Document Summary

Neural representation is compared with previously stored info in the brain matching process results in recognition and interpretation of stimuli perception: specific parts of the brain are specialized for different sensory functions. How much difference must there be in 2 tones before we can tell that they are not identical. The sensory systems: vision, stimulus for vision electromagnetic energy/light waves measures in nanometres, electromagnetic spectrum includes: gamma rays, x-rays, ultra violet, visible spectrum, Infrared, tv/radio waves: visible spectrum is sensitive to only 700-400nm (red-blue/violet) They"re about 500x more sensitive to light in comparison to cones, but they do not give rise to colour sensations. The periphery of the retina contains mainly rods: cones: photoreceptor cells that are colour receptors and function best in bright illumination. Fovea: a small section of the retina that only contains cones. Cones decrease in concentration as one moves away from the centre of the retina.
