The Human Brain
In our Psychology class we watched a film from the Discovery Channel about our Central Nervous System, particularly, The Brain - its parts, functions and how it respond to the environment. The brain is the seat of our mental faculties. It assumes vital functions by influencing heart rate, body temperature, breathing, etc., as well as performing the so-called “higher functions”, such as language, reasoning and consciousness. This organ includes two hemispheres, the left and the right hemispheres, with each further divided into four lobes: The occipital, parietal, temporal and frontal. Even though it plays a fundamental role, the brain remains one single part of a whole organism. It is continually changing – developing – throughout life. The brain is active throughout every day, even as we sleep, but we rarely, if ever, stop to consider that our thoughts, actions, and perceptions are the outcome of several million signals exchanged among our nerve cells. The demands of everyday life leave little time or reason to think about how we do or what we do. Yet at any given moment innumerable and unnoticeable communications are occurring within our central nervous system like when we wake in the morning and shake off the impressions of a dream; when we go out for a walk, recognize a friend, and cross the street to say hello. The works of the nervous system convey perceptions and states of mind that we can recognize and put a name to, and they make it possible for us to exchange signals, through language and in other forms, with other beings like ourselves. The brain is such an efficient “processor of information” that most of the time we do not realize the importance of its task. Usually only a disruption of the nervous system, through disease or injury or inherited pre-disposition—calls our attention to the brain's myriad functions. From a further research, Neuroscientists have well established that the brain has a highly robust and well-developed capacity to change in response to environmental demands. Thus, our brain is biologically ready to acquire language right from the very start of our lives; the process of language acquisition needs the means of experience. There is an opposite relationship between age and the effectiveness of learning many aspects of language – normally, the younger the age of exposure, the more successful the learning – and neuroscience has started to identify how the brain processes language differently among young children compared with more mature people. From this point of view, I can conclude that the brain is continually changing – developing – throughout life. This development is guided by both biological and experience. Genetic tendencies interact with experience to determine the structure and function of the brain at a given point in time. Because of this continuous interaction, each brain is unique. Though there is a wide range of individual differences in brain development, the brain has age-related characteristics that can have important consequences for learning. This integration takes form in structural modifications within the brain. Labels: psychology |
