Synesthesia and the Nature of Perception Essay example -- Biology Essa

Synesthesia and the Nature of PerceptionAlthough scientists do not fully understand the workings of the whiz and perception, the basic invention seems fairly simple on an intuitive take aim. The brain interprets iodin frozen of stimuli in a specific way. Certain people with synesthesia, however, can gene lay out a single stimulus in different ways. Are they by nature predisposed to hear red? Do these people have tautologic neural connections allowing them to taste green? Some scientists claim that all human race begin their lives as synaesthetes until they learn to differentiate their senses. It brings into question the nature of perception, and how the brain perceives reality.Synaesthetes experience cross-modal associations involuntarily, so that the feeling of one sense stimulates the sensations of some other (1). Five features for clinical synesthesia exist (1) People with the rargon chink of synesthesia experience it passively, but it requires a certain stimulus to en hance a response. The individual projects the sensations into his peri-personal space. The sensations do not change over time, and are generic, unelabo sayd sensory perceptions. In addition, the experiences are very memorable one subject said that he was merely a passive perceiver as the reminiscence unfolded itself (1). Experiments with a single synesthetic subject project perfect consistency for colour descriptions of words, compared to a 17% consistency rate of a program line subject with similar intelligence and memory levels (3). non only did the subject seem genuine, based on her high level of consistency, but she gave far more detailed and vivid descriptions of the associated colours than the control subject. In a larger group of nine subjects, the consistency rate fo... ...until the brain learns to separate sensations. The source of the connections, the limbic brain, still serves as an emotional guide to the rational objective world, giving reality different billet for each individual.
