Myelin

⦁ Oligodendrocytes-Have an essential role in making myelin active during injuries or events that include progressive regeneration. ⦁ Human accelerated Regions (HARs)- Known as gene switches, HARs are regions of our genome that control gene regulation. ⦁ Jumping Genes in brain defects- Jumping Genes or transposons…

Every day, thousands of people are faced with various diseases and conditions that affect them or their loved ones with life changing disabilities. Disabilities that are of a neurological nature usually are those that are the most life altering or threatening disorders and conditions. Charcot-Marie-Tooth Disease is one of these conditions. Even though Charcot-Marie Tooth (CMT) is a genetic disease which affects the sensory and motor nerves, the patient can survive and be treated for this…

Hoffman-La Roche, Inc. (referred to as Roche) is an international pharmaceutical company. His goal, a goal upheld by the company today, was to invent and produce new superior drugs and to distribute them internationally. In 1982, Roche introduced a prescription drug to the public unlike anything they had ever seen before. The drug they put on the market was FDA approved Accutane (also known as isotretinoin). This medication was to aid those who suffered from severe acne, finally offering a…

1. Neurogenesis and memory 1.1. Neurogenesis in the hippocampus The hippocampus is a brain region that responsible for learning, memory and mood. One of the important reasons for memory and mood dysfunction is the dentate gyrus (DG) reduction [12, 13]. The subventricular zone (SVZ) and the subgranular zone (SGZ) of neural progenitor cells generated neurons and glia in adulthood and during adulthood [14]. Neurogenesis also have a role in mood regulation; the dorsal hippocampus is an…

Neuropathic pain whether based on an injury or a result of a form of dysfunction from the nervous system is still a condition which better treatment options are still being researched. Neuropathic pain can even be divided further into peripheral and central neuropathic pain. While peripheral pain may result from a disease, a more central neuropathic pain may result from damage to brain or spinal cord. [] Despite numerous medications in the market and therapy treatments which patients endure,…

Michael Phelps, Serena Williams, Usain Bolt and Louis Zamperini have one thing in common: a unique nervous system. What makes an olympic athlete’s brain anatomy different from a regular athlete? What changes take place in their brain and its connecting peripheral nerves? And can anyone become an olympic athlete? The human body is capable of making changes to itself to adapt to different environments and specific tasks. Not only do the muscles in our body change but also our brain and certain…

Most of us grew up hearing commercials stating, this is your brain, this is your brain on drugs. The commercial used an egg frying in a pan as the metaphor of drugs frying our brains. Does that hold true with marijuana? A great debate today is whether or not medical marijuana should be legalized. The controversy surrounding the legalization of marijuana debates the drug effectiveness vs. safety and regulation. My belief is that marijuana can have many positive effects on a disease process where…

Study of the brain is significant in gaining insights on its structural and functional design and mechanisms which help explain the cause of various existing neurological and psychiatric diseases (Kotter, 2001). Consequently, the histological study of the nervous system and its components which underlies the understanding of the brain forms the basis and foundation of neuroscientific research (Annese, 2012). Important components of the nervous system include the spinal cord which consists of…

The idea that one day we will all die is inevitable. Most individuals do not think about the future and death. We shrug this thought from our minds because we cannot predict the future. In some cases, some will say that they are young and that the idea of death, now, is preposterous. For others, that day may seem to be looming closer and closer as they advance into their 70s. Despite how you may feel about death, we can all concur that this will happen to all of us, and how we approach death,…
