November 2nd 

In the last journal, I re-iterated my need-to-know: What issues in the brain lead to vision loss/blurry sight? I also refined my sub-questions to guide my research:

1) How are light signals turned into electric signals for the brain?

2) How does the brain work to help you see?

3) What causes issues in the brain?

I also stated what categories these questions fall into on the HOTQ's spectrum. This post will focus on their relevance according to the SPECS guidelines instead.  

Significance - These essential questions are crucial to my research on the impact of brain-related injuries/diseases on vision because they follow a logical process for me to process information one tiny topic at a time. Also, each question relates to my need-to-know and helps expand on different areas of the topic, making them vital to my study. My first question helps me understand what I stated in my first SDA about brain signals, while the second question pushes me to dive deeper into the function of the brain, and the final question is where I get to figure out what could go wrong in this process. 

Perspective - These issues affect everyone. There are numerous amount of brain injuries that can develop, whether it be from birth, hitting your head, or anything that starts later on. The brain is vital to all people and is something we all share in common. Many parts of the brain play roles in vision, so it is a widespread area that can mess up people's eyesight.

Evidence - When starting my initial research, I found that "40-50 percent of the brain is involved in vision". The correlation between neurology and eyes is significant, as they are more connected than I thought. Also, "20-40 percent of people with brain injury experience related vision disorders", which shows the number of people and eyes the brain impacts (Brainline). 

Connections - Eyes, especially with the statistics given, are connected to the brain, meaning vision and neurology have crossovers. While studying one, you inevitably run into the other. Even further, these subjects could join with chemistry, as molecules matter in everything, especially the human body.

Supposition - How might it be different if issues were caused by the brain rather than the eyes themselves? That question is the new approach I am trying, stemming from my last SDA that had focused on eye-internal issues. In the October SDA, I had mentioned the brain and its role in vision in passing, but looking back and reflecting/supposing from my previous work is what got me thinking about this month's focus: the neurology behind eyesight.
