...During the stage of adolescence, the brain is rapidly developing and has the capacity to grow connections that can strengthen certain neural pathways or can result in synaptic pruning. This is where extra neurons and connections are eliminated in order to increase the effectiveness of the neurological system. With the ability to learn this much, you will either use it or lose it. In the film, Inside the Teenage Brain, it explains that the cells and connections that are used will “survive and flourish” while the cells and connections that are not used will “wither and die”. The gray matter or thinking part of the brain, “continues to thicken throughout childhood as the brain cells grow extra connections, much like a tree growing extra branches,...

...A Look Inside the Brain-Housing Area Amanda Marie Cervantes Philosophy100 Seungbae Park, Ph.D. 18 September 2010 The human mind is quite a mysterious machine. While we can break down and examine every detail and trait of the human brain, we cannot dissect the human mind. We can only observe its distinctive traits and behaviors. Brain states and mental states go hand in hand but do not equal each other. If they were identical, there would not be the case of whether they relate, but more so of how the relationship between the two works. Brain states and mental states have different characteristics than one another. The mind resides inside of the brain, but it is not the actual brain itself. The only way to prove that the brain and the mind are one, would be to perform a successful lobotomy to test whether or not the receiving person would assimilate the previous owner’s mind, memories and traits and characteristics. If this were if at all possible, the receiving person would no longer have their original mind or memory of being their original self or anyone else for that matter. Brain state regulates and controls the body’s activities, receiving and decoding sensory impulses and communicating information to the muscles and body organs. The brain employs the ability to live and function. It is but an involuntary organ within the body, the nucleus, which controls all of the vital organs automatically by default. We cannot will the brain to keep the heart pumping...

...“Inside Drucker’s Brain” There are no second thoughts when it comes to Peter Drucker being credited, as “the leading founder of the field of management.” He was the first to describe management as more so a “practice, or discipline” as oppose to a science much like Frederick Taylor had assessed. Drucker was a man all about, “getting mangers to ask the right questions. To see beyond what they thought they knew, to look past yesterday so that they might get a glimpse of tomorrow.” He strongly believed in a life and management style that thrived on moving forward without looking back. Abandoning the ineffective or old to make room for the “highly promising and opportunistic new.” He was a brilliant man who to his grave claimed, he knew nothing about management from the “inside” since he had never upheld a management position. Also that he was immersed into the management world “totally by accident” and by “falling into it.” Nonetheless author Jeffrey A. Krames in his written biography titled “Inside Drucker’s Brain,” depicts the man who wrote the “handbook on management.” Not just through his achievements and contributions to the business world, but also through his efforts as a young man paving his way on his own terms, despite criticism or contrary beliefs. In this biography one takes away a sense of who Drucker was personally, professionally and intellectually. Krames includes Drucker’s most valuable principles, and strategies on how to manage a business or organization...

...BIOPSYCHOLOGY SEMINAR TOPIC: BLOOD BRAIN BARRIER, NEURAL CONDUCTION AND SYNAPTIC TRANSMISSION BLOOD-BRAIN BARRIER HISTORY: The blood brain barrier was discovered by the German scientist Paul Ehrlich who observed that intravenous injection of dyes into the body stained almost all organs except the brain. He believed that this was because the brain just didn't take up the dyes. Then in an experiment in 1913, Edwin Goldmann, who was one of Ehrlich's students, injected dye directly into the spinal fluid and observed that the brain did stain, but the rest of the body's organs did not. This demonstrated that there was some kind of compartmentalization between the bloodstream and the cerebrospinal fluid. Although, it had not yet been observed. It was the neurophysiologist Lina Stern who came up with the concept of the blood-brain barrier in 1921. She had been puzzled by the fact that medicines and serums injected into the body did not reach the brain, and came to the conclusion that there must be a special filter to protect the organ; she called it the "hematoencephalic barrier." WHAT IS BLOOD BRAIN BARRIER? A semipermeable membrane seperating the blood from the cerebrospinal fluid, and constituting a barrier to the passage of cells , particles and large molecules. It is a protective network of blood vessels and cells that filters blood flowing to the brain. Blood Brain Barrier is a membrane that controls the passage of substances from the blood into the central nervous system...

...The nucleus is an area inside the cell that contains the nucleic acids, protecting them by separating the genetic code from the cytoplasm, and keeps the cytoplasmic activity from interfering with any genetic material. Inside of the nucleus, proteins work together to copy parts of the deoxyribonucleic acids to the ribonucleic acids. This process of adding some of the DNA to the RNA is called transcription (Inside a Cell). The job of the nucleus is to coordinate all the activity of the cell, including growth, reproduction, protein production, and metabolization. Basically, the nucleus is the command center for all of the cell’s functions. Only advanced cells, which are scientifically named eukaryotes have nuclei. Unicellular prokaryotes don’t have a nucleus. Eukaryotes usually only have one nucleus, but slime molds and some types of algae can have multiple. The nucleus typically takes up a full tenth of the cell, making it one of the biggest organelles inside the cell. The average nucleus contains about 6 feet of DNA. That tiny sphere, only nanometers across, contains 6 feet of DNA. To add to that, DNA won’t properly function if it’s wound up into a tiny ball like string. It has to be combined with proteins and meticulously organized into the dense form of chromatin (The Cell Nucleus). To roll up those facts into a nice concluding wrap, I’ll just tell you this....

...Studying the brain can be a hard thing to accomplish. There are quite a few methods that our bio psychologist’s use to study the brain. As stated in Biopsychology 8 Ch5, “Some of the methods used to study the brain include: X-rays, contrast x-rays, magnetic resonance imaging (also known as MRI), positron emission tomography (also known as PET), and in my opinion the best way of studying the brain; functional MRI.” Unlike using just MRI to visualize the brain; functional MRI is a great way to study the activity of the brain, while being able to visualize the brain. When using just a magnetic response imaging machine to study the brain, the only great thing about using it is being able to visualize what is going on in an individual’s brain. For example; if someone were to have an appointment to look at their brain, to determine whether or not they have a tumor; this type of method would be a great method to use. The reason I say this is because an MRI machine is able to visualize if there is anything growing inside the brain. While an MRI may be a great method to use for this type of procedure; a functional MRI would be able to not only visualize what is growing in the brain; it would be able to show the doctor the activity of the tumor and other activity in the brain. As stated in Biopsychology 8 Ch5, “Functional MRI produce images representing the increase in oxygen flow in the blood to active areas in the brain.” Another great aspect of Functional MRI’s are that unlike other...

...Bennett The Brian The brain is consisting of three main sections. They are the forebrain, the midbrain and the hindbrain. These are connected to the central nervous system of the spinal cord (Pinel, 2011). The three sections of the brain can be subdivided into five main structures. The forebrain is where the two main structures reside; this includes the telencephalon and diencephalon which are located within the central nervous system. The midbrain is where the mesencephalon is located along with the hindbrain; the forebrain has the two final structures which are metencephalon and myelencephalon these main structures reside within the central nervous system of the brain (Pinel, 2011). The Myelencephalon, which is known as the medulla, that is located in the hindbrain, this, is the most position part of the brain. The medulla of the brain is the main structure that can carry signals throughout the entire body (Pinel, 2011). The medulla is responsible for the reticular that controls information within the brains central nervous system. The reticular information can be a complex network of the white and gray matter; this can smooth the transition between the descending and ascending signals of the central nervous system within the myelencephalon. The reticular information affects other functions of the body that includes sleep, movements, and arousal. The myelencephalon along with its reticular information can process structures of the brain that can become more serious...

...A hard blow to the head can shake the brain inside the skull, resulting in bruising, broken blood vessels, or nerve damage to the brain. When you take a hard hit to the head but there's no outward bleeding or opening in the skull, it could result in a closed brain injury. An open brain injury is when an object penetrates the skull and goes into the brain. A TBI can be mild or severe. A concussion is a mild TBI -- you should recover pretty quickly. A severe TBI can do enough damage to knock you unconscious for a longer period of time. It can even lead to a coma or death A concussion is caused by a jolt that shakes your brain back and forth inside your skull. Any hard hit to the head or body -- whether it's from a football tackle or a car accident -- can lead to a concussion. Although a concussion is considered a mild brain injury, it can leave lasting damage if you don't rest long enough to let your brain fully heal afterward. Just like you need to rest your ankle after a sprain, you need to rest your brain after a concussion. Get plenty of sleep to give your brain time to heal. Ease back into activities like school and work slowly when you start feeling better. Stay off the playing field until your doctor gives you the OK. Getting a second concussion before the first one has healed can slow your recovery and increase the risk for permanent...

...Brain Mapping Kaitlin Pollock Brain Mapping The brain controls thinking, moving, or any actions that are taken by a single person. Actually figuring out how the brain works is a very interesting topic. One way they do this is by using brain mapping. Brain mapping is the study of the brain using imaging, and they use these imaging machines to make a map of the neurons and synapses in our brain to figure out why people are the way they are. The history of brain mapping is important to understanding how far it has come today. There are many different machines that are used to take a look at the brain. When treating a patient there are different ways doctors can go about using brain mapping. This field just as any other field, is growing every day and never know what tomorrow could bring. Brain mapping has brought us many accomplishments in the medical field, understanding how it got there is the first step to the process. Taking a look at history can be boring at times, but when talking about the brain nothing is boring. In the early 1900’s is when humans first started to realize that our brain did a lot of the work compared to the rest of our bodies. People were shocked because how can that be, something you cannot see is the whole reason why you are the way you are. After this was discovered people wanted to take a look at this and start understanding it more. The first imaging machine ever used was the X-Ray machine in 1895. This machine is what gave the idea of using...

...Concussions are the most common type of brain injury and the least serious type of injury to the brain. Concussions are caused by a blow to the head that causes damage to the soft tissue to the brain. The brain is surrounded by a layer of spinal fluid inside the skull that acts like a cushion during normal movement. When you receive a hard hit, it causes the brain to move around inside the skull. The result is bruising to the brain and damage to the blood vessels and nerves inside the brain. This causes the brain to not be able to function normally. It can disturb the vision, resulting in sensitivity to light or blurred vision, and may cause the injured person to lose their balance. In short, the brain becomes confused and cannot function...

...X-RAY IMAGING SYSTEM BRAIN SCAN: BONE SCAN: SOFT TISSUE SCAN: CONCLUSION: X-ray imaging system is better for bony structures as it does not get absorbed in the bones, and the area where it does not absorb is highlighted with a whitish color on the photographic film, whereas x-rays gets absorbed in soft tissues so we get a blurred image in film. CT SCANNER BRAIN SCAN: BONE SCAN: SOFT TISSUE SCAN: CONCLUSION: A computed tomography (CT) scan uses X-rays to make detailed pictures of structures inside of the body. While much information can be obtained from a standard X-ray, a lot of detail about internal organs and other structures is not available. In computed tomography, the X-ray beam moves in a circle around the body. GAMMA CAMERA BRAIN SCAN: BONE SCAN: SOFT TISSUE SCAN: CONCLUSION: A gamma camera, also called a scintillation camera or Anger camera, is a device used to image gamma radiation emitting radioisotopes, a technique known as scintigraphy. Gamma camera gives best results for organs having more fluids. SPECT Scanner BRAIN SCAN: BONE SCAN: SOFT TISSUE SCAN: CONCLUSION: It is a technique that provides images similar to those obtained. It produce a 3-dimensional image of the body part being examined. Gives best result for organs containing more water content.

...stroke and how you can prevent it from happening. Body I. The two types of strokes that I will be talking about today are Hemorrhagic stroke and Ischemic stroke. A. A Hemorrhagic stroke is the rarer of the two types of strokes and accounts for about 13 percent of stroke cases which is what my grandma experienced. 1. It results from a weakened vessel that ruptures and bleeds into the surrounding brain. The blood accumulates and compresses the surrounding brain tissue. 2. The two types of hemorrhagic strokes are intracerebral hemorrhage or subarachnoid hemorrhage. B. Hemorrhagic stroke occurs when a weakened blood vessel ruptures. Two types of weakened blood vessels that usually cause hemorrhagic stroke are aneurysms and arteriovenous malformations or AVMs. 1. An aneurysm is a ballooning of a weakened region of a blood vessel. If left untreated, the aneurysm continues to weaken until it ruptures and bleeds into the brain. 2. A brain AVM is an abnormal tangle of blood vessels in your brain. 3. The buildup of the protein amyloid inside the arteries is also a common cause of hemorrhagic stroke, especially in older individuals. C. The other type of strokes is called Ischemic stroke and is the more common type...
