Peer Review
'''1. Is it obvious to you which sections of the article have been revised? Is the new content relevant to the topic?'''

It is quite obvious which sections have been revised and what new sections have been added to the article to enhance its quality. There was helpful information that was added to the introduction paragraph, ‘Tissue Distribution’, such as expanding on how galanin serves its purpose within the skin, that seemed to be relevant and necessary in regards to the topic. Also, the original article only had one subheading under ‘Clinical characteristics’, which was ‘Appetite’, that only had one sentence of information underneath it. ‘Addiction’, ‘Cognitive Performance’, ‘Depression’, ‘Pain and Neuroprotection’, and new information under ‘Appetite’ was all added to this section and clearly laid out in an easy-to-decipher format. These new subheadings have information in them that seems interesting and further explains the role of galanin within the body.

'''2. What does the article do well? Is there anything from your review that impressed you? Any particular information that you found especially informative.'''

The revised article does a great job of delving into the clinical characteristics associated with galanin. Not only this, but the author has also included the new additions they have added onto the original article into clear, formatted subsections; I feel like this makes the information easy to read and easy on the eyes. I appreciate how most of the sentences are not too long and are very quick to make their point, especially since Wikipedia wants us to make sure that we are concise and not adding a vast amount of “fluff” to our projects. The section that I really took interest in was the portion on depression; I felt like the author had a lot of good information about galanin in relation to this characteristic. I had previously known that noradrenaline and serotonin were involved in the expression of depression, but I did not know that galanin was believed to moderate these neurotransmitters.

'''3. What overall adjustments do you suggest the author apply to the article? Why would those changes be an improvement? What's the most important thing the author could do to improve the article?'''

I think that if the two subsections, ‘Addiction’ and ‘Cognitive Performance’, were expanded on further, then it would make the article even stronger. The portion on addiction seems like it would be super interesting, and though it already brings more value to the article, I think that adding on to it would be beneficial. Also, since the section on cognitive performance only has one sentence underneath it right now, I think that expanding on that subject will help the audience better understand this cognitive aspect surrounding galanin. The sentence reads: ‘Galanin participates in cognitive performance and has been shown to weaken learning and cognition’. How does it weaken learning and cognition? What kind of cognitive performances does it engage? Also, I think it would be helpful to add a picture to display, which is something I need to do for my own article. I think the most important thing that can be done to improve the article would be to add some information to the very beginning of your article about what galanin actually is. As the reader, I could learn from context clues what it seems to be and where it is located and its purpose, but I didn’t really get a clear picture of what it actually is.

'''4. Did you notice anything about the article you reviewed that could be applicable to your own article? Let them know.'''

Since I am doing an article revolving viability assays, I could probably look into assays that have incorporated galanin in various studies that have been completed. I did not notice anything that really stood out to me as an overlap between our two pieces, but I will definitely do a little research to see if galanin has been observed in any viability assay studies. However, I did really like how the subheadings were clearly defined and how the material within those headings was straightforward. I think that this kind of layout would be a good tactic for some of the information that I have within my article as well. I may try to use some of this formatting within my our separate topics that need to be divided for clarity.

5. Is all new content backed up by a reliable source of information?

After searching through the sources that were given for the information present in the article, I found that the articles used seemed to be coming from trusted journals and publishing sites. They all seemed to be scholarly articles that had focused topics based around the topic at hand. Also, the in-text references are used frequently and properly, indicating to me that the information proposed in each sentence comes from a reliable source and is marked as such. Quite a few of the articles are sourced from an online scholarly source known as ‘Springer Basel’, which seems to contain many useful scientific articles. All of the articles chosen had the word “galanin” within the title, showing me that the writer selected pieces that had strong evidence about the subject.

'''6. Are the sources fairly current (> 2015)? Check a few links. Do they work?'''

Five of the journal articles were published before 2015 but during or after the year of 2010. Two of the journal articles were from 2018 and 2019, so they are pretty current in regards to this subject. After clicking on all of the links, they all brought me to what seemed to be the correct page for the article. I did not have any difficulties tracking down the articles that were presented in the writing. The in-text citations seemed to work properly as well. Something that I was thinking about for my own article and something that may work for this one too is actually linking things to individual words within the text. This may not be necessary and may be worth more hassle than not, but it was something that I had questions about and found helpful in other articles I have read.

7. Summarize any typographical/grammatical errors that you found.

I only noticed a few, very minor grammatical errors. “In the hypothalamus, it is for example found in the ventrolateral preoptic nucleus where it has sleep-promoting function.” I would put a comma after “is” and after “example”. Also: “Currently, one of the potential mechanism for this is that galanin stimulates the hypothalamus-pituitary-adrenal axis which leads to an increase in glucocorticoid secretion.” I would make “mechanism” plural and stick a comma after “axis”; also, when you say “potential mechanism for this” I was wondering what the “for this” was referring to. Expanding on this notion might help clarity! Lastly, “Sensory neurons increasingly release galanin when they are are damaged.” The double “are are” was just a typo, I know, but I wanted to let you know. The writer has nice transitions; I would just make sure those transitions are used as often as possible to help with smoothness.

'''8. Student authors are responsible for all images on their page (even if not part of their revised subsection). Double check the original page to make sure images are acceptable and clearly described. See associated tutorial to review Wiki image requirements. Summarize your findings.'''

When I searched for the original article, I did not seem to find any images from what I could see. There did appear to have some charts with information on them, but this information seemed to be intertwined with the other information present. It seems like these may have been made by one of the original authors. I do think that it would be a good idea to have some sort of visual picture to represent the information in the article. Once an image is added and is cited by the Wikipedia standards, I think that it will help the reader better understand what galanin is and how it works.

'''9. Identify at least one additional reference that you think may contribute to the article. Explain why you think this article would benefit from the new information. Be sure to provide the reference in your write-up.'''

Ch'ng, J. L. C.; Christofides, N. D.; Anand, P.; Gibson, S. J.; Allen, Y. S.; Su, H. C.; Tatemoto, K.; Morrison, J. F. B.; Polak, J. M.; Bloom, S. R. (1985-10-01). "Distribution of galanin immunoreactivity in the central nervous system and the responses of galanin-containing neuronal pathways to injury". Neuroscience. 16 (2): 343–354. doi:10.1016/0306-4522(85)90007-7. ISSN 0306-4522.

I found this source that relates galanin to cognition and workings in the brain, but it also looks into how galanin is associated with injury. There are a lot of good subgroups that have been added to the galanin article by this author, so I wanted to be able to provide them with another one in case they wanted to expand on injury and galanin. When I read a little about this, it seemed interesting to me, just like the addiction and depression pieces that were talked about in the present article. I had mentioned that adding a little more to the cognition portion may be beneficial, so something from this article could be used for that as well.
