Dreaming
The topic of sleep and dreaming is interesting to me because of the complex nature of the brain. It seems we know so much about human physiology, yet the brain is still mysterious. We know about neurochemicals, for instance, but do not really understand how memory is stored, accessed, or how dreaming affects our abilities during waking life. We know that a chemical upset, even minor, can make a huge difference in our state of consciousness, or our ability to perform in daily activities. Dreaming is fascinating to me because we know that the brain is a machine, and like any machine, it must be maintained (through nutrition) as well as rest and sleep. I find it personally interesting that dreams can be so vivid, unreal, frightening, pleasurable, and yet still mysterious.
Dreaming is part of sleep -- and a recurring stage in which our state of consciousness is reduced in varying degrees, our sensory activity is suspended, and we have a slowing of muscle reaction. Dreaming is a part of sleep and...
pp. 85-6 The brain can be understood in terms of its lobe-like structures, or it can be mapped out according to the regions that seem to dictate and influence certain behaviors and processes. The three major areas of the brain in this schema are the motor areas, the sensory areas, and the association areas, though in reality almost all human functions and behaviors involve interactions between these areas. Interestingly, large and
These individuals are good at solving complex problems quickly, allowing them to grasp the big picture even if they don't see the connections (Ali and Kor, 2006). Conclusion: In the end, there are differences in the right and left hemispheres of the brain, although some have been overly generalized in popular opinion. However, the differences that do exist do affect an individuals learning styles that are most effective. While two styles
Consciousness The term consciousness has been defined as "mental awareness of sensations, perceptions, memories, and feelings" (Brown, et al. 2003, p. 166). Most human beings live in three states of consciousness: waking, sleeping, and dreaming. Two other states of consciousness, meditation and drug-altered consciousness, can be induced. This essay will explore these five states further and will conclude with a discussion on their psychological relevance. Waking Most of our lives are spent
consciousness has been studied actively since the 1960s. Interestingly, Taylor (2003) notes, "Consciousness is a subtle phenomenon, which has so far resisted all attempts to understand it." Taylor's statement may be an exaggeration, as the author of this assigned reading goes on to discuss a number of facets of consciousness that have been well studied. These include biological rhythms, facets of waking consciousness, automatic vs. controlled processing, shifts in
Mind and the Brain There are several theories that have been proposed for explaining the relationship between one's mind and brain. If truth be told, it can be said that it is one of the most talked about philosophical fields. Mind vs. Brain Mind and brain are interrelated. For a majority of people, there is no difference between the two. Many scientists and philosophers hold the belief that the brain and the mind
Cognitive Effects of Brain Injury and Disease The care of patients with brain injury and diseases has improved substantially over the last thirty years. Nonetheless, the acute cognitive effects caused by brain injury are still a problem for the survivors. Such impairments are substantial contributors to functional disability after brain injury and reduce quality of life for affected persons and their families (Schultza, Cifub, McNameea, Nicholsb; Carneb, 2011). Accordingly, it is
