Extract of sample "Obtaining Structural Images of the Living Human Brain"

Describe and compare the various techniques commonly used for obtaining structural images of the living human brain. One technique used to obtain structural images of the living human brain is called a Computerized Tomography (CT) scan. This type of brain scan uses a series of x-rays from different angles to create images of the brain. CT scans can show a 3D view of both the bone and soft tissue of a brain at the same time.
Magnetic Resonance Imaging (MRI) can also be used to obtain structural images of the living human brain. MRI uses magnetic fields to provide high definition images of the brain. Unlike CT scans, MRI provides greater image detail and can show both the coronal and sagittal areas of the brain.
Also, a Diffusion-tensor MRI can detect the direction of fibers in the brain which can be used to create connectivity graphs of the brain.
The modern model of sensory system organization features three important principles. Name them and explain them. Draw a representation of the modern model.
One important principle of the modern model of organization is that the sensory system is parallel. This means that information moves between different structures along multiple pathways simultaneously.
Another important principle of the modern model is that the system is functionally segregated. This means that structures in the system are comprised of different parts that specialize in different kinds of analysis.
A third important principle of the modern model is that the system is organized hierarchically, which means that information flows through brain structures in a specific order based on how functionally and nueroanatomically complex they are.
The chemical senses are unique in several ways. Describe and discuss two ways in which either the gustatory or olfactory systems is different from other sensory systems.
One way the olfactory system is different from other systems is that there is no thalamic relay when sensory activity is transferred to the olfactory bulb. This means that the olfactory system bypasses the thalamus; which controls the flow of information to the cortex.
Another way the olfactory system is different is that the receptor neurons of the system are continuously replaced through mitotic division. This continual replacement occurs because olfactory neurons are exposed directly to the environment; therefore the neurons have a very high vulnerability and need to be replaced continuously.
Discuss the two effects of damage to the posterior parietal cortex.
One effect of damage to the posterior parietal cortex is known as Apraxia, which usually occurs as a result of damage to the left side of the cortex. Apraxia inhibits voluntary action. One example would be not being able to lift your arm on command.
Another effect of this type of damage is called Contralateral Neglect. This damage usually occurs on the right side of the cortex and makes the person unable to respond to stimuli on the opposite side where the damage occurs. People with this type of damage often ignore putting make-up on or shaving one side of their face; usually the left side.
Discuss the concept of central sensorimotor programs. Describe and discuss three of their important features.
Central sensorimotor programs are programs of activity that are programmed into the sensorimotor system.
One feature of central sensorimotor programs is that all but the highest levels of the sensorimotor system have programs built into them and basal ganglia and cerebellum coordinate these programs.
Another feature is called motor equivalence. This means that programs are stored at a higher level than the muscle level so that a particular movement can be achieved using different muscles and in different ways.
A third feature is that the system achieves greater speed by shifting the program controls to lower levels. This frees up higher levels of the system to achieve more complex tasks. Read More

...neurons5, 6. In the process of undergoing continuous learning, the neurons in the brain expands by growing more “axon” and “dendrites” which are directly responsible in linking the neuron with other neurons7, 8. Coon and Mitterer (2010, p. 48) mentioned that “each of the billions of nerve cells in the brain is linked to thousands of others”9. Based on this theory, one can easily conclude that the human brain is so powerful and is very much capable of acquiring, consolidating, and retrieving unlimited information for a lifetime thinking process10. Specifically the connections between the brain cells are quite complex. For instance, a tiny...

Human Anatomy Structural Levels of Organization

...?Essay The human body can be structurally ified into six levels. It begins with the simplest chemical ification and ends with the organismal level. The first chemical level includes the basic unit of the cell, the atom, which in turn combine to form molecules such as water and proteins. The molecules combine to form organelles which constitute the components of cells. These cells constitute the cellular level of classification and while all cells perform certain common functions, they may vary in size and shape based on their other specific functions within the body. These cells appear single in simpler creatures and appear grouped in multi-cellular organisms. A group of cells constitute the tissue levels...

Structural Fire and Structural Failures Full Structural Fires and Structural Failures Introduction Our ever changing living standards and development of our infrastructure is continuously updated to provide us with better living conditions. Our economy depends on the infrastructure; however, as our cities expand, the infrastructure becomes overloaded and in turn, susceptible to basic dangers as fire or even structural failures. In between 2007 and 2011, fire departments in the United States alone received an average of 366,600 calls per year for home structural fires (Ahrens, 2013, p.1). These fires...

Human Brain and Computer

...Human Brain Verses Computer Psychologist and other scientists have compared the brain to different inventions all through the history. As computers became more widespread in the 1950s and 1960s, scientists began to highlight the similarities between brains and computers. For instance, the brain has been said to be like a water clock and a telephone switchboard in earlier days. Today, the brain is compared to a computer. This metaphor is used by some people to say that the computer is better than the brain whereas others say that the brain is better than the computer. Indeed both brain and...

Human Cognition and the Brain among the initial proof recommending that serious injury to the frontal lobes of the human brain could change elements of attitudes and behavior and will have an impact on the communicative abilities. Prior to this case the frontal lobes were commonly perceived to possess very minimal responsibilities in attitudes (Fleischman, 2004). With respect to current medical research, a serious injury to the brain especially in the frontal area by an object that has dimensions of more than an inch in diameter and has a weight of more than ten pounds, would definitely make living impossible for the person, since this would mean a lethal destruction to essential...

In fact, what is essential in every company is the relationship between the distributors and the company (Kennedy, 2006). When it comes to brand strategy and large companies, the power of brand image has a significant influence on the performance of their distribution channels. L’Oreal, the French world leader in cosmetics, is one of the best cases of the channel and brand image consistency. This has led to the company’s worldwide success. Hence, it is vital for firms to have a consistency between their channel...

Brain Food in Early Human Ancestors Diet

...The article provides a clue about how the human brain could have evolved over the years with the discovery of the food consumed by our early ancestors from excavated animal bones and stone tools. The project, which is funded by the National Science Foundation and a collaborative effort of several institutions, provides evidence to the consumption of aquatic brain foods such as fishes, turtles and crocodiles by our ancestors which are rich sources of polyunsaturated fatty acids and docosahexaenoic acid. Studies have shown that these fatty acids are vital for brain growth and development. Hence these foods consumed by our ancestors could have helped increase the size and...
