three doshas is experienced.
An improper diet and lifestyle account for being the primary reason for this imbalance in doshas, leading to breast cancer.
Your digestive fire is also affected, which leads to the accumulation of toxins, thereby blocking all the channels of your body.
All these factors are collectively responsible for the development of breast cancer.
Ayurvedic treatment

Breast Cancer - Can Ayurveda Help You Treat it?

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.
