What are the Limits of the Human Brain - How the Brain Overcomes its own Limitations?

Imagine, you are trying to write your name on the mirror so can you read it accurately. You have all the visual information you need in your brain, and you are the supporter of writing your name. However, this task is not very easy for most of the people. This is because it requires a mental change in the brain which is not familiar with it. Using whatever is seen in the mirror, it is used to guide your hands precisely to write backward. We will discuss in this article how the brain overcomes its own limitations, before that, it is necessary to know what the brain limitations are, and how can we determine them?

Limitations of the human brain 

There are limitations on how well the brain adapts during learning? These constraints and restrictions are important to determine whether it is easy to learn new skills or difficult. In any other learning and teaching situations, you are not much harder than the restrictions you get. It will take time to become adept and get awareness, skill building, and appropriate ways. But it can be learned in a fun and helpful manner. To understand how brain activity can be "flexed" during the learning process to develop a better technique for treatments of stroke and other brain injuries. Brain-based learning is, in fact, a new model of teaching that integrates instruction in the best way in which the brain learns and stores information. Although brain-based education takes into account that the brain retains the best information, it is also subject to its errors and weaknesses. The human brain has not been designed optimally, nor has it evolved for formal classroom instruction purposes. Thus, there really are limitations of brain-based learning because it takes people to implement it and we all have limitations of our time and resources. If there were no limitations of brain-based learning, as with all learning, then everyone could potentially know everything.

Limitations to Attention

Short-term memory is something like a virtual flash memory on your computer. It is very fast, instantly reflects what it has gone through, but there is a work involving the transfer of content to long-term storage. In addition, there are limitations to their ability. Your computer's hard drive can store a lot of information in the long run, but the limited size of virtual flash memory focuses on speed and immediate use - not on long-term storage. So it is with the brain. Most of us cannot concentrate and pay attention for long periods because of the limitations caused by deviations from the environment and from the extensive breakthroughs of memory, which distract the mind. Although it is difficult for people to maintain focus for long periods, we only have the ability to push this ability to the top in times of need.

Limitations of Needs

If the children are emotionally troubled, hungry, or scared, then their ability to learn is close to the bottom. The result is simple; Many children are not in a mental or emotional "state of mind" to learn well. But it can be solved by understanding what they do in the process of the learning process, you can learn to control their negative effects.

Limitations of Culture

Children in poverty are different, whether they are rural or urban, generation or circumstance, and complete or relative poverty. Most neuroscience guides show that the experience of poverty changes your brain in areas such as emotion, language, memory, pressure, and processing. This type of children suffers more in school compared to other children.

Limitations of Environment

Our brain has been designed to give immediate attention to things related to movement, emotion, innovation, contrast, and social attraction. A school has chalk-a-block with those variables. No wonder students have trouble concentrating! In essence, we all are born with a practical, low attention period. The school cannot be challenging only for ADHD children. It is difficult to pay attention to and concentrate, usually with great excitement in life or the classroom. Learning to control that variable is a part of the principles and strategies of brain-based learning techniques.


How Brain Overcomes Its Own Limitations

The study reveals how the brain overcomes its own limitations

(1) Recently, the Massachusetts Institute of Technology (MIT) neuroscientists have discovered how the brain tries to compensate for the weakness of his performance in tasks that require this kind of complex transformation. As in other types of situations in which you do not trust the rules, the brain tries to overcome its difficulties based on past experiences. Previous research has revealed several strategies that help the brain compensate for this uncertainty. Using a framework known as Bayesian integration, the brain combines several; conflicting parts of the information and their values according to their reliability. For example, if the information is provided from two sources, we will rely more on information that we believe is more reliable.

Noisy computations

Neuroscientists have known for decades that the brain does not honestly copy what the eye sees or the ears hear. Instead, there is a great deal of "noise" - random fluctuations of electrical activity in the brain, which can come from ambiguity or uncertainty about what we see or hear. This uncertainty also arises in social interactions, and we try to explain the motives of others or remember the memories of past events. In other cases, such as making movements when we are not sure exactly how to proceed, the brain depends on the average of its previous experiences. For example, when you access the light switch in an unfamiliar dark room, we will move our hand toward a certain height and close to the door frame, where previous experience indicates a light key. Noise can also occur in the mental transformation of sensory information into a kinetic scheme. In many cases, this is a simple task where noise plays a minor role - for example, accessing a bowl you can see on your desk. However, for other tasks, such as a mirror-writing exercise, this conversion is more complex.

This type of mental transformation is what the researchers identified for their exploration in the new study. To do this, they asked the subjects to do three different tasks. For each, they compared the performance of participants in a copy of the task by which it was easy to map sensory information to motor commands, and the version that required additional mental transformation. In one example, researchers first asked participants to draw a line along the same length as the line that was displayed, which was always between 5 and 10 centimeters. In the most difficult version, ask them to draw a line 1.5 times longer than the original line. The results from this group of experiments, in addition to the other two tasks, show that in a version that required difficult mental transformations, people changed their performance using the same strategies they use to overcome noise in perception and other fields. For example, in the task of drawing lines, where participants had to draw lines ranging from 7.5 to 15 centimeters, depending on the length of the original line, they tended to draw lines closer to the average length of all the lines they had previously painted. This made their responses generally less variable and more accurate as well.

Noise reduction

The new study led researchers to assume that when people become very good on a task that requires complex computing, the noise will become smaller and less harmful to overall performance. This means that people trust their calculations more and stop relying on averages. Researchers are now planning further study on whether people bias decreases as they learn to perform a complex task better. In experiments, they performed for the Nature Communications study found some preliminary evidence that was trained musicians performed better in a task involving the production of time periods in a specific duration.

Mehrdad Jazayeri, a member of MIT's McGovern Institute for Brain Research and a senior author of the study said in his statement “It has been shown before that all these strategies work together to increase the bias toward a particular result, making our overall performance better because it reduces the change. If you do something that requires a more difficult mental shift, thus creating more uncertainty and more variation, you rely on your preconceptions and bias yourself towards what you know how to do a good job, in order to make up for that change. Your performance will be variable, not because you do not know where your hand is, not because you do not know where the picture is. It contains a completely different form of uncertainty, which relates to processing information. The act of making mental shifts of information clearly leads to change. This decline to the average is a very common strategy to make performance better when there is uncertainty. Our expectations are that bias will go away, because this account is no longer a noisy computation. You believe in that; you know that the computation works well.
