Why Is The Brain Important

Don't Miss

One Of My Favorite Lines In Your Book Is People Are Like Plants Blossoming Or Fading With The Weather There Is Even A Connection Between Temperature And Violence Isnt There

It goes without saying that whats outside the body also influences the mind. The environment floods the brain with the equivalent of about 10 megabytes of information per second. A lot of that input remains subconscious. One example is temperature. We can feel when it gets too hot, but relatively subtle differences in temperature are often imperceptible to us.

A study by Soloman Hsiang of Princeton showed how a slight difference in temperature can dramatically influence incidences of violence and aggression. A couple of the studies he cited involved firearms training for police in the Netherlands. Changing the room temperature in which they were doing their exercises made them fire their guns more or less.

Why You Need To Observe Brain Injury Awareness Month

Did you know that almost 11,000 people in Canada die as a consequence of Traumatic Brain Injury every year? Letting people know about each and every aspect of Traumatic Brain Injury is very important. People all over Canada observe Brain Injury Awareness Month in the month of June every year. During this month, people across the nation work hard to educate people about the importance of Brain Injury Awareness. Apart from this, many organizations have come forward to promote advocacy.

Talking about the main objective of Brain Injury Awareness Month, well, this month gives people the opportunity to eliminate all the stigmas that have a close connection with brain injuries. People can suffer from different types of brain injuries and therefore, every time, different cases will appear. Therefore, this Brain Injury Awareness Month is fully dedicated to improving the overall awareness of brain injuries. During this month, there are many organizations that provide high-quality support to people who suffer from brain injuries. Moreover, understanding the needs of those people will also help to keep the upcoming situation in good shape. It is a very time-consuming and complicated task to change the worlds perspective on brain injuries.

Healthy citizens are the greatest asset any country can have.

What’s The Difference Between The Left Brain And Right Brain

The human brain is divided into two hemispheres, the left and right, connected by a bundle of nerve fibers called the corpus callosum. The hemispheres are strongly, though not entirely, symmetrical. Generally, the left brain controls the muscles on the right side of the body, and the right brain controls the left side. One hemisphere may be slightly dominant, as with left- or right-handedness.

Related: What’s the difference between the right brain and the left brain?

The popular notions about “left brain” and “right brain” qualities are generalizations that are not well supported by evidence. However, there are some important differences between these areas. The left brain contains regions that are involved in language production and comprehension and is also associated with mathematical calculation and fact retrieval, Holland said. The right brain plays a role in visual and auditory processing, spatial skills and artistic ability more instinctive or creative things, Holland said though these functions involve both hemispheres. “Everyone uses both halves all the time,” he said.

The human brain has two hemispheres, which are popularly considered to be responsible for completely different set of skills, but there’s little scientific research to support that notion. 

The Book A Change Of Heart Revealed Something Extraordinary: That When A Person Has A Heart Transplant They Can Also Feel Like Theyve Inherited Some Of The Donors Personality Traits Do You Think That This Is Possible

As a scientifically minded skeptic, I dont believe its possible or have a plausible explanation for it. However, its clear that the author of the book, Claire Sylvia, experienced a tremendous emotional upheaval. Whether she gained the memories of the donor seems highly doubtful. But the fact that the transplant caused emotional upheavalthat is something I dont dispute. I cite a study of a large population of heart transplant recipients, where about 20 percent reported personality changes.

If you look at other transplant patients, theyre also reporting significant changes in mood, some for pretty well defined physiological reasons. One example is liver transplants. The liver is involved in detoxifying the blood and toxins in the blood affect the brain. So, if you correct somebodys malfunctioning liver, you also change their cognitive landscape.

The Cerebellum The Back Of The Brain

Why is Preschool Important?

Behind the cerebrum at the back of the head is the cerebellum. In Latin, cerebellum means little brain. However, the cerebellum contains more nerve cells than both hemispheres combined. The cerebellum is primarily a movement control center, responsible for:

  • Voluntary muscle movements
  • Fine motor skills
  • Maintaining balance, posture, and equilibrium

Unlike the cerebrum, the left cerebellum controls the left side of the body, and the right cerebellum controls the right side of the body.

Tissues Covering The Brain

Within the skull, the brain is covered by three layers of tissue called the meninges.

No computer has yet come close to matching the capabilities of the human brain. However, this sophistication comes with a price. The brain needs constant nourishment. It demands an extremely large amount and continuous flow of blood and oxygenabout 25% of the blood flow from the heart. The overall energy consumption of the brain does not change much over time, but certain areas of the brain, use more energy during periods of increased activity . A loss of blood flow to the brain for more than about 10 seconds can cause a loss of consciousness.

Lack of oxygen or abnormally low sugar levels in the blood can result in less energy for the brain and can seriously injure the brain within 4 minutes. However, the brain is defended by several mechanisms that can work to prevent these problems. For example, if blood flow to the brain decreases, the brain immediately signals the heart to beat faster and more forcefully, and thus to pump more blood. If the sugar level in the blood becomes too low, the brain signals the adrenal glands to release epinephrine , which stimulates the liver to release stored sugar.

It Is A Myth That Humans Only Use 10% Of Our Brain

We actually use all of it. Were even using more than 10 percent when we sleep. Although its true that at any given moment all of the brains regions are not concurrently firing, brain researchers using imaging technology have shown that, like the bodys muscles, most are continually active over a 24-hour period.


The Architecture Of The Brain

The brain is like a committee of experts. All the parts of the brain work together, but each part has its own special properties. The brain can be divided into three basic units: the , the , and the .

The hindbrain includes the upper part of the spinal cord, the brain stem, and a wrinkled ball of tissue called the cerebellum . The hindbrain controls the bodys vital functions such as respiration and heart rate. The cerebellum coordinates movement and is involved in learned rote movements. When you play the piano or hit a tennis ball you are activating the cerebellum. The uppermost part of the brainstem is the midbrain, which controls some reflex actions and is part of the circuit involved in the control of eye movements and other voluntary movements. The forebrain is the largest and most highly developed part of the human brain: it consists primarily of the cerebrum  and the structures hidden beneath it .

When people see pictures of the brain it is usually the cerebrum that they notice. The cerebrum sits at the topmost part of the brain and is the source of intellectual activities. It holds your memories, allows you to plan, enables you to imagine and think. It allows you to recognize friends, read books, and play games.

Pituitary Gland Controls Growth

The pituitary gland is very small only about the size of a pea! Its job is to produce and release hormones into your body. If your clothes from last year are too small, it’s because your pituitary gland released special hormones that made you grow. This gland is a big player in too. This is the time when boys’ and girls’ bodies go through major changes as they slowly become men and women, all thanks to hormones released by the pituitary gland.

This little gland also plays a role with lots of other hormones, like ones that control the amount of sugars and water in your body.

Why Is Brain Health Important

Even before you leave the womb, your brain works throughout your life to control your body’s functions and helps you understand and interact with the world around you. Maintaining a healthy brain will help your mind stay clear and active, so that you can continue to work, rest and play.

The importance of heart health has long been promoted, but brain health is just as crucial for our ability to think, act and live well. Brain health is about reducing risk factors, keeping your mind active and getting the very best out of your brain as you get older.

Chronic conditions like diabetes and high blood pressure together with family history and the way we live our lives have an impact on the healthy function of our brains. All of these factors can increase the risk of developing diseases like Alzheimer’s and vascular dementia. We can’t change our genetic heritage, but we can make lifestyle changes that can reduce the risk of developing dementia and mild cognitive decline. Caroline Abrahams, director of Age UK said:

The changes that we need to make to keep our brains healthy are already proven to be good for the heart and overall health, so its common sense for us all to try to build them into our lives.

How Many Brain Cells Does A Human Have

The human brain contains about 86 billion nerve cells called “gray matter,” according to a 2012 study published in the Proceedings of the National Academy of Sciences. The brain also has about the same number of non-neuronal cells, such as the oligodendrocytes that insulate neuronal axons with a myelin sheath. This gives axons a white appearance, and so these axons are called the brain’s “white matter.” 

Does Brain Health Make A Difference

forms of dementiaage-related cognitive decline

Regular physical exercise, cutting bad habits like cigarettes and alcohol, eating a balanced diet and staying socially active can all boost brain health. There are no guarantees, we’ve all seen people who have still been affected by Alzheimer’s, despite being healthy and clean living. However, living well does make a real difference. Statistically, a healthy lifestyle will not just reduce your risk of dementia, it will also protect against other serious conditions like diabetes, heart disease and cancer.

The Cerebellum’s Balancing Act

Why Early Childhood Years Are Important for Brain ...

Next up is the cerebellum. The cerebellum is at the back of the brain, below the cerebrum. It’s a lot smaller than the cerebrum. But it’s a very important part of the brain. It controls balance, movement, and coordination .

Because of your cerebellum, you can stand upright, keep your balance, and move around. Think about a surfer riding the waves on his board. What does he need most to stay balanced? The best surfboard? The coolest wetsuit? Nope he needs his cerebellum!

One Of The Underlying Concepts In Your Book Is What You Call The Cerebral Mystique Can You Explain What It Means And Why This View Of The Brain Is Distorting Our Real Natures

This book is largely about two opposite ideas: the biological mind centered on the brain, in which influences from the rest of the body and outside the body shape what we think and do, and the cerebral mystique, a complex of stereotypes and ideals about the brain, which tend to treat it as an isolated and all-powerful entity, almost like a modern version of the soul.

The problem with having a dualistic view of the brain and its relationship to the physical body, and the physical world, is that it makes us see ourselves as unnaturally self-contained, both as minds and as autonomous agents. In other words, we view ourselves as things that operate from within, so were less sensitive to things that influence us on the outside. The idea that the brain is a machine, an abstract entity like a giant supercomputer, has been around for a while, basically since computers. Other people have used a quantum analogy for the brain. But the idea of the brain as a computer is the most common in this day and age.

How Does Aging Affect The Brain

As we pass the age of 40, the volume and weight of our brain declines by around 5% per decade and progressive neurodegenerative alterations gradually reduce cognitive and functional abilities.

The Journal of International Medical Research in 2007, reported that deficiencies in DHA and other key vitamins and minerals may impair our cognitive performance, resulting in age related cognitive decline.

How Else Could You Help Your Brain

There is a variety of other ways you can help your brain focus, retain information, and even boost memory. One of the best ways, and the easiest, is to exercise your brain regularly. This can be done by doing puzzles, but it is also something you do every day. Trying to figure out jokes or riddles are great exercises for the brain, and theyre fun to do. Your brain also gets exercise when you have fun or laugh, so get out, join some friends and have fun. Youll be working out your brain without even realizing it. There are many resources out there to help you exercise your brain. Crosswords, number challenges, problems to solve and on-line games are all great examples.  For a great free on-line brain workout go to , they have a large variety of fun and sometimes addictive brain training games.

Short Term Memory Lasts About 20

This has to do with your brains capacity for holding small amounts of information in the active mind. The brain keeps this information in an available state for easy access, but only does so for about a minute and a half. Most people hold memory for numbers around 7 seconds, and memory for letters around 9 seconds. In addition, the brain can store up to 7 digits in its working memory. That is why the telephone numbers in the United States are 7 digits long. Learn more about Memory Disorders.


The Importance Of Early Childhood Experiences For Brain Development

Children are born ready to learn, and have many skills to learn over many years. They depend on parents, family members, and other caregivers as their first teachers to develop the right skills to become independent and lead healthy and successful lives. How the brain grows is strongly affected by the childs experiences with other people and the world. Nurturing care for the mind is critical for brain growth. Children grow and learn best in a safe environment where they are protected from neglect and from extreme or chronic stressexternal icon with plenty of opportunities to play and explore.

Parents and other caregivers can support healthy brain growth by speaking to, playing with, and caring for their child. Children learn best when parents take turns when talking and playing, and build on their childs skills and interests. Nurturing a child by understanding their needs and responding sensitively helps to protect childrens brains from stress. Speaking with children and exposing them to books, stories, and songs helps strengthen childrens language and communication, which puts them on a path towards learning and succeeding in school.

When children are at risk, tracking childrens development and making sure they reach developmental milestones can help ensure that any problems are detected early and children can receive the intervention they may need.

You Conclude The Book With The Words The Brain Is A Biotic Organ Embedded In A Continuum Of Natural Causes And Connections That Together Contribute To Our Biological Minds Bring It Home For Us Alan; Explain Why It Is So Important To Understand That We Are Not Only Our Brains

My overarching theme is against narrow thinking. If we want to solve our problems, we shouldnt reduce them to problems of the brain. We need to keep a broad view, which recognizes how the brain is connected both to the body and to the environment; and look for solutions wherever they happen to lie. Explaining human behavior in terms of brain function alone stems from a kind of mystical view of the brain and keeps us from advancing in a way that science can encourage us.

Headaches Are Caused By A Chemical Reaction

Chemical activity in your brain, the nerves or blood vessels surrounding your skull, or the muscles of your head and neck can play a role in primary headaches. Serotonin is a chemical necessary for communication between nerve cells. When serotonin or estrogen levels change, the result for some is a headache or migraine. Serotonin levels may affect both sexes, while fluctuating estrogen levels affect women only.


Opportunities And Challenges Of Future Research On Brain Health

What is brain plasticity and why is it so important?

  • Lack of metrics or tools to comprehensively assess or quantify brain health

  • Little knowledge about the mechanisms of brain function and dysfunction

  • Few effective approaches to prevent and treat brain dysfunction in some major neurological disorders, such as dementia

  • Need to precisely preserve brain functions for people with neurosurgical diseases


Another difficulty in measuring brain health is that age, culture, ethnicity, and geography specific variations exist in the perception of optimal brain health. Patient centred assessment of brain function, such as self-perception of cognitive function and quality of life, should also be considered when measuring brain health. Universal acceptable, age appropriate, multidimensional, multidisciplinary, and sensitive metrics or tools are required to comprehensively measure and monitor brain function and brain health.

Meanwhile, the mechanisms behind the brain dysfunction in some neurological disorders are still not well understood, especially for mental and neurodegenerative disorders. Further investigation of the mechanisms of brain diseases may indicate approaches to treatment and improve brain function. Brain imaging based cognitive neuroscience may unravel the underlying brain mechanism of cognitive dysfunction and provide an avenue to develop a biological framework for precision biomarkers of mood disorders.

Is Perception A Controlled Hallucination

A great mystery of the human brain is linked with consciousness and our perception of reality. The workings of consciousness have fascinated scientists and philosophers alike, and though we are slowly inching closer to an understanding of this phenomenon, much more still remains to be learned.

Anil Seth, a professor of cognitive and computational from the University of Sussex in the U.K., who specializes in the study of consciousness, has suggested that this intriguing process is based on a sort of controlled hallucination, which our brains generate to make sense of the world.

Perception figuring out whats there has to be a process of informed guesswork in which the brain combines these sensory signals with its prior expectations of beliefs about the way the world is to form the best guess of what caused those signals.

Prof. Anil Seth

According to him, in delivering perceptions of things to our consciousness, our brains often make what you might call informed guesses, based on how it expects things to be.

This explains the uncanny effect of many optical illusions, including the now-notorious blue and black, or white and gold dress, when, depending on how we think the light in the picture is, we may see a different color combination.

Below, you can watch Prof. Seths 2017 TED talk. He explains how our brains make sense of the world around us and within us.

What Happens In My Brain When I Am Learning

Your brain is primarily composed of about 85 billion neurons, which is more than the number of stars you can see with the naked eye in the night sky. A neuron is a cell which acts as a messenger, sending information in the form of nerve impulses to other neurons . For example, when you are writing, some neurons in your brain send the move fingers message to other neurons and this message then travels through the nerves all the way to your fingers. The electrical signals that are communicated from one neuron to another are therefore what allows you to do everything you do: write, think, see, jump, talk, compute, and so on. Each neuron can be connected with up to 10,000 other neurons, leading to a large number of connections in your brain , which looks like a very dense spider web .

  • Figure 2 – Figure illustrating the very large number of connections between neurons.
  • Figure 3 – Figure illustrating the analogy of the trail in the forest.

How Can Eating Healthily Help Your Brain

One of the biggest things you can do to help your brain is to eat healthy foods. By making healthy selections for your meals, youre ensuring your body is receiving the nutrients it needs, especially your brain.  Youll find that when you eat healthily you have more energy and you can focus easier.

A consistent calorie intake from eating regularly aids the ability of the brain to send messages. The flow of these messages can be improved through eating omega -3 rich foods which boost the levels of myelin in the brain. Another key chemical in the brain which is linked to mood regulation is dopamine.  Reduced levels of this can result in growing feelings of hopelessness, negativity and annoyance. Boost dopamine levels with eggs, grains and meats.  Eggs are also linked to memory improvement. To read more about foods and their effects on the brain, there is a great article by the Daily Mail .

Eating healthily doesnt have to be difficult either. You dont need to follow a specific diet plan or pay a lot of money to have someone tell you what to eat. Instead, focus on eating healthy foods like vegetables, fruits, proteins, and other foods. Try to avoid going out to eat and instead cook something at home. By simply preparing your own meals, you can ensure youre using quality ingredients that will help both your body and brain stay healthy.

What Is The Human Brain Made Up Of

Our brain weighs around 1.5 kg and makes up 2% of our body weight. It requires around 20% of the energy produced by the body and therefore requires a large proportion of high-quality nutrients to maintain its efficiency.

The brain consists of around 90 billion neurons that are interconnected via trillions of neuronal bridges or synapses which carry electrical signals throughout the brain.

A surprising fact about the brain is that it is 60% lipid with a large percentage of this fat being the crucially important Omega 3 DHA .

On a daily basis, our brains are under constant attack by damaging oxidation, including the ongoing degradation of DHA within the brain. This degradation means that our DHA needs to be replaced continually and this key nutrient can only come from our diet. It is in effect, essential for the health of our brain and its performance.
