Anything you ever learn in life occurs through a physical change in the wiring of your brain. The brain is the final processing centre of the streams of new information received through your senses. The books you read, the words you hear and the movements you make are converted into electrical signals which travel to your brain for processing.
Further, the brain has a top-down influence on learning too. Previous experiences which have shaped your brain and the current conscious state your brain is in, act to influence how new information is experienced and stored. In this sense, the brain is a true integrator of all our new knowledge.
Your creativity, reasoning, planning, debating and socialising are brain based processes too. Your motivation to study, whatever it is you wish, comes from the limbic areas of your brain – not some abstract, mythical place or entity. The decision you took to pick a particular career or area of study was carried out with your noggin.
The brain is where everything significant happens; it is the final determinant of your cares and decisions and is the main player in determining what you study and which career you choose. The brain is the tool you use to make any decision; its physiological state determines what motivates and interests you, simulates scenarios, balances pros and cons and outputs its decision. The brain decides whether you study Law, Computer Science or Spanish. However, surely there is no more interesting or beneficial thing to understand than the physical tool which determines everything meaningful about your life – the brain.
Not convinced? Other reasons Neuroscience is the most important thing to study:
1) Neuroscience is the final frontier. Humans have mapped the earth, much of nearby space, deciphered the human genome and understood the workings of most of our biology. However, it is the most fascinating organ of ours, the brain, which remains most mysterious.
2) Neuroscience offers huge benefits in medicine for many. Estimates suggest, over 1 in 3 people will suffer from a mental illness at one point in their lifetime. Treatments remain in their infancy and predominantly treat symptoms, not cause. Often, researchers do not fully understand why treatments which work, do. Also, dementia is on the rise with ever-increasing lifespans. By 2050, the incidents of Alzheimers are forecast to quadruple worldwide. Advances in neurological therapeutics have not kept pace with advances in some other areas of medicine.
3) Neuroscience research helps us improve our own brains. From the non-invasive processes of changing the way we think by becoming aware of an improved way of thinking, to installing biological neuroprosthetics which may enable a ‘memory upgrade’ or a ‘pattern recognition enhancer’.
4) Neuroscience understanding will advance Artificial Intelligence (AI) research. Understanding how we are intelligent enables us to make machines intelligent. Advancing machine intelligence has the potential to solve many of man’s problems, with machines performing many tasks for humans and speeding up human development.
5) Understanding neuroscience, helps you understand yourself. Who are you? I would say you are a puddle of thoughts, memories, goals, feelings, sensations, cares and conscious awareness. All of these phenomena are the result of brain based physiological processes. If you understand how these work, you will understand yourself better.
6) Any drive you have is the result of how your brain is currently wired. This, neuroscientific enquiry can help understand. Studying neuroscience may provide an avenue to look into your own drive and psych and, in the distant future, possibly tamper with it for your own good.
Hence, to spell it out, I believe neuroscience is the most important thing to study.
