Recreating the Brain :: Biology Essays Research Papers

2001: Recreating the Brain Perhaps one of the most interesting and least understood aspects of neurobiology is human consciousness. For many, this "experience of self" (an aspect of consciousness which will be used interchangeably with consciousness in this particular paper) defines what it means to be human. Personality and emotion, and their connection to the experience of self, can yield insight into creating artificial intelligence that can mimic conscious human brain function. By discussing the implications of consciousness in computers with artificial intelligence, the significance of the experience of self within humans becomes clearer. The challenge of understanding personality may be more easily surmounted by studying the significance of personality in relation to something else, in this case alcoholism. Alcoholism is a disease that affects millions of people and is influenced by both environmental and genetic factors (1). Low self esteem and abusive relationships can lead to alcoholism in individuals who do not show a genetic tendency towards the disease. However, it is not necessarily the alcoholic's fault, or his/her family's fault, that the individual displays alcoholism. No one is destined to become an alcoholic, but it is true that a tendency towards alcoholism can be inherited. Alcoholism is twice as likely to appear in homozygous twins than in heterozygous twins (1). Children born to alcoholic parents, but brought up by non alcoholic adoptive parents, are three times more likely to develop alcoholism than the natural children of the adoptive parents (1). However, many children of alcoholic parents never have to battle alcoholism themselves (1). Therefore, it should be viewed as a disease that individuals can be predisposed towards, much like diabetes or hypertension (1). Personality traits also seem to have a role in inheriting a tendency towards alcoholism (2). Some researchers believe that, using personality traits, they can predict with 80% accuracy which individuals have the capacity to develop alcoholism (2). This implies that individuals who manifest these personality traits are most likely genetically predisposed to develop alcoholism at some point in their life. So individuals are genetically predisposed toward personality traits as well. This interplay between genetics and personality traits brings up an important point, the exact definition of the word "personality". Careful inspection of the common use of the word "personality" illustrates that it holds different meanings at different times. When an individual refers to someone else's personality, they refer to that person's tendency to behave in a certain way.
