The Brain And Optical Illusions Essay, Research Paper My project question is, How fast does the brain read geometric shapes compared to optical illusions? I will try to find this out by experimenting, reading, and researching the resources that I have acquired. I have planned my experiments using two simple procedures. In the first, I will draw a puzzle of different color shapes. I will give the test subject a piece of paper with a shape from the puzzle on it. I will have them study the paper. Then I will reveal the puzzle to them and ask them to find the shape as fast as they can. Each subject will be timed in order to determine how long it takes the individual to find the shapes. As for the second procedure, I will show them an optical illusion called The Hidden Word and

ask the test subject to tell me what the word is. Again, the subject will be timed in order to see how long it takes for him or her to find the hidden word. I hope to discover which figure the brain can read faster. To complete this project, research must be done on the brain. The brain is the most important organ in the body. It makes everything in your body function. Your brain tells you when you are hurt or sick and does many other important things for you. Think about it; it runs everything in your body without you needing to think about it, perfectly! The brain has seven main parts. They are: the thalamus, the hypothalamus, the cerebellum, the brain stem, the corpus callosum, the two hemispheres, and, the largest part of our brain, the cerebrum. The thalamus is located just

above the the brain stem. It acts like a switchboard, deciding what to do with the messages that come to the brain. If you were doing something, like reading, and someone called you, your thalamus would ignore that someone was calling you. The hypothalamus controls our emotions such as: happiness, sadness, and hunger. It also controls our sense of temperature. It is located right in front of thalamus.It is also one of the organs that is fully developed when you are born. The cerebellum is the part of the brain that controls our muscles. When we were born, our cerebellum wasn t fully developed. That s why we didn t do things in a coordinated manner with our bodies. We moved shakily with our bodies because messages from another part of our brain called the cerebrum weren t

organized by the cerebellum. The brain stem is located at the back of the brain, right below the thalamus. It has the responsibility of taking care of the jobs we don t think about such as: breathing, blinking, and making our heart beat. The cerebrum is the largest part of our brain. It takes care of our motor skills such as speaking, walking, and writing. These skills are operated in the outside layer of the brain, called the cortex. It is the last part of the brain to develop and is unique only in humans. The cerebrum is divided into two halves, or hemispheres. Our major learning senses are located within the two hemispheres. The corpus callosum is the connector for the two hemispheres of the brain. The corpus callosum sends messages between the hemispheres. Your corpus

callosum is able to send twenty messages per second to each special nerve cell called neurons . The brain receives messages through these neurons. Scientists believe that for every ten billion cells in the body, one billion of them are neurons. Our brain and eye work best when dealing with the contrasts of colors or shapes. This is one factor for our three dimensional sight. If a red tennis ball came to rest on a white fence it would show up immediately. Perhaps if a white tennis ball came to rest on that same white fence it wouldn t show up as easily as the red tennis ball. This corresponds with the first part of my project; finding different shapes on different backgrounds. Another factor in our three-dimensional sight is a group of fibers called optic nerve fibers. They attach
