04 Jan Chapter 3 Discussion Forum

1- The science of seeing is truly magnificent. It’s interesting to think about how some people need to wear glasses while others don’t. One of the photos in chapter 3 says that “an individual who experiences low vision would not be able to have their vision corrected with normal glasses.” My question to you is do you wear glasses or know someone close to you that does? What are your personal benefits and what are the cons of wearing glasses in your opinion?

2- Chapter 3 talks about habituation and sensory adaptation. When I spend the night in a different place than usual (a hotel room, for example), I have a hard time falling asleep if there are repetitive/constant noises in the room. Eventually, I am able to tune them out and go to sleep. Would this be considered habituation or sensory adaptation? Why? Do you experience habituation or sensory adaptation in your life?

1- Chapter two- There was so much informal in chapter 2 but I wanted to focus on the nervous system and what role it plays in our lives. The book states that “damage to the central nervous system was once thought to be permanent. Neurons in the brain and spinal cord were not seen as capable of repairing themselves.” What type of research went into finding out that damage to the central nervous system can be repaired and how long did it take to find out?

2- Chapter 2 gives us the opportunity to look inside the living brain and teaches us the various structures and how they are responsible for different functions. Consider Phineas Gage, the brain trauma he experienced, and how that trauma affected him. What brain structure or structures do you think are most cruical to everyday functioning?
