The Quantum Brain: Theory or Myth?
The study of neurobiology has long involved the actions and interactions among neurons and their synapses. Changes in concentrations of various ions carry impulses to and from the central nervous system and are responsible for all the information processed by the nervous system as a whole. This has been the prominent theory for many years, but, now, there is a new one to be reckoned with; the Quantum Brain Theory (QBT). Like many new theories, the QBT has merits and flaws. Many people are wholeheartedly sold on it; however, this vigor might be uncalled for. Nevertheless, this could prove to be a valid and surprisingly accurate theory of brain function.
One of the most convincing arguments of the QBT is its explanation of how reality is conceived by the brain. Classically, reality should always be changing, even by the slightest notion, and the brain should be aware of these changes as they occur. According to quantum mechanics, this would be impossible; there is no time during which something is changing. Therefore, the brain cannot be in a state of change, it must be in one state or another, there is no in between. The QBT states that our brain takes in reality one moment at a time, it is never in a state where it is observing something change. It observes reality before the change and then after the change and then fuses these two images together in order to make sense of them.
One question about the QBT comes when reality itself is considered; "why can't reality be a quantum system?" Well, there are a few explanations. One is that quantum systems are usually very small. Quantum mechanics cannot be used to explain the universe as a whole in all venues, however, can explain the movements of an electron, or the actions of a black hole. Another reason why reality cannot be explained by quantum mechanics is that quantum mechanics call for a holistic interpretation of the system. Reality, then, is much too large for all of it to be encompassed in one interpretation. Non-locality, another feature of quantum mechanics, prevents reality from being explained by quantum mechanics. Non-locality means that distance is not an issue in the effects of one part of a system on another. For example, curtains might not be blowing because your window is open and there is a wind, they might be blowing because somewhere in Russia, a woman is beating her rugs.

The concept about the split-brain cases is two hemisphere separate apart, where means the left side focus on the left side, the right side focus on the right side (Parfit 378). He thinks that the concept of the split-brain and the normal brain are both true. Parfit denies that there are no person involved, also the ego theory doesn’t exist. He believes that once the brain has split apart, it has two separate streams of consciousness (Parfit 378). So, he claims that instead of asking “what happened to the original self?,” he says there is no ‘self’ (Parfit 379). Even though there are different events happened at the same time, that is not equal to different egos. “There are not here two different possibilities, one of which be true. These are
“The Red Badge of Courage” was written by Stephen Crane in 1985 as a fictional tale of a soldier of the Civil War. With its accurate depictions, readers were led to believe that Crane had at one time been a soldier. This was however not the case. Crane has a unique way of using themes and symbols in “The Red badge of Courage” to relay a very realistic portrayal of war.

War is not meant to be glorified. War is not meant to look easy. Stephen Crane was one of the few authors during his era who realized this fantasy-like aura around war and battles and decided to do something about it. The Red Badge of Courage, by Stephen Crane, was inspired by Crane’s life and his desire to portray the realistic side of war.
For this reason, critical reactions to the The Red Badge of Courage in 1895 were mixed: some disapproved of Crane's use of the vernacular—the common slang of everyday folk and soldiers—and the impressionistic technique. Crane also experimented with psychological realism, and his venture into the realm of the human psyche radically changed the common perception of the novel in America. As he faces combat for the first time, Henry experiences an intense array of emotions: courage, anxiety, self-confidence, fear, and egotistic zeal. Interestingly enough, the naturalistic flavor of the work operates against this serf-important ego. The individual is not of primary importance, as is evidenced time and again in the words of Henry's mother, fellow soldiers, and officers. Henry is often referred to quite impersonally as "the youth." The men, untried and untested, are treated like scared animals against the backdrop of inimitable Nature and War. Crane also used color imagery, both vibrant and subtle, to describe war. He describes a skirmish as sounding like a "crimson roar," for example, and writes of war as "the red animal." Crane's sense of color pervades the work; note his description of the sky, which remains "fairy blue" during the day, as if to underscore the indifference of nature to the carnage taking place.
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 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.

The Red Badge of Courage, by it’s very title, is infested with color imagery and color symbols. While Crane uses color to describe, he also allows it to stand for whole concepts. Gray, for example, describes both the literal image of a dead soldier and Henry Fleming’s vision of the sleeping soldiers as corpses and comes to stand for the idea of death. In the same way, red describes both the soldiers’ physical wounds and Henry’s mental vision of battle. In the process, it gains a symbolic meaning which Crane will put an icon like the ‘red badge of courage’. Stephen Crane uses color in his descriptions of the physical and the non-physical and allows color to take on meanings ranging from the literal to the figurative.

Unlike so much literature preceding Crane’s work, his writings insist “that we live in a universe of vast and indifferent natural forces, not in a world of divine providence or a certain moral order” (Vanouse). His second novella, Red Badge of Courage, did immensely better in the public reception. This story of a young war soldier became “renowned for its perceived authenticity and realistic depictions of violent conflict”, even though Crane had never been in military combat upon its publication (Stephen Crane Biography”). He simply created the vivid images expressed in his novella through extensive research. This work, published abridged in newspapers in 1894, is often likened to an Impressionistic painting due to “his episodic narrative structure and his consistent use of color imagery” while others argue that it is solely symbolic imagery (“Stephen Crane”). With either view, however, the work is a great tribute to the genre of naturalism as it studies “human beings governed by their instincts and passions” while applying the scientific principles of objectivity and detachment (Campbell). Crane, a founding father of naturalism, discovers “the extraordinary and excessiveness in human nature” through the tragedy of war
Biology The brain consists of both neurons and glia cells. The neurons, which are cells housed in a cell body called a Soma, have branches which extend from them, referred to as dendrites. From these dendrites extend axons which send and receive impulses, ending at junction points called synapses. It is at these synapse points that the transfer of information takes place. At the heart of neuroplasticity is the idea of synaptic pruning.
The human body is divided into many different parts called organs. All of the parts are controlled by an organ called the brain, which is located in the head. The brain weighs about 2. 75 pounds, and has a whitish-pink appearance. The brain is made up of many cells, and is the control centre of the body. The brain flashes messages out to all the other parts of the body.
