I would explain that sensation is when you use your senses, such as sight, hearing, touch, taste, and smell. Sensation is a mental process resulting from external stimulation. Perception is awareness. You will be aware of heat or cold. I believe that sensation and perception are very alike and work closely together.

I enjoyed learned about the eye and ear. I learned how many parts there are for each and what each part does. The eye consists of the pupil, lens, retina, iris, cornea, fovea, the optic nerve, and the blind spot. The pupil is what light passes through. The lens is located behind the pupil and focuses incoming light rays into an image on the retina. The retina is the light sensitive inner surface of the eye. The iris is the ring of muscle that adjusts light intake. This is the colored portion of the eye that you see. The fovea is the central focal point in the retina. The optic nerve is the nerve that carries neural impulses from the eye to the brain. Your blind spot is the point at which the optic nerve leaves the eye creating a blind spot. I also learned that the ear consists of many parts. I enjoy learning about how things work, so it was a great opportunity for me to learn about how the eye, hear, and brain all work together.

I read the article Best Optical Illusions Online. The writer of the article claimed how they had gotten into an arguement with another person about an illusion. The illusion was a woman going around in one direction, but then unexpectly goes the other direction. The writer talked to a women who believes that she cannot trust what she is seeing if her brain is going to lie to her. She believes that the illusion actually switched directions, but it didn't. The writer tried to explain that it was just an illusion and she was thinking about it too much, but she insisted that she was right. She questioned everything. She wondered about her eyes and what her brain was doing when it tried to make sense of everything. I thought it was interesting because it was a story and personal experience which always makes reading articles or papers alot easier. This article makes me wonder if some people do have problems where there brain will "lie" to them or if people can't understand the point of illusions.
