The 5 main ideas for this chapter are: smell, taste, touch, hearing, and vision. These ideas are our 5 senses. They are developed even before we are born. The senses are crucial for our survival and continued existence. In addition, they are responsible for enhancing our quality of life. We use them every day of our life, however many do not have the luxury of using all of them. Although people are still able to live without all of the senses, but their quality of life is reduced. The most important sense of all is sight. As humans we use thrive on this sense. Unlike the other senses, sight is used almost all the time during the day. It is said that half of our cerebral cortex is dedicated to processing photons. Sight also assists with the other senses. It can help protect them by anticipating dangers to them.
1. How does our sensitivity to smell differ from person to person?

Why does tickling someone affect them so much?
Our sensory system is made to sense change, especially when is unanticipated. This is true because your movements are not as noticeable to you as when someone touches you. When these foreign movements occur, you react very fast. It is almost like you are in defensive mode. When you get tickled the nerves are acted upon is an unforeseen and irregular way. This causes an unexpected turn events causing you to burst into laughter!
4. Briefly describe the two theories of our color perception.
The Trichromatic theory suggests we can use three sensors to view light. The three wavelengths are: yellow-red, green, blue-purple. When the colors mix they form cones. These cones allow us to view light. The opponent process theory agrees with the three different wavelengths. However it suggests some colors “block” one another. In other words, some colors don’t mix, but create a new color. This is because the firing of certain colors in the thalamus prevents the firing of other colors. For example blue and yellow make
