    X-Plain Retinal Tear and Detachment Reference Summary Introduction The retina is the layer of tissue in the back of the eye that is responsible for vision. It is attached to the choroid tissue‚ which supplies the retina with blood. Retinal detachment is a disease where the retina separates from the choroid after a retinal tear develops. Retinal detachment is a serious eye condition. If it is not treated‚ it can lead to blindness. Each year‚ 30‚000 people in the United States are diagnosed

  • Retinitis Pigmentosa

    codes for proteins associated with the retina. These mutations disrupt the visual systems and often lead into blindness. The retinal cells die as a result of the mutations due to the symptoms of Retinitis Pigmentosa. Scientists are trying to bring back vision of Retinitis Pigmentosa patients though gene supplementation‚ implantation of photoreceptors‚ or implantation of electronic implants‚ to help stimulate healthy protein production in association to the retina. Vectors are commonly used to express

  • Types of cells

    ROD CELLS Rod cells‚ or rods‚ are photoreceptor cells in the retina of the eye that can function in less intense light than the other type of visual photoreceptor‚ cone cells. Rods are concentrated at the outer edges of the retina and are used in peripheral vision. On average‚ there are approximately 125 million rod cells in the human retina.[1] More sensitive than cone cells‚ rod cells are almost entirely responsible for night vision. STRUCTURE AND FUNCTION Rods are a little longer and leaner

    I. Our Senses Encode the Information Our Brains Perceive * Synesthesia- The perceptual experience of one sense that is evoked by another sense * For many years scientists dismissed synesthesia as rare curiosity or outright faking * Far more common than previously believed * Brain regions for different sensory modalities cross-activate one another * Sensation- Simple stimulation of a sense organ * Perception- The organization‚ identification‚ and interpretation of a sensation

  • Eye Floaters Research Paper

    eye. The vitreous is normally clear. It allows light to pass through to tissues at the back of the eye (retina). The retina contains the nerves needed for vision. Your vitreous can start to shrink and become stringy as you age. Then‚ strands of material may start to float around inside the eye. They come from clumps of cells‚ blood‚ or other materials. These objects cast shadows on the retina and show up as floaters. Floaters may be more obvious when you look up at the sky or at a bright‚ blank

  • Pineal Gland

    Since it is pseudoscience‚ it will not be the main focus of the study. OBJECTIVES In this study‚ the embryonic‚ morphologic‚ anatomic‚ and phylogenetic aspects of pineal gland development were reviewed. The relationship between pineal gland and retina were examined based on their morphological‚ functional and structural similarities and differences. Additionally‚ the comparative evolutionary study of the pineal gland across vertebrate classes was put with emphasis. Furthermore‚ its potential to

    of transforming the light that falls on your retinas into an actual visual image happens unconsciously and automatically. The subtle changes in pressure against your skin that allow you to feel object occur without a single thought. In order to fully understand how the perception process works‚ we’ll start by breaking down each step. The Steps in the Perceptual Process 1. The Environmental Stimulus 2. The Attended Stimulus 3. The Image on the Retina 4. Transduction 5. Neural Processing 6. Perception

  • What Process light goes through as it enters the eye travels to the brain?

    expanding and contacting based on the brightness of the light in your environment helping you see much clearer in bright and dim light. In side the pupil the light will then move through the lens which focuses the light and displays and image onto the retina‚ the light-sensitive inner lining of the back of the eyeball. The lens is what enables us to focus on images up close‚ middle range‚ and far away. Normally the lens is focused on middle range objects‚ but when you would want to see something far away
