What Is Macular Edema? Macular edema is swelling or thickening of the eye's macula, the part of your eye responsible for detailed, central vision. The macula is a very small area at the center of the retinaâa thin layer of light-sensitive tissue that lines the back of the eye.
What is perception? The process by which individuals select, organize, and interpret the input from their senses (vision, hearing, touch, smell, and taste) to give meaning and order to their environment. Through perception, people try to make sense of their environment and the objects.
Categorical perception is opposed to continuous perception, the perception of different sensory phenomena as being located on a smooth continuum. How the neural systems in the brain engages in this many-to-one mapping is a major issue in cognitive neuroscience.
