Don't Miss

Some Key Neurotransmitters At Work

Is The Brain A Muscle?

Neurotransmitters are chemicals that brain cells use to talk to each other. Some neurotransmitters make cells more active while others block or dampen a cell’s activity .

Acetylcholine is an excitatory neurotransmitter because it generally makes cells more excitable. It governs muscle contractions and causes glands to secrete hormones. Alzheimers disease, which initially affects memory formation, is associated with a shortage of acetylcholine.

Glutamate is a major excitatory neurotransmitter. Too much glutamate can kill or damage neurons and has been linked to disorders including Parkinson’s disease, stroke, seizures, and increased sensitivity to pain.

GABA is an inhibitory neurotransmitter that helps control muscle activity and is an important part of the visual system. Drugs that increase GABA levels in the brain are used to treat epileptic seizures and tremors in patients with Huntingtons disease.

Serotonin is a neurotransmitter that constricts blood vessels and brings on sleep. It is also involved in temperature regulation. Low levels of serotonin may cause sleep problems and depression, while too much serotonin can lead to seizures.

Dopamine is an inhibitory neurotransmitter involved in mood and the control of complex movements. The loss of dopamine activity in some portions of the brain leads to the muscular rigidity of Parkinsons disease. Many medications used to treat behavioral disorders work by modifying the action of dopamine in the brain.

Surf Dance And Play Like Children

Researchers Tracy and Ross Alloway from the University of North Florida in the United States found that spending just two hours on a physical activity we enjoyed as children like climbing trees or running barefoot had strong effects on working memory, which saves memory. information and allows us to manipulate it.

prioritizes and processes information that allows us to ignore what is irrelevant and works on what is important, Tracy Alloway said, according to New Scientist.

The researchers found that when two activities are combined the results are more positive for the brain.

The secret is to challenge the sense of proprioception, which is our awareness of where the parts of our body are located.

This is how the exercises in which we need to think and balance are very effective for the brain.

According to Alloway, a good example is surfing.

To catch a wave, you have to pay close attention to the proprioceptive information or you will fall off the board you also have to decide what is the best position you will be in to ride the wave as well as to determine if another surfer has the priority to grab it Alloway said according to the trade publication.

Peter Lovatt, a psychologist studying the benefits of dance at the University of Hertfordshire in the UK, suggests putting on music and letting yourself be carried away by it.

Be Good To Your Brain

So what can you do for your brain? Plenty.

  • Eat healthy foods. They contain vitamins and minerals that are important for the nervous system.
  • Get a lot of playtime .
  • Wear a helmet when you ride your bike or play other sports that require head protection.
  • Don’t drink alcohol, take drugs, or use tobacco.
  • Use your brain by doing challenging activities, such as puzzles, reading, playing music, making art, or anything else that gives your brain a workout!

Can The Brain Improve With Exercise

A recent New York magazine story published by Pro Bronson and Ashley Merryman detailed an experiment where a teacher was able to impact math scores by having children read out loud a scientific paper on how the brain is a muscle that will respond to exercise. The knowledge of this opportunity encouraged students to work harder and a new improved trend was established.

In another world, far away, in the world of neuroscience, the idea that the brain is like a muscle has received an enormous amount of attention since the famous ferret experiment in 2000 that proved that the brain is basically tissue like muscle that can be called to action for any purpose. This is brain plasticity.

The obvious implication is that brain is like a muscle new tissue is available for a specific task if that task is exercised correctly. It is known for instance that violinists have much more brain activity related to movement of their fret-board fingering hand the accuracy and speed required for this exacting task is met by the brain devoting more resources to developing skills beyond what is needed for normal function.

What Happens When You Exercise Your Brain

Is The Brain A Muscle? The Truth About The Brain

Exercising your brain using cognitive training tools, which are also called brain training games or brain exercises, may help improve your cognitive functioning.

Some studies have found that brain exercises improve memory, executive functions, and processing speeds, while others have shown little to no effect.

The impact of brain exercises may have something to do with age. Some studies have shown an improvement in cognitive abilities in young people and older adults. Nouchi R, et al. . Brain training game boosts executive functions, working memory and processing speed in the young adults: A randomized controlled trial. DOI: 10.1371/journal.pone.0055518

Brain exercises may also be beneficial in slowing age-related changes in the brain and those associated with neurological conditions, such as Alzheimers disease and dementia.

A study published in 2017 showed that a brain-training intervention known as speed-of-processing training significantly reduced dementia risk. Edwards JD, et al. . Speed of processing training results in lower risk of dementia. DOI: 10.1016/j.trci.2017.09.002

If youre looking to exercise your brain, you dont necessarily need to resort to brain training games and apps.

Your brain is made up of different parts that all work together. Lets take a look at the different parts of the brain and what they do.

Smart Strategy: Think Of The Brain As A Muscle

8 February 07

Students who are told they can get smarter if they train their brains to be stronger, like a muscle, do better in school, a new psychology study shows.

Many people have various theories about the nature of intelligence. Some view it as a fixed trait, while others see intelligence as a quality that can develop and expand.

These ideas have can have a profound effect on the motivation to learn, said researcher Carol Dweck, a child and social psychologist at Stanford University.

“Those who follow a fixed theory are concerned with whether they look smart or dumb. They don’t enjoy tasks that are difficult, where if they have a setback they can look dumb,” Dweck explained. “Those who think intelligence is something you can cultivate are much more interested in being challenged than in just looking smart. They are much more resilient and persistent, and not as worried about making mistakes.”

  • Mysteries of the Mind

Dweck had an experience in 6th grade in Brooklyn that made her want to understand with views people held on intelligence.

“My teacher seated us around the room in IQ order,” she told LiveScience. “All the responsibilities were assigned to high-IQ students. Looking back, I always enjoyed learning before, but the experience in that class wasn’t about learning, it was about feeling like you had to always look smart or get demoted to one of the lesser seats.”

Physical Exercises To Keep Your Brain In Shape

There are exercises that promise to train the brain such as electronic brain teasers or those that only require a pencil to complete. However, scientists do not seem to fully agree on its efficacy. What they do agree on is that physical exercises contribute to a healthier brain.

A study by the Beckman Institute at the University of Illinois in the United States, released Monday, found that physically fit people tend to have greater brain volume and more intact white matter than people who do not exercise.

According to the study, in which 100 people between the ages of 60 and 80 were analyzed, older adults who regularly engage in moderate to vigorous physical activities have greater brain activity even when at rest than those who do not exercise.

Greater activity in the brain is associated with better cognitive performance.

In the article: Why choosing the right workout could fine-tune your brain of the specialized magazine New Scientist, a series of scientific studies is listed that confirm that physical exercises have an effect on the brain.

15 years ago, the publication notes, a study with mice showed that exercise causes neurons in the hippocampus to secrete a protein called brain-derived neurotrophic factor , which promotes the growth of neurons.

The mice showed improvements in memory when they were put through mazes, says New Scientist.

Strengthening Your “Concentration Muscle”: Boosting Brain Power through Better Focus

The cerebrum is divided into two halves: the right and left hemispheres . The left hemisphere controls the right half of the body,and the right hemisphere controls the left half of the body.

The two hemispheres are connected by a thick band of neural fibers known as the corpus callosum,consisting of about 200 million axons. The corpus callosum allows the two hemispheres to communicatewith each other and allows for information being processed on one side of the brain to be shared with theother side.

Figure 2. The cerebrum is divided into left and right hemispheres. The two sides are connected by the nerve fibers corpus callosum.

Hemispheric lateralization is the idea that each hemisphere is responsible for different functions. Each of these functions are localized to either the right or left side.

The left hemisphere is associated with language functions, such as formulating grammar and vocabulary, and containing different language centres .

The right hemisphere is associated with more visuospatial functions such as visualization, depth perception, and spatial navigation. These left and right functions are the case in the majority of people, especially those who are right-handed.

The Biggest Part: The Cerebrum

The biggest part of the brain is the cerebrum. The cerebrum is the thinking part of the brain and it controls your voluntary muscles the ones that move when you want them to. So you need your cerebrum to dance or kick a soccer ball.

You need your cerebrum to solve math problems, figure out a video game, and draw a picture. Your memory lives in the cerebrum both short-term memory and long-term memory . The cerebrum also helps you reason, like when you figure out that you’d better do your homework now because your mom is taking you to a movie later.

The cerebrum has two halves, with one on either side of the head. Scientists think that the right half helps you think about abstract things like music, colors, and shapes. The left half is said to be more analytical, helping you with math, logic, and speech. Scientists do know for sure that the right half of the cerebrum controls the left side of your body, and the left half controls the right side.

The Cell Structure Of The Brain

The brain is made up of two types of cells: neurons and glial cells, also known as neuroglia or glia. The neuron is responsible for sending and receiving nerve impulses or signals. Glial cells are non-neuronal cells that provide support and nutrition, maintain homeostasis, form myelin and facilitate signal transmission in the nervous system. In the human brain, glial cells outnumber neurons by about 50 to one. Glial cells are the most common cells found in primary brain tumors.

When a person is diagnosed with a brain tumor, a biopsy may be done, in which tissue is removed from the tumor for identification purposes by a pathologist. Pathologists identify the type of cells that are present in this brain tissue, and brain tumors are named based on this association. The type of brain tumor and cells involved impact patient prognosis and treatment.

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.

A Stubbornly Persistent Myth

Cartoon Brain With Muscles

Thinking about learning Latin for the sake of building mental muscles is so far from the current educational norm, that it can feel almost quaint. We see ourselves as above falling for such a simplistic error in our own ideas about learning, right?

Yet, its exactly a revival of this failed analogy that you see popping up in all sorts of places.

Critical thinking is often touted as the must-teach skill in high-schools and colleges. And while learning logic and syllogisms may be useful in some particular settings, the idea that this exercise trains us to be good thinkers generally was given a thrashing almost a century ago.

Similar are the cries for universal training in programming. While programming is definitely a useful skill and there are many practical applications for programming, thats not the only reason offered for it. Programmers have better thinking skills, it has been argued, and that teaching kids to code will help them think logically about the world. The muscle metaphor persists.

Brain-training games premise their entire application on the idea that one can improve cognition like a muscle, training on irrelevant mental tasks to improve brain strength. Some studies do even suggest that they may work on tests of general reasoning.

Is The Brain A Muscle The Truth About The Brain

Is the brain an organ? Or is it a muscle? And does it need to be trained and maintained?

Oh, the burning questions! Whether its a myth or a persistent metaphor, there is a common belief that the brain is a muscle.

The belief that the brain is a muscle may have stemmed from the phrase exercise your brain or your brain is like a muscle. And although it makes sense as a metaphor, the reality that science teaches us tells a different story.

The Geography Of Thought

Each cerebral hemisphere can be divided into sections, or lobes, each of which specializes in different functions. To understand each lobe and its specialty we will take a tour of the cerebral hemispheres, starting with the two frontal lobes , which lie directly behind the forehead. When you plan a schedule, imagine the future, or use reasoned arguments, these two lobes do much of the work. One of the ways the frontal lobes seem to do these things is by acting as short-term storage sites, allowing one idea to be kept in mind while other ideas are considered. In the rearmost portion of each frontal lobe is a motor area , which helps control voluntary movement. A nearby place on the left frontal lobe called Brocas area allows thoughts to be transformed into words.

When you enjoy a good mealthe taste, aroma, and texture of the foodtwo sections behind the frontal lobes called the parietal lobes are at work. The forward parts of these lobes, just behind the motor areas, are the primary sensory areas . These areas receive information about temperature, taste, touch, and movement from the rest of the body. Reading and arithmetic are also functions in the repertoire of each parietal lobe.

As you look at the words and pictures on this page, two areas at the back of the brain are at work. These lobes, called the occipital lobes , process images from the eyes and link that information with images stored in memory. Damage to the occipital lobes can cause blindness.

Fixing Muscle And The Brain

Nenad Bursac and Tatiana Segura are engineering hydrogel microenvironments to physically and chemically support the growth of skeletal muscle and brain tissue

With the number of times the word gel comes up in the research of Nenad Bursac and Tatiana Segura, one would be forgiven for thinking they might work in the haircare or running shoe industries. Their gels, however, are aimed at much more difficult tasks than holding hair styles or cushioning feet.

Bursac and Segura, both professors of biomedical engineering at Duke University, are two of the leading researchers working to grow functional tissues both inside and outside of the human body. While the gels being engineered in their laboratories are initially more liquid than solid, they promptly solidify to provide a crucial three-dimensional scaffolding for cells to organize and grow. And by adding the perfect combination of growth factors, enzymes, nutrients and supporting cells, their laboratories are successfully engineering some of most challenging human tissues, including skeletal muscle and brain matter.

The method took years to develop, with the researchers making educated guesses and taking baby steps toward their goal. The difference-maker was their unique cell culture conditions and 3-D matrix, which allows the cells to grow and develop much faster and longer than the 2-D approaches that are more typically used.
