Enteric nervous system

Because people operate at different conscious levels according to their task or thoughts, many different results can occur from the experiment. A large and truly random group of test subjects would create the best results for this test. Tasks or thought triggers chosen to specifically target one area of the brain could be performed at different states of consciousness such as: different levels of awakeness, during the use of a mind-altering drug, or at normal conditions. Recording observations…

best classified as nematodes that take the form of long cylindrical bodies with tapering ends that survive by feeding on bacterium and are free-living in soil (Edgley, 2015). C. elegans possesses a genome that presents a simplified prototypical nervous system that is particularly easy to observe at a molecular, cellular, and organismal level. This makes them an ideal model organism because they share the same characteristics necessary in the human body (Schafer, 2005). Chemotaxis refers to…

Avascular necrosis is when your bone tissue collapses and breaks down and eventually dies due to the lack of blood supply that it gets. The Age group that the disease mostly common in is 41-60. How can you tell you have this ? We will analyze a lot of the key factors in the disease. What kind of symptoms you have during. Do people who have diabetes or cholesterol are more prone to this disease? A Lot of questions will be answered in this brief presentation. Age wise this disease is focused on…

Introduction: Age related change is one of the most common causes of vision loss around the world, affecting between 30 to 50 million people worldwide. As suggestive of the name, age-related macular degeneration (AMD) is most prevalent in adults over the age of 60. Of the cases of AMD, about 90 percent are dry AMD for which no effective treatment exists [1]. The retina is the nerve tissue lining the inside of the eye which begins the conversion of light into vision. The macula,…

In the article, “Is Google Making Us Stupid?” by Nicholas Carr says that his current troubles with concentrating while reading books and long articles might be because of investing a considerable measure of energy in the Internet. He believes that the customary internet utilization may have the impact of decreasing the limit with concentration and contemplation. Carr goes ahead and gives an exceptionally very much examined record of how contents on the web should make the browsing experience…

Amyotrophic Lateral Sclerosis (ALS) is a neurodegenerative disease that involves motor neurons in the brain and spinal cord. ALS is considered to be one of the most common progressive neurological diseases, affecting approximately 20,000 individuals in the United States in a given year (Fried-Oken et al., 2006). Etiology of ALS remains unknown; however, there appears to be an existing genetic component associated with this disease. Changes in speech are first seen in patients with bulbar onset…

Have you ever found yourself staring at a math problem that seems impossible to solve? Do you wish there were an easy way to help your brain focus? Aromatherapy might be your answer. This experiment will test if the aromatherapy scents of jasmine and sandalwood help the brain’s speed and accuracy in completing a puzzle. The sense of smell begins in the back of the nose where millions of sensory neurons lie on a tissue called the the olfactory epithelium. As soon as an odor molecule binds to a…

The basal ganglia plays a vital role in the way movement happens and when dopamine does not follow the path that it is suppose to, it hinders body movement. Parkinson’s disease is often known as PD and it is a progressive neurological condition, which means the sickness and symptoms get more severe as time goes on (Noble, 2007). Out of all the neurodegenerative disorders, PD is the second most common one (Noble, 2007). It happens amongst 1% of the population older than sixty years. (Samii, 2004)…

Susan’s main areas of difficulty involve motor speech, which affects her intelligibility. Particularly relating to the larynx, use of the tongue in speech and coordination of the lips and palate. This indicates that Susan is likely experiencing mixed spastic-ataxic dysarthria due to lesions on the upper motor neurone pathway (Wilkinson and Lennox 2005) in the corticobulbar tract which innervates the cranial nerves and the cerebellum (Bethoux et al 2013). Lesions on the upper motor neurone…

Explanation of EMG signals EMG stands for electromyography. Muscle fibres generate tiny electrical currents prior to the production of muscle force. These currents are generated by the exchange of ions across muscle fibres membranes, a part of the signalling process for the muscle fibres to contract. EMG is the signal made, it can be measured by applying conductive elements or electrodes to the skin surface, or invasively with the muscle. When using EMG, tiny devices named electrodes are used…
