10 Debunked Myths: Myths About Our Brain

23 August 2013 9 Comments

     They are myths – falsehoods that are generally believed. Some myths are based on a modicum of accuracy; others originate from misinterpretations or from a demand for a good stable morsel. However, they go to be, they disguise themselves as truths and are passed along without doubt.
Myths about the mind have been particularly hard to debunk since the mind is not amply understood. However, over the previous few decades, scientists have learned much than enough to disgrace a few important mind myths:

Brain Myth #1: We only use 10 percent of our brain.brain
This is not true.
We take our entire mind. If you seem at a mind mapping you will discover that there are arrows and labels going all over the spot. There is not a region of the mind that isn’t doing its work. Besides, why would we get additional place? The brain, although only one percent of our body by weight, takes up to ten percent of our energy expenditure. With all that glucose getting burned just to hold it running, it’s a costly slice of equipment. If you oasis is considered this before, think about folk who have skull fractures in automobile accidents. When they go to the hospital, you never learn of a physician who says “easily, they got mind harm, but thank God it wasn’t the ten percentage they were really using!” Many folk discover the thought that they have undeveloped resources inspirational. I wear’s need to say you otherwise: you do get undeveloped resources. Perhaps we simply fulfil ten percentages of our prospective. However, the ‘fact’ that we only use 10% of our brain should be taken metaphorically, not literally.

Brain Myth #2: You can’t change your brain.
Your brain is constantly changing in response to your experiences, and it retains this basic “plasticity” well into old age.
Everything we do and believe about is reflected in patterns of action in our brains. Scientists can view these patterns in brain-imaging scans that indicate which parts of the mind are functioning during particular tasks. Changing our thinking or changing the way we behave causes corresponding changes in the brain systems involved. This is why therapy that teaches people to alter negative patterns of thought and behaviour (like cognitive therapy, for example) can be effective in treating some mental disorders.

Brain Myth #3: Memory decline is inevitable as we age.
Many folk hit really older age and are yet steep as always. Genetics understandably plays a character in “productive aging,” but how we survive our lives on a day-to-day ground is too crucial. To assist your mind age easily, you can:
– Perform physical exercise (especially aerobic exercise)
– Engage in intellectually stimulating mental activity
– Eat a healthy diet
– Maintain social connections
– Learn to manage stress
– Develop a positive attitude toward yourself and your world

Brain Myth #4: Brain damage is always permanent.brain
The brain can repair or compensate for certain losses, and even generate new cells.
It used to be believed that each person was born with a finite number of brain cells, so if you damaged any of them you operated on a deficit for the rest of your life. Less than 20 years ago, even major players in the neuroscience community believed that the brain could not generate new cells. Similarly, many scientists believed that the brain was unalterable; once it was “broken,” it could not be fixed. But recent discoveries have convinced most scientists to think differently. Evidence now shows that the brain remains “plastic” throughout life: it can rewire or change itself in response to new learning. Under certain circumstances, the brain can even create new cells through a process called neurogenesis.

Brain Myth #5: We need to buy very expensive stuff to improve our brains.
Every time we learn a new skill, theory or fact, we change the physical composition of our brains. Lifelong learning means lifelong neuroplasticity.
“Learning is physical. Learning means the modification, growth, and pruning of our neurons, connections–called synapses– and neuronal networks, through experience…we are cultivating our own neuronal networks.” – Dr. James Zull, Professor of Biology and Biochemistry at Case Western University,

Brain Myth #6: The brain does not make new brain cells.
This myth was usually believed for generations, but has recently been proven false. We now know that certain areas in the brain—including the hippocampus (where new memories are created) and the olfactory bulb – regularly make new brain cells. Many of these cells go on to become working part in brain-cell connections.

Brain Myth #7: Schools should just focus on basic skills like Reading and Math.
“Mental muscles,” such as working memory, are fundamental to educational performance and are currently overlooked by the school system.
“I don’t see that schools are applying the greatest knowledge of how minds work. Schools should be the best place for applied neuroscience, taking the latest advances in cognitive research and applying it to the job of educating minds.” – Dr. Arthur Lavin, Associate Clinical Professor of Pediatrics at Case Western School of Medicine.

Brain Myth #8: Playing Mozart to babies boosts their intelligence.
This is known as the ‘Mozart Effect.’ It was originally proposed by two researchers, Rauscher and Shaw, who reported a small gain for pre-schoolers who had listened to Mozart.
However, it turns out that their finding was merely a fluke (what researchers call a Type 1 error). In other words, a couple of the kids scored high on the day of testing, and a couple of other kids scored unusually low, for reasons that had nothing to do with the fact that Mozart was played.
Research into the subject has since found that there is no Mozart effect.

Brain Myth #9: Videogames are always a waste of time.
Scientifically-designed, computer-based programs can be a good vehicle for training specific skills. For example, it has been shown that short-term memory can be expanded by such programs.
“We have shown that working memory can be improved by training.” – Dr. Torkel Klingberg, Director of the Developmental Cognitive Neuroscience Lab at Karolinska Institute.

Brain Myth #10: Crossword puzzles, or our daily job activities, are the best way to keep one’s mind sharp.
Computer-based programs can be more effective at training specific cognitive skills.
“What research has shown is that cognition, or what we call thinking and performance, is really a set of skills that we can train systematically. And that computer-based cognitive trainers or “cognitive simulations” are the most effective and efficient way to do so.” – Dr. Daniel Gopher, Professor of Human Factors Engineering at Technion Institute of Science.
