Tutor Marked assigment 03 - Science of the senses - Essay ExampleThe various cones be sensitive to diametric light of different wavelength. The three cone cells are usually determine as S, M and L, which denotes short, medium and long wavelengths respectively.As explained by the tricolor vision theory, the brain cannot be able to figure out the different colors, since the response given to the sensed light greatly depends upon the wavelength and the saturation level of the light. For this reason, the talent of perceiving the color requires interaction of two or more types of cone. The interaction between two different cones enables the brain to compare the intensity of the signals, and hence differentiating the colors.The opponent theory puts some more lighting to the trichromatic vision theory, by stating that the cone photoreceptors are linked to produce three colors pairs which oppose. The color pairs determine by the theory are blue/yellow, red/green, and black/white. Th e theory explains that, whenever one of the pairs is activated, no otherwise can be activated at the same time. Likewise, it explains that no two members of a given pairs are visible at the same location. This is why a person cannot see a color deal reddish green. The theory also provides an explanation for deficiencies, whereby people with dichromatic deficiency confuse colors. E.g. red and green.The ability of the body to sense a stimulus is called sensory modality. The sensory modality is based on the quint senses. For the body to sense the stimuli, the stimuli must stimulate the receptor. Once the stimuli activate the sensory schema, a perception of the stimuli is done, by dint of coding. The effectiveness of the sensory system to finger out the stimuli is greatly influenced by a number of factors, including the intensity and position of the stimuli. For better interpretation of the stimuli, several sensory are sometimes combined.Vision sensory system can be affected by the
