Understanding How Your Brain Works: Here is the 21st century managing a number of new discoveries, like landing on Mars, making vaccines for deadly viruses in less than a year and cars driving themselves. But at the same time you find many believing in outdated beliefs and myths that seems to be pulling you two steps backward after you have taken a step forward.
It is normal to be wrong in the scientific process. Scientists work with the tools that they have, till the time they get new tools that can extend their senses. This helps them to further probe precisely, deeply and broadly.
Here are three myths of the working of the brain.
Specific Parts of the Brain have Psychological Jobs Specified
If you follow this myth, the brain is considered to be similar to a jigsaw puzzle, each of the part with a definite mental function, one piece for emotion, one for vision and another for memory. This myth was popular in the 19th century and was called phrenology.
This myth has been discarded at present. Scientist now you know that the brain is one network of multiple neurons. Most of these neurons have a number of jobs, not only one.
Every neuron does not do all the jobs, but there is more than one job. For example, a brain region that is for vision, called the primary visual cortex, also has to carry information about touch, hearing and movement.
How Your Brain Works to the Events in the World
This means, you go about your day to day activities with certain parts of your brain being “OFF”. Then a happening around you make these parts of the brain switch “ON”.
You need to know that brains do not work by response and stimuli. All the time, the neurons fire at different rates, making various predictions. Every moment the brain uses the information available (situation, state of your body and memory), to guess what can happen the next moment. If the guess is correct the brain starts launching the next action of your body and creates what you feel, hear and see. If the guess is wrong, the brain corrects itself and makes better predictions the next time.
If the brain does not correct itself, you might hear or see things that are not present, or even probably, do something without intending to do so.
In short, your experiences of today lead to tomorrow’s actions.
Division between Body Disease and Mind Disease
Neuroscientists have found that the brain networks controlling your body and mind are the same. One example is the anterior cortex. The neurons participate in the different functions that are psychological in nature and also regulate your hormones, organs and the immune system to keep you well and alive.
All the experiences that are mental have physical causes, and the physical changes have consequences mentally.
The boundary is porous between mental and physical when talking about illness.
Science works by not only prediction but also correction, like your brain.
