Neurology .- The left brain is associated with logic, reason and scientific thought of a person, where information processing to transform it into words becomes the specialty of this “logical hemisphere.” There are several left-brain functions, including control of mathematics, logic, speech, writing, numbering … Common sense rules in people with dominance of this hemisphere.
What is responsible for the left hemisphere of the human brain?

The left brain, by analysis and logic-is responsible for processing the information to transform it into words. His specialty is to produce and understand speech sounds.

This part of the brain is related to the verbal, there are two structures associated with the development of language ability:

Broca’s area. This area deals with the speech, its analysis and understanding of language.
Wernicke’s area. Another important area related to language and is connected to Broca’s area through a bundle of nerve fibers.

As early as 1878 John Hughlings Jackson, British neurologist described the left hemisphere as “the center of the faculty of speech.”

Functions of the left hemisphere

While the right hemisphere of the brain is related to non-verbal expression, is more emotional, sensitive, intuitive and coordinates the left side of the body, the left uses the analysis, mathematics, logic, reasoning, and controls the coordination of right side of the human body. The functions of the left hemisphere human brain based on control:

Spoken language (spoken language).
The written language.
Scientific thinking (scientific skills).
The reasoning (logical reasoning).
The ability to learn.
The deduction.
The numeracy.
The logic grammar.

One can say that the two hemispheres of the brain , the left is analytical and sequential ie the “brain drain” or “logical hemisphere.”
How are the people who use more than the left hemisphere?

In right-handed people the left hemisphere is dominant and they use more dialectic and common sense.

Use the logical process and tend to reason everything point by point.
Before making a decision or, predominantly people of this hemisphere are well informed about it. Sometimes fail to know what they want for reasons too.
They are intellectual people , analytical and very detailed.
Understand everything based on logical principles.

It is the logical hemisphere and understands that thinks in words and numbers. He is in charge of seeking an explanation.

“It’s very preliminary. The study is not reason to change the consumption of coffee or tea,” said lead author Dominique Michaud, of Brown University’s Imperial College, London. And if both drinks had any direct effect on the risk of developing gliomas, would be small, and that brain tumors are rare.

In Europe, for example, annual fees are between 4 and 6 cases per 100,000 women and 6 and 8 cases per 100,000 men. The possibility of having a malignant brain tumor in life is less than 1 percent. Michaud said that if a higher consumption of coffee and tea protects some form of glioma, that would give scientists information about the causes of brain tumors.

The findings, published in American Journal of Clinical Nutrition, arising from an ongoing study in 10 European countries on potential risk factors for cancer. At baseline, 521,488 men and women between 25 and 70 years responded to questionnaires about their medical history, diet, exercise, smoking and other lifestyle factors.

Michaud’s team focused on more than 410,000 participants without cancer at baseline and with complete dietary information. During 8.5 years, only 343 were diagnosed with glioma and other 245, another generally benign brain tumor called meningioma. After dividing the participants into four and five groups, according to the consumption of coffee and tea at the beginning of the study, the researchers found no evidence of a dose-response relationship.

But the results changed when the researchers looked at two groups: those who consumed at least half a cup (150 ml) and those who drank less or nothing for both infusions. The more coffee / tea consumed were a third less likely to develop glioma, even after considering factors such as age and smoking. There was no association with the risk of developing meningioma.
According to Michaud, is not known why there is no evidence of a dose-response relationship between consumption of coffee / tea and risk of glioma. May be associated with difficulties in the accurate measurement of consumption of these beverages to the participants.

It is biologically plausible that coffee and tea influence the risk of developing glioma. For example, a recent experiment in the laboratory delayed the growth of a type of glioma called glioblastoma. In addition, coffee and tea contain antioxidants that protect body cells from damage that can cause cancer and other diseases.

Anyway, it is possible for coffee lovers and tea have other characteristics that might affect the possibility of developing glioma. These characteristics are unknown, as well as the causes of most brain tumors.

There are about 600 diseases that affect the brain. And it is striking that those who are more dangerous to our brain that tell us more. Parkinson, for example, takes 18,000 lives each year. This disease has taught us how the brain controls our body.

Knowledge of the mechanisms of memory are clear in Alzheimer’s disease. And by stroke researchers learned to keep isolated the damaged brain cells. In the most serious diseases are the best opportunities for science.

To stop the tremors caused by Parkinson’s began to inject genes directly into the brain might work in a better way than drugs.
The saliva of bats, meanwhile, has a powerful and safe compound that serves to break up blood clots that cause stroke.

During the course of 2007 the scientists first used brain stimulation in electric shock therapy in the form of paradise implant to a patient to wake up after five years of vegetative state.

But unfortunately it is also true is that for now only get relieve symptoms. These diseases continue to baffle scientists and medical researchers. No one could be cured so far. So the purpose of both the brain work is to discover the root cause of disease.

Tension Headache

Among the various types of headaches, those caused by stress are the most common. These are due to the cervical spine loses its normal curvature, which can be caused by a combination of factors: bad posture (at work, sleep), falls, strokes, accidents, whiplash-type injuries, stress, stress, etc.

To compensate for this straightening of the cervical spine and keep the head in a normal position, the neck muscles are overworked, reaching into spasm and create strong contractions.

Moreover, these problems can cause cervical, long-term spinal wear, such as cervical osteoarthritis. So it is very important not to mask the discomfort with pills, but treating the cause of the problem.

Migraines

Another frequent headache and migraine is more painful. The throbbing pain, usually located on one side of the head, often aggravated by light and is accompanied by nausea and vomiting.

Migraine occurs as a result of constriction of blood vessels in the head, with subsequent expansion of these resulting in pain. Although there is a hereditary predisposition field, migraines are not normal and must be treated properly.

In people with migraine, we often find spinal disorder affecting the nervous system that controls blood vessel function. To detect and to treat you, we recommend conducting a review chiropractic spine.

Chiropractic Solution

Chiropractic is not just the symptoms of the problem but also the root of it. This therapy offers an effective alternative, natural and safe treatment of headache.

For headaches caused by tension, Chiropractors work with the spine to restore cervical curvature and normal range of motion. That allows the muscles to relax, ending the painful spasms.

Relieve migraines by correcting spinal malfunction that affects the nervous system that controls the dilation and constriction of blood vessels in the head.

Remember that it is normal to have headaches. Ask your Doctor of Chiropractic so that you can take care or refer you to the appropriate specialist.

One study suggests that it is possible to identify the specific memory that a person is recovering from last episode, only on the pattern of brain activity. The results of work carried out by University College London, UK, published in the online edition of the journal Current Biology.

Explains Eleanor Maguire, head of the study, “we have observed brain activity in search of a specific episodic memory, and examine the trace of real memory. We found that our memories are represented permanently in the hippocampus. Now we’ve seen where they are we have a chance to understand how memories are stored and how they might change over time. “

The results are a continuation of an earlier discovery of the scientific team, which showed that one could identify where he was a person inside a virtual reality room in the same way.

The researchers showed ten people one of three very short films before a brain scan. Each film was played by a different actress and a daily scenario quite similar. For example, in one of the shorter a woman looking in her purse to find an envelope in a mailbox and threw in another one of them a different actress ended her coffee cup and threw in a trash empty.

The scientists scanned the brains of participants using functional magnetic resonance imaging (fMRI) while calling on those who remember the movie, and then included the image data in a computer log designed to identify patterns of brain activity, memories associated with every film.

Finally, the authors showed that these patterns could be identified in separate fMRI data to predict exactly what movie I was thinking about a particular person when he passed through the scanner.

The results imply that the neural traces of episodic memories are stable and therefore predictable, even after many reactivations. Although the patterns in the brain vary from one individual to another, the scientists also showed remarkable similarities to parts of the hippocampus that were active.

From the demo that you can access directly to information on individual episodic memories in the human hippocampus in vivo and noninvasively, the researchers conclude that the method offers new possibilities to examine the characteristics of episodic memory , to explore possible functional topographies and examine neural processing within the hippocampal subfields

Examples of images used in the study. (Photo: Archives of General Psychiatry) Know exactly what happens in the minds of those who suffer the condition is vital to help them move forward and leave behind the anxiety generated by their appearance. Many are unable to lead a normal, half requiring hospitalization at some point in their lives and about 25% attempt suicide.

Research published in the latest issue of Archives of General Psychiatry compared the brain areas were activated in 17 affected and 16 other healthy while viewing a photograph of themselves and another for a famous actor.

To tune a bit more on analysis of visual processing, scientists, University of California (United States) – Digital images were shown in three different resolutions: standard, in a format that highlights the details (spots, profile of the nose and eyes, hair) or a configuration in which only perceived the spatial relationship between different parts of the face and shape of it.

The medical imaging technique used was the fMRI, which allows observing in real time what brain areas are activated by performing a particular activity.

When individuals with body dimorphic disorder looked at his face, there was a hyper activation of brain structures related to the specific visual processing. This does not happen if they looked the picture of famous actor and healthy people do not happen or your own image or that of the celebrities.

However, when the portrait was taught not altered and only one in which the facial contour can be seen, there is a hypo activation of brain regions involved in this process.

On the other hand, deviations from the unaffected were more marked the greater the severity of the symptoms of those who believed deformed.

These abnormal patterns of activation show that people with the disease have difficulties in extracting information from a face. “These individuals perceive the details and have fundamentally damaged the ability to contextualize them within a whole,” the authors note.

The findings of this study show some similarities with the observed brain activity in individuals with obsessive-compulsive disorder. It is hypothesized that both disorders respond to similar neurological mechanisms.

A group of researchers identified brain regions modulated literacy, located where the expertise lies in the vocabulary and visual recognition.

The scientists conducted experiments to locate the footprint of learning to read and write public so the Spanish newspaper El Pais.

For this research were used functional MRI techniques in the brains of 63 volunteers Brazilian and Portuguese: 11 illiterate adults literate and 22 and 31 who learned to read and write for children.

The study found that literacy improves the function of speech, but do not yet know whether these changes in brain anatomy, decrease or no capacity, for example, to recognize faces.

Stanislas Dehaene researcher at the University of Paris-Sud and a group of leading scientists in their research published in the journal Science, which not only differences were found in the brain between the illiterate and literate, but also differences in those who learned adults.

During testing, the scientists presented to the 63 different people face recognition tasks, math problems and answer phrases heard and read.

Literacy, acquired either in childhood or adulthood, strengthens the brain’s response in several ways, Dehaene and colleagues explain.

Since learning to read reorganizes the visual cortex, but also allows sentences written answers to activate the entire network of spoken language in the left hemisphere of the brain.

A nerve that is very similar to a cable television cable. There are many small wires inside a large envelope. The strings carry messages, or small electrical impulses, to the end, just as the power cable brings a picture to your TV. This process must occur for the courage to stay healthy. If something causes pinched nerves, the nerves become inflamed and can no longer transport messages. The nerve starts to get sick. If you do not regain its ability to transfer, you begin to die. This causes the skin to feel numb and muscles to become weak. Cases

There are a number of compressed nerves. In general, the pinch occurs when there is pressure on the nerve from the surrounding tissue. This tissue may be bone or cartilage, muscle or tendon, or swelling of the nerve sheaths of tight places.
Some common causes of nerve pressure are soft tissue injuries, poor posture, repetitive jobs, sports, and obesity. A number of pregnant women also experience this condition as the in utero growth put additional pressure on their body. This pressure is quickly removed after birth. hard tissue pressure may come from a herniated disc or bone spurs, spinal arthritis. Carpal tunnel in the hand is another common example of compressed nerves. Inflammation in the tunnel wrist pinches the nerves passing through the tunnel and into the hand. The brain stops receiving signals from the hand and numbness is the main symptom.

most common symptoms of pinched nerves are pain, numbness, tingling, or burning sensations of hot and cold. In the lower back, felt like a pinched nerve numbness running down my leg or even as painful muscle spasms. This same feeling is felt by the running backs with their arms in case the upper body.

Compressed nerves can recover without permanent damage if the pressure is relieved. This can be done through surgery, the change of activity, medications such as cortisone, and sometimes even through the simple application of hot packs and cold. If the pressure is not relieved, there can be permanent nerve damage and chronic pain.

The treadmill training with or without partial suspension system achieves a positive weight on the role and spatial parameters of gait in children with cerebral palsy (ICP) and also seems to cause no adverse events.

However, in comparison with other methods of physical therapy, placebo or no treatment, the results of this study are, in most cases, not significant.

In this article, published in Journal of Neurology, included the results of randomized controlled trials or non-randomized controlled trials but autoemparejados from various databases.

Specifically, it included six articles and 127 participants were recruited.

In the systematic review the authors found some limitations that require careful reading of the information provided.

Of the constraints encountered, include the small number of items that recruit few patients, and in addition there is a large clinical diversity, many of these trials did not describe relevant data necessary for critical reading.

Dizziness is a feeling of instability, as one walks on cotton, in high and low. These can occur separately or together, and the vast majority of cases are of benign origin, ie, not a brain problem, but on one condition at the ear or vestibular nerve, which is carrying the information from ear to the brain.

The most common causes of vertigo or dizziness of non-cerebral origin (peripheral vestibular syndrome or SVP) are of viral origin (vestibular neuronitis, a viral inflammation of the nerve), at the microscopic mechanical disorders of the ear (benign paroxysmal positional vertigo), by increasing pressure of the endolymph which is a liquid in the internal system of the ear (Meniere’s disease), trauma (vertigo post TEC), infectious (syphilis) and others.

The SVP is often accompanied by severe nausea, vomiting, sweating, cold and long malaise. Depending on the cause, can last a couple of days, or chronic. It is with rest, light food and drugs that decrease the dizziness / vertigo (antivertiginosos) and drugs that reduce nausea (antiemetic) and the prognosis is generally good.

Then there is the vertigo of cerebral origin (central vestibular syndrome or SVC) which corresponds to less than 20% of all attacks of vertigo or dizziness.

May be secondary to brain tumors (particularly in the cerebellum or brain stem structures that are in the lower part of the brain), stroke or brain hemorrhage, multiple sclerosis, some types of epilepsy and others. Obviously having a problem to the brain, the prognosis is not as good as the SVP.

Depending on the cause you choose the most appropriate treatment for each patient (tumor surgery, antithrombotic agents in stroke, multiple sclerosis, interferon, etc..) Plus the same drugs used and Antiemetics antivertiginosos in the SVP. The SVC is usually more difficult to manage and takes longer to recover, in some cases may be chronic, ie with permanent vertigo.
