Neuroscience is a branch of science that studies the ways the nervous system and the brain work, develop, etc. neuroscience tries to understand the appearance, growth and development of neurons, along with their connections.
First, what is the nervous system? The nervous system is the connection between nerves and cells that take a message to the brain and the spinal cord. This system is divided into the central nervous system (CNS), which contains the brain and the spinal cord, and the peripheral nervous system (PNS), which consists on sensory and motor neurons. The PNS has its own nerves that connect to the CNS sensory organs, blood vessels, etc. This part of the system is all around the body, except for the center 8 in the spinal cord and brain). The CNS, as before said, consists of the spinal cord and the brain, it is

Affective neuroscience: studies how neurons are related to the emotions.
2. Behavioral neuroscience: studies how the brain affects the behavior.
3. Cellular neuroscience: studies neurons.
4. Clinical neuroscience: disorders in the nervous system, such as a stoke, when a part of the brain dies; transient ischemic attack, which is kind of a mini-stoke, which is caused by a temporary blockage; an hematoma, that is the swelling of blood between the tissues, etc.
5. Computational neuroscience: it uses computers to simulate the brain´s functions, and graphically see how it works.
6. Paleoneurology: the study of the brain with fossils. It studies their shape, distribution, etc, and it is linked with computational neuroscience, for the recreation of the brain.
7. Social neuroscience: studies how biological systems affect behavior around people (social disorders).
8. Neurolinguistics: studies the mechanism of the brain when learning a new language, talking or writing; or the disorders that come along with these
The human nervous system is divided into two parts, the central nervous system and the peripheral nervous system. The central nervous system, CNS, is just the brain and spinal cord. The peripheral nervous system, PNS, includes the nerves and neurons that extend outwards from the CNS, to transmit information to your limbs and organs, for example. Communication between your cells is extremely important, neurons are the messengers that relay information to and from your brain. Nerve cells generate electrical signals to transmit information.
Neuroscience is about how the brain develops and functions. how it influences cognitive function and behaviour. About how the nervous system functions how it develops, and what it does. (Neuroscience, 2017) Neuroscientists have shown that the brain is affected by environmental conditions throughout the entire process of development, even prior to birth. This includes the type of nourishment, care, surroundings and stimulation the foetus or infant receives.(moodle,2017)
Hypothetically speaking, if patients asked their neurologists to explain what the nervous system is, how would typical neurologists respond to such a question? For the most part, patients ' question on what is the nervous system maybe a simple question for neurologists. In this instance, neurologists possibly explain to patients that the nervous System serves as a communication network that operates and coordinates the body 's activities. Operating and coordinating the body 's activities includes the nervous system to monitor thoughts, learning processes, body temperature, and altering the heart rate-- To name a few of the nervous system 's responsibilities. During the topic of discussion on the nervous system, patients asked their neurologists
Almost all animals have a nervous system. Neurons bundle together to form nerves. The purpose of the nervous system is to coordinate all activities of the body, and enables the body to respond and adapt to changes both inside and outside. The central nervous and the peripheral nervous systems are very similar but different at the same time. The CNS is made up of the brain and spinal cord and functions mainly to process information and determine the appropriate responses. The central nervous system receives sensory information, figures out a response, and initiates a motor response if appropriate. The CNS is protected by the skull, vertebral column, and a membrane. The spinal cord provides communication between the brain and the peripheral nerves
The nervous system is the most complex part of the body, as they govern our thoughts, feelings, and bodily functions. It is an important factor in science because it can lead to new discoveries for cures or diseases. The studies of the nervous system helped lower death rates from heart disease, stroke, accidents, etc. The nervous system is a network of neurons (nerve cells that sends information to the brain to be analyzed.
Neurobiology is a theory that deals with the brain and your nerves. It determines if you are a left or right brain person. One of the theorists is named Roger Sperry. He was a very big neurobiologist. A disease that deals with this theory is ADD/ADHD.
This paper involves how the brain and neurons works. The target is to display the brain and neurons behavior by sending signals. The nervous system that sends it like a text message. This becomes clear on how we exam in the brain. The techniques show how the brain create in order for the nerves about 100 billion cells. Neurons in the brain may be the only fractions of an inch in length. How powerful the brain could be while controlling everything around in. When it’s sending it signals to different places, and the neurons have three types: afferent neurons, efferent neurons, and the interneurons. In humans we see the old part of emotions which we create memories plus our brain controls heart beating, and breathing. The cortex helps us do outside of the brain touch, feel, smell, and see. It’s also our human thinking cap which we plan our day or when we have to do something that particular day. Our neurons are like pin head. It’s important that we know how our brain and neurons play a big part in our body. There the one’s that control our motions, the way we see things. Each neuron has a job to communicate with other neurons by the brain working network among each cell. Neurons are almost like a forest where they sending chemical signals. Neurons link up but they don’t actually touch each other. The synapses separates there branches. They released 50 different neurons.
Neuropsychology is a branch of general psychology that is concerned with how the brain and the rest of the nervous system influence cognition and behavior. Professionals in this branch make it a goal to understand of how the brain influences cognitive functions and behavior. In fact, modern neuropsychology has roots that began in the 19th century. During this time, some of the first neuropsychologists studied animals and humans with brain and nervous system injuries. The significance of neuropsychology is subject to urgent brain trauma, which could cause complete loss of functionality of the body. The study of neuropsychology helps doctors understand how brain malfunctions occur.
The software structure begins in quantum physics; the branch of physics relating to the very small (protons, electrons etc.). It then transforms from quantum physics to nuclear physics which is the research is focused on understanding the matter composed of quarks and gluons, which makes up 99% of the mass of the universe. Next would be chemistry; the study of matter, and all matter is made up of atoms. It teaches about elements , atomic number and mass, isotopes, moles and compounds. Which then births organic biology; a molecule has a carbon backbone, with some hydrogen thrown in for good measure. Living creatures are made of various kinds of organic compounds. This leads us to biochemistry; the study of chemical processes within and relating to living organisms. While moving forward the chemistry is no longer needed, leaving you with biology; the study of life and living organisms, including their structure, function, growth, evolution, distribution, and taxonomy. Which brings you into Neurology; the branch of medicine or biology that deals with the anatomy, functions, and organic disorders of nerves and the nervous system. The root word of neurology is neuro- which means relating to nerve. Nerves are bundles of fiber that transmits impulses of sensation- perception or awareness of stimuli through the senses.-to the brain and spinal cord; this is where consciousness begins. Having of
The brain and spinal cord make up the central nervous system. The brain doesn't just control your organs, but also can think and remember. That part of the brain is called the mind.
In this paper the writer is going to present an overview of the field of neurolinguistics which is the study of the mental faculties involved in the perception, production, and acquisition of language. In other words, the neurobiological factors that enable humans to acquire, use, comprehend and produce language.
The nervous system’s main function is to coordinate all of the activities in the body. The main organs are the cerebellum, which controls and coordinates movement. The cerebrum, is the center for conscious thought, learning, and memory. The last main organ is the brain stem. The brain stem keeps the automatic systems in your body working. Problems of the nervous system include, epilepsy, Alzheimer’s, and multiple sclerosis. You can care for your nervous system by wearing a seatbelt, wearing a helmet, and by not using drugs or alcohol. Something very confusing about the nervous system is that the left side of human brain controls the right side of the body and the right side of the brain controls the left side of the body!
The nervous system is composed of all nerve tissue in the body. This organ system forms a communication and coordination network between all parts of the body. It plays a major role in everyday activities such as breathing, walking even blinking. It is made up of nerve tissues to receive and transmit stimuli to nervous centers and initiate response. Neurons are nerve cells that transmit signals from one location of the body to another. With damage to the nervous system the body would not be able to function properly. The body has to be well taken care of in order to insure proper regulation. The two anatomical divisions that work hand in hand to help regulate the nervous system are the central and peripheral nervous system. According to the Campbell’s seventh edition biology book the nervous system is the most intricately organized data processing system on earth. It is a complex collection of nerves and specialized cells.
It is thus concerned with brain cells, brain structures and components, brain chemistry, and how all this leads to speech and action. It is also important to understand how we take in information from our five senses.
With a multidisciplinary approach, neurolinguistics also uses neurophysiological techniques to ask questions about the neural implementation of the language such as;
