Document Summary
Vision light energy to chemical in retina photoreceptors, chemical to. Somatosensory- mechanical activates touch/pain/pressure receptor cells which generate ap. Taste and olfaction chemical molecules via air or food fit into receptors and activate ap. Receptive field region of the visual world that stimulates a receptor cell or neuron. Optic flow streaming of visual stimuli that accompanies an observer"s forward movement through space. Synesthesia the mixing of the senses ex feeling sound. Topographic map neural spatial representation of the body or of the areas of the sensory world perceived by a sensory organ. Sensation registration of physical stimuli from the environment by the sensory organs. Light enters eye via pupil, strikes light sensitive retina, stimulates rod/cone photoreceptors transduce light to neural activity. Images from retina are upside down and backwords. Cones are most dense at fovea specialized for color sharpest area. Myopia is near sighted long eye, focuses before retina, hyperopia is far sighted. Iris allows more or less light in.
