Consciousness poses the most baffling challenges in scientific realm of the mind. There’s nothing with which we share an intimate relation than conscious experience, but there’s nothing so strenuous or demanding to explain. Perhaps no other aspect of mind is more puzzling than this mystifying experience that we encounter in our every day life. There’s a widespread disparity amongst individuals regarding the existence of this entity. Some might argue that consciousness is not more than a foolish idea

Alzheimer’s disease is a degenerative disease that attacks and ultimately destroys brain cells. Without these cells functioning properly, every aspect of a person’s life is adversely affected until they are no longer able to care for themselves. Despite years of research and the large amount of money that has gone into the study of this disease and its effects, there is much that remains a mystery in regards to Alzheimer’s disease. While great strides have been made towards a cause and ultimately

Outline Introduction a. i. There are people around the world that still believe that Alzheimer’s is a normal part of aging and that it isn’t fatal. ii. Research shows that Alzheimer’s disease causes changes in the brain for decades prior to the first symptoms become visible, so even people who seem free of the disease today might be at risk. iii. Alzheimer 's disease has no survivors. It 's a disease that destroys your brain cells and causes it to malfunction, change memory

The development of the cortex is a delicate balance between proliferation, differentiation and migration of neural progenitors (NPs). Throughout developmental process, various cellular mechanisms ensure that NPs are differentiating into the correct cell subtypes, migrating to their correct regions, and forming the correct cortical and sub-cortical layers. The cortex is comprised of both excitatory and inhibitory neurons, which interact within neuronal circuits to mediate cortical functions. Though

The brain processes sensory input of different modalities simultaneously in cortical areas. Sensory information of different modalities is either processed independently before being integrated to provide an overall picture of our surroundings, or cross-modal interaction occurs before integration. We compared visual evoked potentials (VEPs) evoked when attention is directed toward either visual or auditory stimuli and found no difference in mean P100 when attention was directed toward visual stimuli

Writing is not a monotonous task assigned in school, despite popular belief. Writing is recording a thought, fact or fiction, pretty or disturbing, or both. Whatever the definition of writing is to an individual person, it is a skill. Writing as a skill has value to the person perfecting their skill and society. Society has benefited from the innovations that would not have been created without writing, as well as the innovation of the human brain caused by our ancestor’s scribblings. Writing is

Structures of the Brain The Brain Stem The brain stem or the medulla is the closest to the spinal cord. The brainstem is responsible for most of the human bodily functions. The brain stem is critical for human survival and normal human functions. The brain stem is also responsible for information of pain and touch from the head and neck; it is also responsible for the inputs from the face and the mouth. Reticular formation is a group of neurons, nuclei, that are important for sleep and wakefulness

I read the article, “Secrets of the Brain”, found in the February 2014 issue of National Geographic written by Carl Zimmer. I chose this subject because I have been fascinated with the brain and how it works. The research of the brain has been ongoing for many centuries now. The history in this article is interesting. It explained how scientists used to understand the brain and its inner workings. For example, “in the ancient world physicians believed that the brain was made of phlegm. Aristotle

“That step wasn’t there before!” and, “I didn’t trip. I was…. dancing,” are a few excuses that people may use when they make a mistake. It is not uncommon to hear people create these excuses to cover their embarrassment of missing the last step on the stairs, or for tripping over a crack in the sidewalk. Although some of these alibis may seem like reasonable answers, they are almost always incorrect. The proper explanation for events, such as the examples mentioned, is based on reaction time. The

Growing up in poverty has a significant effect on the brain. While poverty affects many aspects of the brain processing, spending patterns are impacted which affects quality of life. Occasionally, those in poverty make it out. Despite gaining a higher socioeconomic class, quality of life can still be influenced by the impact of poverty. This is because those who grew up in poverty continue their impulsive spending habits when they move into the middle-class because poverty leaves an enduring impression
