Neuroscience
Hormones and the Nervous System
Of the many highly interesting features of the brain and the nervous system that are detailed in this chapter of the text, the one that I found most interesting is the relationship between the nervous system and the endocrine system, which controls the hormones secreted throughout the body. The initial comparison between hormones and neurotransmitters that the text makes initially helps to provide an immediate basic understanding of how the chemical messengers that hormones are might operate, but as the text goes on to describe the actions and direct effects of hormones it becomes clear that it is only in the simplest of sense that hormones are similar to neurotransmitters. Still, the influence that the endocrine system and the hormones it produces have on the nervous system are a...
I found it very telling that the pituitary gland is referred to as the "master gland" and yet is so directly under the control of the hypothalamus. This puts the "mastery" of the endocrine system in the hands (or the lobes) of the brain. The complex cascade of electrical and chemical messages that are sent through the body to…
Neuroscience and Human Development One of the most noticeable aspects of human beings involves the changes in shape, size, form, and function of the individual from a newly formed fetus to a fully grown adult. As the single most successful organism on Earth, human beings have developed, through millions of years of evolutionary adaptations, integrated yet malleable systems involving biological, physiological, emotional and intellectual components. This paper will review some of
The Hippocampus Region of the Brain and PTSD Prevention Abstract This paper examines the relationship between neuroscience and PTSD. In particular it looks at recent findings in neuroscience regarding PTSD onset and prevention. The latest research shows that brain volume is impacted by PTSD and that individuals afflicted with PTSD literally see a diminishment of brain volume in both hemispheres of the brain. Other findings show that individuals who are most susceptible
Neuroscience of Smell Human beings are bombarded in their daily lives with a variety of sensory data coming from a number of sensory systems in the human body. Many times the input of sensory data can cause a sensorimotor response, or an automatic action on the part of the human body in response to sensory input. In other words, the sight, smell, or sound of something can cause the body to
.....neuroscience is one of the most common scientific field of study that basically involves study of the nervous system. Most of the jobs in neuroscience involves dealing with some problems that do not necessarily involve working in the lab. An example of such jobs that interests me is neuropsychology, which is an area in neuroscience that focuses on the science of brain-behavior relationships. I find clinical neuropsychology as an interesting
Neuroscience is the study of brain mechanisms, how they function, how they are constructed, and how they relate to behavior (Kuhn & Koob, 2010). Neuroscience is a broad field that scrutinizes these brain mechanisms at all levels from the molecular and genetic levels all the way to the higher-order psychological processes and even to the understanding of clinical conditions. Because of its scope and its relevance to all aspects of
Reductionism in Cognitive Neuroscience Cognitive science is an interdisciplinary field encompassing various aspects of the study of the mind, including perception, reasoning, language, emotion and consciousness. Departing from the strictures of behaviorism, cognitive science permitted experimental psychologists to theorize beyond the limitations of observable behavior and functional relations between stimulus and response, and to posit internal mental representations as legitimate objects for scientific inquiry. With advances in neuroimaging technology, cognitive psychology
