No matter how fast you can finish or read a book, how fast can you read it with a given time? Think about this, each person has a different speed at how fast they can read out loud or speak and how their brain processes it, but how will the rate they read at change once they’re given a short amount, such as one minute to read an excerpt. Most importantly is how accurate will their reading be. The Brain and Its Function The brain is a complex system that houses the controls to your body ranging from your reaction, emotion, speech or language, development, memory, body functions, and much more. It’s created of a jelly like fat and protein weighing in about three pounds. It’s the body’s biggest organ and consists of over one hundred billion …show more content…
The Broca’s area was not just a matter of getting language out in a motor manner but it was more involved in the ability to deal with grammar itself, at least the more complex aspect of grammar. Apart from the Broca’s area, there‘s aphasia, the inability to speak, the inability to produce speech is Broca’s aphasia, or expressive aphasia. Someone with this kind of aphasia has little problem understanding speech but when trying to speak themselves are capable of only slow, laborious, and often slurred sequences of words (http://webspace.ship.edu). They usually don’t produce complete sentences, and seldom the use of regular grammatical endings such as –ed for the past tense, also tend to leave out small grammatical words (http://webspace.ship.edu). The Wernicke’s area is involved in the understanding of written and spoken language. Just like the Broca’s aphasia there’s the Wernicke’s aphasia is when you ask a person a question and they respond with a sentence that is more or less grammatical, but contains words that have little to do with the questions or, for the matter, with each other. People with this type of aphasia have difficulty naming things, often then responding with words that sound similar, or names of related thing, it’s as if they are having an absolutely hard time with their mental “dictionaries.”
We talked about Wernickes aphasia also known as fluent aphasia which causes comprehension difficulties. For example, people can talk in sentences that do not have any meaning and say words that don't make any sense. We also talked about Brocas aphasia also known as non-fluent aphasia which causes people to have a hard time with direction and prepositions. People with Brocas aphasia have trouble using connecting words for their sentences and understanding the order of the words in a...
The brain has four major lobes. The frontal lobe, the parietal lobe, the occipital lobe, and temporal lobe are responsible for all of the activities of the body, from seeing, hearing, tasting, to touching, moving, and even memory. After many years of debating, scientist presents what they called the localization issue, Garret explains how Fritsch and Hitzig studied dog with conforming observations, but the cases of Phineas Gage’s accident in 1848 and Paul Broca’s autopsy of a man brain in 1861 really grabbed the attention of an enthusiastic scientific community (Garret 2015 p.6)
Wernicke’s Aphasia is a communication disorder that affects one’s comprehension, therefore affecting language of both written and spoken language. Wernicke’s Aphasia is also known as fluent aphasia because individuals that have this disorder usually, for the most part, can typically express themselves using syntax and grammar but have a hard time doing it meaningfully through speech. Physiologically, when they speak, they do not realize that their speech is usually grammatically incorrect and lacks meaning behind it. People with this disorder have a hard time with auditory processing, fluently speaking, and poor repetition of what was previously said to them. Anatomically speaking, when one has Wernicke’s Aphasia this typically means that there
The cerebrum is located at the anterior-most part of the brain and is responsible for the combination of complex sensory and neural functions, as well as the initiation and coordination of voluntary activity in the body. It is the largest brain structure in humans and makes up two-thirds of the total mass of the brain (“Cerebrum Anatomy”, 2015). Its surface, a covering made up of grey matter usually 2-4mm thick, is called the cerebral cortex and is mainly made up of the cell bodies of neurons. The cerebral cortex is responsible for integrating sensory impulses, directing motor activity, and controlling higher intellectual functions. It is also responsible for the state of consciousness, which still remains a mystery to neurologists and the rest of the science community (Swenson, 2007).
Technology and the Brain As a college student, using the internet and technology is a daily task. Everything you need for your classes: schedules, homework, quizzes, and even tests are all online. The debate on technology and the brain suggests that technology may have an effect on the brain, effect multi-tasking, and cause addiction. Brain Activity
The left and right hemispheres of the brain are each divided into sections. Within each sections are lobes, controlling such processes as our visualization, our movement, and our personalities. For instance, the occipital lobe in the back of our brain is responsible for processing vision, and the frontal lobe behind our forehead controls cognition and personality. The lobes of the brain are split between the right and left hemispheres of the brain. This well-designed arrangement is for the lobes to function correctly, so the two hemispheres of the brain can communicate with one
The brain is the control center of the human body. It sends and receives millions of signals every second, day and night, in the form of hormones, nerve impulses, and chemical messengers. This exchange of information makes us move, eat, sleep, and think.
As the human body goes through different experiences, the brain grows, develops, and changes according to the environmental situations it has been exposed to. Some of these factors include drugs, stress, hormones, diets, and sensory stimuli. [1] Neuroplasticity can be defined as the ability of the nervous system to respond to natural and abnormal stimuli experienced by the human body. The nervous system then reorganizes the brain’s structure and changes some of its function to theoretically repair itself by forming new neurons. [2] Neuroplasticity can occur during and in response to many different situations that occur throughout life. Some examples of these situations are learning, diseases, and going through therapy after an injury.
The term ‘consciousness’ as it can be defined is the state of one being conscious or aware of one’s own being, existence, thoughts, feelings as well of his surroundings (Consciousness, 2014). It is often found that human beings tend to ignore the fact that consciousness is apparent in their existence. It has been assumed since early times that it is the brain that leads to production of consciousness in an individual. The brain in this case has largely been associated with the mind. While several studies have been conducted trying to determine the relation of consciousness with the brain, direct evidences were hard to find that could imply that brain and consciousness are identical. Rather it could be obtained that the operation of human consciousness can be beyond the brain or the body. Hence the two cannot be said to be identical (Dossey, 2009).
During this corse I lean multiple ways that the brain changes mentally as a person ages, such as cognitive development. There are many theories about how cognitive development occurs in children. Jean Piaget had a theory of cognitive development that included 3 different stages, the sensorimotor stage, the preoperational stage, and the concrete operational stage. The stages begin with learning though senses and actions, to have magical and egotistic thinking, to being able to think logically but not abstractly. Piaget also believed that people’s brains create schemas, almost like folders for the ideas of the brain, in order to organized they can understand them. When someone takes in new information,
The left and right hemispheres of the brain are each divided into sections. Within each sections are lobes, controlling such processes as our visualization, our movement, and our personalities.

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.
Most of the body’s functions such as, thinking, emotions, memories and so forth are controlled by the brain. It serves as a central nervous system in the human body. The mind is the intellect/consciousness that originates in the human brain and manifests itself in emotions, thoughts, perceptions and so forth. This means that the brain is the key interpreter of the mind’s content. Jackson and Nagel seem to resist identifying what we call “mental events” with brain events, for different reasons, while J.J.C. Smart takes the opposing view.
Wise (2014), discusses that within the twenty first century in which the efficient completion of tasks is essential, speed reading is extremely advantageous. Not only does speed reading allow for the quicker acquisition of knowledge, it has shown to influence the brains functionality. Thus, one displays enhanced memory abilities, a higher level of attention and focus as well as a heightened problem solving ability (Wise, 2014). Despite the advantages of an increased reading speed, there is a large and significant disadvantage (Bell, 2001). The danger of developing a rapid reading rate, is that one’s level of comprehension is severely compromised. Therefore, a speed reader would not acquire an adequate amount of information when reading swiftly. It is possible that this disadvantage will have a detrimental effect on the precise completion of various academic and recreational tasks (Bell,
One form of skepticism is the skepticism about the external world — the theory that we can never have any knowledge about the external world, even the existence of it; the theory also suggests that we can only know the internal world which is our own mind(Carr, lecture 8). For example, a skeptic may say “we don’t know if we have hands because what we see may be illusions” or “we don’t know if we are not brains in vats experiencing a huge hallucination”. Among many philosophers who attempt to defeat skepticism about the external world, Putnam argues that “we are brains in vats”(BIVs) is always self-falsifying because brains in vats do not satisfy the necessary condition for being able to refer to the
