Brain Imaging

Imagine a football player is tackled and hits the back of his head. As a result, his brain has hit the back of the cranium, then the front.

While on patrol, I was parked in the entrance to Mansard's plaza, facing E Ridge Rd, monitoring traffic. A female in a silver pickup truck pulled into the lot and flagged me down. The female pointed towards a white and maroon Corvette traveling east on Ridge Rd and stated that she believes the driver may be intoxicated. I immediately pulled onto Ridge Rd and got behind the Corvette. As I was following the Corvette east on Ridge, another vehicle with a male driver pulled up to the side of me and shouted out the window, "That guy is drunk". I then observed the Corvette to weave from the outside lane to the center lane, without signaling. The vehicle then abruptly swerved back into the outside lane, without signaling. The vehicle then came to

The brain is one of the most complex organ in our bodies. To learn about the brain scientists use electrical stimulation. Electrical stimulation is the use of electrical probes to determine functions of the brain. Clinical observation of patients have also helped scientists learn more about the brain. Case studies of different patients such as Phineas Gage have helped to learn about the different functions of the brain and how they work together to perform complex activities.

MRI - Define: The MRI, or magnetic resonance imaging, is possibly the most familiar sounding to the general public. According to an article by Jason Levy from the National Library of Medicine, the MRI uses magnets and radio raves to get an image of the brains anatomy, this technique is where we get all those really cool sciencey images of the brain. As previously stated, the MRI is used to better understand anatomical structures and brain functions as they happen

A myth that many people believe is that humans only use ten percent of their brain. One reason why so main people believe this is because it has been pushed by many psychics or any paranormal pushers because if science can't explain it psychic powers can. Brain imaging such as PET scans, show that the majority of the brain is used at one point or another. Driving, for example, uses literally all of the brain to process everything that is being done.

There are many neurological diseases and the way the “regular checkup” goes will be determined by the type of disease they have. For instance a patient with a nonfatal diagnosis of Multiple sclerosis can have a neurological checkup; the physician should recap the patients’ health history and determine what brought them in. Ask if anything has changed since the last checkup. Assess mental status, obtain vital signs and ask if patient is in pain or if they have a feeling of numbness or tingling anywhere.

Brains are very important as you may know, that is why I will be giving you an insight on how to protect your brain and get information on how to know if you or a loved one could be having a brain hemorrhage. Imaging of the brain has become very significant to finding pathologies and catching life threatening brain hemorrhages. There are two types of hemorrhagic strokes and they are subarachnoid or intracerebral which means ‘within the brain’. These strokes can occur when a weakened blood vessel ruptures. Any one of these vessels can rupture which would cause bleeding into the brain, this is the effect of severe pressure and will lead to serious outcomes. This is why imaging of the brain is very important if you or a loved one is having symptoms of a brain hemorrhage. This could essentially cause injuries to the brain and could lead to symptoms of a stroke. Imaging is crucial to hemorrhages because how else would you be able to see what is going on in there! Computed tomography is the first step in the process of detecting a brain hemorrhage. There are other imaging modalities that can further see what is going on and are more detailed, they are just a little bit more invasive than the CT which is done at first. It is very important to catch the hemorrhage early because it could potentially cause permanent brain damage or death. According to the article “Guidelines for the Management of Spontaneous Intracerebral Hemorrhage”, written by Joseph P. Broderick along with other

Medical imaging, how interesting is that, it’s a tool that helps go into depth about how the brain is functioning, and how it has developed. Medical imaging has many great and useful resources. Imagine how great it will be if medical imaging would develop even more than we have it today, we can find many new ways of discovering---BEYOND what we have already discovered. According to Kunio Doi in his article titled, “Diagnostic Imaging over the Last 50 years: Research and Development in the Medical Imaging Science and Technology,” indicates “In the last 50 years imaging has grown to a high state of high level;” as a matter of fact technology we have today can become an even more successful resource in a matter of years.

Neuroimaging can be a useful tool in detecting physical abnormalities in the brain. Most people with a severe brain injury will show an abnormality in a neuro-imaging test. These scans cannot detect all types of brain injuries, so it is possible to have a severe brain injury and be in a coma even though the scan results are normal.

Brain-imaging tools, such as functional magnetic resonance imaging (fMRI), allow researchers to have a close look at brain structures and activities.

In class, we also learnt about how important cerebrospinal fluid is because it helps to keep the brain afloat as the weight of the unsuspended brain would damage neurons (buoyancy), protects the brain from injury to some extent (protection), removes waste products associated with metabolic activity (chemical stability), and controls blood pressure in the brain (prevention of ischemia). The article also discusses MRI (anatomical imaging) which is a topic we have recently discussed in class and we learned about how an MRI uses a large magnet to align all the protons in the sample and produce an

Title: Evaluate experimental and brain-imaging techniques and consider what they tell us about the brain and cognitive behaviour in typical and atypical individuals.

2. Functional brain mapping (scanning a person's brain while he or she is performing a certain physical task such as squeezing a ball, or looking at a particular type of picture) is helping researchers better understand how the brain works.

With the advancement in technology, neuroimaging has led to the discovery of male brains containing a greater amount of white matter, while female brains contain more gray matter (Gur et al., 1999). Sun et al. (2015) collected imaging data to track the progress of brain network topology over a five-year period and compared the results between gender differences. Participants in the study included 43 males ranging from ages 22-53, and 28 females from ages 21-59. Only those having no brain disorders, mental illnesses, substance abuse, or first-degree family members with mental illnesses were included in the research. Twenty-eight subjects completed the study and received scans over 5 years. The results supported findings from previous

During the early 1970’s something called Computed Tomography (CT) Scanning was introduced into medicine. The CT scans were able to provide the first clear image of the brain and brain tumors. This was done by using X-Rays which provided doctors with images of a section or “slice” of the brain. In the following decades, CT Scanning becomes more and more refined and is now also being paired with other imaging techniques such as Magnetic Resonance Imaging (MRI) which was invented by Damadian in 1977 (Filler, 2009).
