If you feel inclined towards neuroscience then make sure you love studying for long hours. Read on to know more about a career in Neurosciences.
Neuroscientists study how the human nervous system works, what is its structure, how it impacts other parts of the body and what causes behavioral and emotional changes, etc. As a Neuroscientist, you would study several aspects of neurosciences in terms of behavior, cognition, cells, molecules, anatomy, linguistics, and psychology among many others.
Why Become a Neuroscience/Neurobiology?
A Neuroscientist is a researcher who studies biochemical aspects of the brain and its impact on behavior and other cognitive functions like learning, memory, thought, perception, language understanding, and problem-solving etc. Neuroscientists study how the nervous system works and conduct research to learn about the structure, function, genetics and physiology of the nervous system. They also study what causes (physiological, genetic, biochemical, trauma, external situations, etc.) neurological and psychiatric disorders as well as neurodevelopmental disorders in some people.
Before we further read on to what Neuroscientists do, let us get a brief understanding of a few terms and concepts associated with the Nervous system
Cognition is the process of knowing and recognizing the information that is sent to the brain with the help of experiences, thoughts and the senses. It is the mental activity that allows the brain to assess and perceive the information of an individual and involves various aspects of functioning and processes such as the formation of knowledge, memory, and judgment, reasoning, planning, problem-solving, etc.
Neurology/ neurological disorder: Neurology is the branch of medicine that deals with disorders of the nervous system i.e. it deals with the diagnosis and treatment of conditions and diseases involving the central and peripheral nervous system. Some of neurological disorders can be categorized according to the primary location affected, the primary type of dysfunction involved, or the primary type of cause.
Neurodevelopmental disorders: Neurodevelopmental disorders are due to the disturbance caused in the central nervous system. These disorders are due to abnormal brain development or by damage at an early age or due to other factors such as genetic inheritance, aging, and other diseases affecting mental processes (other diseases such as cardiovascular diseases leading to a cerebral attack) which affect emotion, learning ability, self-control and memory. Some of these are categorized as:
A neurodevelopmental disorder like Attention deficit hyperactivity disorder (ADHD), cerebral palsy, intellectual developmental disability etc. Some of the specific disorders are: Learning disorders like Dyslexia or Dyscalculia, Autism spectrum disorders such as Autistic Disorder, Movement disorders like Parkinson’s disease, essential tremors, Tourette’s syndrome, multiple sclerosis, etc., Communication or speech-language disorder like Dysgraphia, Aphasia, etc.; Genetic disorder like cystic fibrosis, Huntington’s disease, Down syndrome, etc.
But most importantly what do the Structure, function and physiology of the Nervous system mean?
In simple terms just like other systems in the body, the nervous system is a complex network of cells and nerves that carries messages to and from the brain and spinal cord to various other parts of the body and helps in the coordination of actions and sensory information. Any change in the environment which impacts the body is detected by the nervous system.
At the cellular level, the nervous system is defined by the presence of a special type of cells called:
- Neuron also called the nerve cell, and,
- Glial cells
These neurons or nerve cells are structured in such a way that it allows them to send signals to other cells. These signals are sent in the form of electrochemical waves which travel along the thin fiber-like structures called the axons. The axons then release chemicals called neurotransmitters at the junctions called synapses. (Synapses are structures that allow the neurons to pass an electrical signal to another neuron).
The glial cells are non-neuronal cells that provide support to neurons and hold them in place and supply nutrients to them. These glial cells also generate layers of a fatty substance called myelin that wraps around axons and provides electrical insulation which allows them to transmit action potentials much more rapidly and efficiently.
So, when a cell receives a signal, the neurons get excited or moderated and these connections between the neurons form the neural pathways, neural circuits and other larger networks that produce/generate an organism’s perception (understanding) of the world and control/determine its behavior.
The nervous system is divided into the central nervous system (CNS) and the peripheral nervous system (PNS). The central nervous system consists of two parts: the brain & the spinal cord. The brain is protected by the skull (the cranial cavity- space within the skull) and the spinal cord runs from the back of the brain. The function of the central nervous system is to send signals from one cell to others or from one part of the body to others and receive feedback and integrates the received information and coordinate and influences the activity of all parts of the body. And the peripheral nervous system (PNS) connects the CNS to the limbs and organs and serves as a relay between the brain and spinal cord and the rest of the body.
So why do we need to know about the basics of the nervous system at all?
Understand that the nervous system is the most important part of the body and all physical and mental activities are directly linked to the proper functioning of the nervous system. A neuroscientist’s job is to study, research, and investigate how and why humans/animals behave in a certain manner, what causes them to react in a definite way, what are the reasons some develop neurological disorders (explained above) and how these can be diagnosed. That is why it is important that you have a basic understanding of the nervous system and how it functions.
After understanding in brief the Nervous system; its functions and the disorders associated with it let us dig deeper into what exactly a neuroscientist does and what are some of the specialized areas they research in.
As a Neuroscientist, you would explore all the elements of the nervous system to understand how it is structured, how it functions, how it forms, how it breaks down and how it can be improved or changed. You will be concerned about all the facets of the nervous system including molecular, cellular, functional, and structural elements as well as evolutionary, medical and computational aspects.
As a Neuroscientist, you would research and analyze the nervous system in various branches of biology, psychology, computing, anatomy, and physiology among many others. For example, as a Behavioural Neuroscientist, you would study the biological explanation for human behavior. You would deal with questions like what causes normal and abnormal behavior, what causes reflexes and actions, and what triggers emotions etc.
As a Computational Neuroscientist, you would be studying and investigating how the human brain might perceive the information say while reading and why do you need to read it or what can you learn from it etc. You would be involved in processing, evaluating, and understanding how the electrical and chemical signals produced by the neurons are used in the brain to interpret and process information.
Neurolinguistics research and study how the human brain can process language and how the processing of spoken language is affected when a specific portion of the brain is damaged or non-functional. As a Neurolinguist, you would be dealing with questions like how the human brain combines words into structured sentences and these sentences derive meaning. How the brain is able to learn and store foreign languages and how does the human brain react to sound and what impact does it have on cognitive functions?
Popular Specialization in Neuroscience/Neurobiology Profession
Affective Neuroscientists are involved in the research and study of the neural mechanisms of emotion. The study examines how the brain creates emotional responses. These emotional responses are a psychological phenomenon that involves changes to the body in form of facial expressions, feeling states (subjective responsive) and the urge to act in a certain way. The study thus aims to understand how the structures and chemicals of the brain create emotions.
