Talk:2011 Group 1 Project
Post Peer Assessment Discussion
Hey guys in response to the peers i moved around my pictures, gave them text under them, and added a lot of new information and some photos to the structure section. the only issue we have left is to clean up our reference list since it mostly looks like a bunch of pubmed IDs. i guess we will ask mark what to do with this.--Michael Orenstein 21:48, 25 May 2011 (EST)
- This is the week before the mid-session break.
- In the lab this week we will have an opportunity to discuss any issues which are slowing progress on your project.
- The Thursday of the week beginning 02 May will be when all projects will be open to Peer Assessment.
- What you have on your page by Thursday of that week will be the content that others in the class will comment upon.
- I see many groups now have subsection titles for their projects.
- Here are some searches: Pubmed search all databases junction | PLoS junction | JCB junction You can now simply put your own search term into each top window.
- Now's the time to get your images, movies, media etc uploaded. Biomed central | JCB | JCB Archive | PLoS. Once uploaded you can make a gallery on either your project or discussion page using <gallery>File:name here</gallery> tags with your image files listed between the tags. When you upload project images, add this text as it appears replacing # with your own Group number to the summary information [[Category:2011Project#]].
- Shown below are the criteria that will be used to assess your final project.
Group Assessment Criteria
- The key points relating to the topic that your group was allocated are clearly described.
- The choice of content, headings and sub-headings, diagrams, tables, graphs show a good understanding of the topic area.
- Content is correctly cited and referenced.
- The wiki has an element of teaching at a peer level using the student’s own innovative diagrams, tables or figures and/or using interesting examples or explanations.
- Evidence of significant research relating to basic and applied sciences that goes beyond the formal teaching activities.
- Relates the topics and content of the Wiki entry to learning aims of cell biology.
- Clearly reflects on editing/feedback from group peers and articulates how the Wiki could be improved (or not) based on peer comments/feedback. Demonstrates an ability to review own work when criticised in an open edited wiki format. Reflects on what was learned from the process of editing a peer’s wiki.
- Evaluates own performance and that of group peers to give a rounded summary of this wiki process in terms of group effort and achievement.
- The content of the wiki should demonstrate to the reader that your group has researched adequately on this topic and covered the key areas necessary to inform your peers in their learning.
- Develops and edits the wiki entries in accordance with this sites wiki guidelines.
By Week 5
Each Group member has added to the discussion page:
- A Review Article
- A Historic Research Article
- A Current Research Article
No two students should add the same paper and there should be a link to the original article.
Hey guys .. great work .. yayy !! everything is looking much better now .. :) thank u everyone ... xoxo--Navneet Ahuja 01:43, 12 May 2011 (EST)
hey guys its looking good! try to fill up the glossary a bit more, otherwise I cant think of anything else to add besides that =D --Mark Woods 22:13, 11 May 2011 (EST)
Hey guys, its looking gud.. can anyone think of any last minute inclusions before peer review? nice work guys =)--Mark Woods 00:38, 11 May 2011 (EST)
Hey .. lol awesome mark .. !! and i have neuro anat essay due on fri and my cofa thing due tonight .. but seems like everything is coming together now !! yayy .. good work everyone .. Meedo = L-O-V-E ur hand drawn photo !! seriously its gorgeous !!! ... if u want we can even use that for the group profile page .. its very nice .. worth waiting for hehe .. as for nathan .. i think the intro you uploaded is not here ?? I remember u telling me u already posted it up .. but its not appearing ? can u reupload ?? !! GREAT work guys .. !! i love our team !!!!!!!!! xoxo --Navneet Ahuja 21:54, 10 May 2011 (EST)
fair enough nany great work, ill fix up mine with references and adding to the glossary tonite =) wat other assignment do u hav? --Mark Woods 22:27, 9 May 2011 (EST)
hey guys ... i think its time to upload the rest of the photos and the introduction ?? its due this thursday for peer assesment and right know its still incomplete..plus the glossary is still very empty .. i will try to add more words but if u guys come across some special words in your own sections please add them in .. i am just a little worried about the page since i wouldnt be able to do anything on weds night with another major assignment due .. :) .. thanks guys ..xoxo --Navneet Ahuja 17:17, 9 May 2011 (EST)
Hey guys .. i have just added the current research part with a pic .. i am not sure if its ok ? can somebody read through and let me know ?? i am a little lost lol .. thanks guys .. :) --Navneet Ahuja 21:27, 8 May 2011 (EST)
ah yea now i remember, il organise some of the stuff ive already got for future research =) --Mark Woods 23:02, 4 May 2011 (EST)
hey all, im putting my stuff up tonight but im on a mac so my pictures wont be up til i can get on a windows with paint lol. Also ive got some future research stuff so ill do that part...but wernt we all gonna add something to it?--Nathan Weller 21:42, 4 May 2011 (EST)
I went through library textbooks =) i realise these ones are a little dull, perhaps ill replace them with more colourful ones after the perr assessment.. isnt nathandoing future research? nany, how bhout doing the intro? that counts as a section lol we wanted to save it til last just to c how our page wud look. wat do u think?--Mark Woods 17:13, 4 May 2011 (EST)
Hey guys .. I was thinking that the 2 left over sections should be spliited up between me and nathan since both of u had already done 2 sections each and i dont mind doing the current research section .. !! I just hoped we divided the sections earlier - otherwise .. good work guys and yes mark i do love ur photos .. where did u manage to find these from ??!! :P --Navneet Ahuja 15:05, 4 May 2011 (EST)
I'm happy to do introduction " simple version" then we can modify it or play around from your own sections!
But I'm not sure about the Development and current research! --Maqdad Al Saif 15:01, 4 May 2011 (EST)
hey guys, ill upload pictures of my section later today. Check it out, it goes fairly in depth and I tried to keep it simple but a lot of it seems pretty technical. Let me know if it's too much for the peer level, the pictures and stuff in my section will reinforce what is written.. I can change if necessary of course. Also, who wants to do the intro? :P --Mark Woods 10:14, 4 May 2011 (EST)
Hey .. I am a little confused with that one too .. but i think what he said today was we need all the content up and if the references is giving us trouble (computer hang) then we can slowly fix it later .. as for when its due .. (in the announcement it says next week but is it only for groups that is finding difficulties in ref ?? i am not entirely sure .. I like what meedo said of having a photo in each section and i have just added mine .. well i edited the photo (since the lisence allow me to) and labelled the key structures .. anyways I also added one funky image in the gallery its called "stained neurons" !! :)
meedo i was reading through ur section and loved it .. but i thought
"the nerve impulses are conveyed through the action of what is called neurotransmitters including " is it better to say conveyed "through chemicals or Chemical actions " since neurotransmitters are simply chemicals molecule but if you like it the way it is then its fine with me too :P --Navneet Ahuja 22:22, 3 May 2011 (EST)
do we need references completed for the peer assessment?
Hey guys .. AWESOME WORK !!! lol .. really loved the history section .. may be a "history timeline" but .. i read through all of them and like what meedo said .. its easy to understand .. !! and of course we could have both the gallery and pictures through out the page .. i just thought its going to be just in the gallery .. sorry for the confusion .. and history must have involved huge amount of research ??!! great work mark !! .. Ohh and as for the your part .. i liked it and i think it is related to synapse like what you said .. you need to explain about action potential before you can start talking about the release of neurotransmitters !! Ohh and nathan .. - i know i told you its due next week but as the announcement says .. i think we should try and finish everything as soon as possible ?? everyone think so ?
As for meedo .. dont worry about it .. ur section looks awesome .. love the background research !! --Navneet Ahuja 21:12, 3 May 2011 (EST)
no worries meedo! ur sections are looking gud, the writing style is very effective if this page were an educational tool =)
Ok guys, I want u to check out the first half of my section. A lot of this is outlining in a basic way how the nervous system works and y. Let me know what you guys think bout it, it felt weird writing stuff not directly linked to the synapse lol but i felt it is still important in understanding their function.--Mark Woods 20:27, 3 May 2011 (EST)
Hey Guys, sorry for being out of touch! Since i got problems uploading my things mainly due to my internet connection and my references... Mark, I like the simplicity of the history--> easy to read and straight to the point! after we add up all things together we can have a look at the overall process and whether additional historical information will be useful or not :)
and for the images, I agree with the idea of leaving an illustrative picture beside the text of the disease! " that way we can picture it in our heads" but I reckon having at least one image for each section will look better and less boring. what do you guys think?
As for me, I will upload some EMs and my sections will be filled! and my own drawings... If there's any comment or a need for adjustments, please feel free to do so and make a note that it has been changed.
Hope to see some awesome Synaptic junction page :D --Maqdad Al Saif 18:34, 3 May 2011 (EST)
hey guys what do u think of the history? i kept is breif and stuck to the main events, I don't think this section should take up too much space on the page, but there's still other events that did take place which I could include. --Mark Woods 18:03, 3 May 2011 (EST)
Good point Nany. And ur rite, images should be throughout the page as per usual, so don't let the gallery throw you off! I was hoping the gallery would be a place for addional images and such. Also, I don't see a problem with using an image in a section and having it also available in the gallery, what do u guys think? --Mark Woods 11:27, 3 May 2011 (EST)
I loved the images mark !! .. and I am going through the images too .. as for nathan .. my "abnormalities" section already mentioned all the diseases so you can just find a couple of article with images to go with some of the diseases listed .. hope that makes it easier .. and guys i was thinking should all the images be in the gallery ?? I think esp for the disease section it should be right next to the diseases .. like .. text on the right hand side and images on the left ?? what do you guys recon ??!! but good start mark .. :) xoxo --Navneet Ahuja 08:32, 3 May 2011 (EST)
hey guya, worked out the gallery lol. sso when u add an image, type Image:file name|what name you want to appear --Mark Woods 02:08, 3 May 2011 (EST)
Hey Nany, hav u come across any images for the gallery? we're thinking EMs, diagrams, just a bunch of helpful pics n vids. I don't think we've set up the gallery yet, but when we do we can add to it before and after peer assessment, so keep that in mind =) --Mark Woods 15:03, 2 May 2011 (EST)
Hey mark .. i totally agree with the position of the title .. i think synaptic integration comes before neurotransmitter and very happy for u to change .. !! as for nathan - i am glad its almost done .. cant wait to see it .. and i agree with nathan that we all should start putting up resources for the current studies as well as photos .. i tried finding images but seemed like i have to look through them again during this weekend.. !! anyways .. as for the meeting .. did i miss out on anything ??!! and if u guys need any particular help on any sections .. please do not hesitate to let me know .. xoxo--Navneet Ahuja 19:45, 30 April 2011 (EST)
nice nathan. hey meedo, how in depth are you going to go into the function of the types? If not a lot, I can use my section to go into a fair bit of depth. What do you think? --Mark Woods 10:03, 30 April 2011 (EST)
hey just wanted to say good work yesterday, everythings starting to come together now. My diseases part is almost done and should have it up by the end of the weekend. everyone by due date try and add some things to the new research part if you can. --Nathan Weller 12:47, 29 April 2011 (EST)
nice work nany =) i switched around our sections, so synaptic integration comes before neurotransmitters, is that okay? I figure it makes more sense since I'm going to be talking about the presynaptic action potential, before neurotransmitter release.
--Mark Woods 11:42, 29 April 2011 (EST)
Hey there .. i just wanted to tell you guys i added a little tiny bit of glossary just to get it started .. !! lol I think its relevant to my section and will keep adding it once i find more info .. !! And thank u mark for letting me know the due date .. I thought it was on the 1st of May !! anyways .. hope u see u guys real soon .. xoxo--Navneet Ahuja 21:36, 26 April 2011 (EST)
hey nany, hope ur break is going well :) great work with the neurotransmitters section.the rest of us are planning to meet up on thursday to do some project work. the peer review is due the thursday of the week back, so we need the bulk up by then!
--Mark Woods 19:03, 26 April 2011 (EST)
Hey again guys .. I already did my part which is the neurotransmitters (although some of the references are missing .. i will slowly add them up !! Lol ..) please feel free to add or delete anything up there..!! I just realized i will be missing the group meeting .. please update me here of whats going on .. sorry again guys for not being able to attend the meeting .. and if you need my help for anything just post them here .. i promise to check it regularly lol!!! xoxo --Navneet Ahuja 03:49, 26 April 2011 (EST)
hey guys .. i saw that my section is neurotransmitters .. am more than happy to do it !!! I will totally keep in touch and start adding on my parts little by little .. sorry for not being there at todays lab though !! (hope i didnt miss out on alot??) anyways .. just letting you guys know great work with the subheading !!! Laslt, does anyone know if when this is due ? is it still on the 1st of May ? cya soon guys ... !!! xoxo --Navneet Ahuja 12:31, 21 April 2011 (EST)
Ok so those subheadings work;
2) History? --> although I'm not sure if that's easy to find! however if it's important to be included, why not?
3) what is synaptic Junction? a different pictures
4) types of synaptic junctions! Table is essential + images to demonstrate the difference between types!
6) Synaptic integration
7) Diseases associated with synaptic junctions dysfunctions--> pictures needed!
8) Current and future research and developments ( where it's aimed, potential medical applicaitons)
9) Gallery (pretty much just thumbnails showing a whole lot of images we've come across. Will help ppl with visualizing)
--Mark Woods 10:43, 21 April 2011 (EST)
Let me start by Saying that a Proper meeting would be great to See what parts we are going to write about. Since I find it a little difficult to see comments about neurotransmitters or types of synaptic junctions. I reckon it would be wonderful if we meet up and write the outline of the project for a start. After all, we can get starting with an actual progress! I know all of us want to get a good grade for this subject and get the most out of it! Note: it's essential for the meeting to be prior the holiday :)
What do you guys all think? Sorry for all that, it's my first time doing online project and stuff, so my way is by actual meetings
Oh, and I like the idea of neurotransmitters + synaptic junctions types!
A simple Outline I see commonly is;
3) what is synaptic Junction? a different pictures
6) Synaptic integration
7) Diseases associated with synaptic junctions dysfunctions--> pictures needed!
8) Future research or developments!
Hope that wasn't much for a start!
--z3284061 22:53, 20 April 2011 (EST)
a section on neurotransimmtters is a gud idea, theres plenty in this textbook i got which we can use as a starting point. Also, the book (Principles of Neuroscience 4th edition- Kandel) splits up synaptic junctions as either chemical or electrical. Here is a little from it's intro pages:
Two types of synapse, electricaland chemical. Chemical synaptic junctions have synaptic clefts , electrical synaptic junctions have gap junctions 176.
Electrical distance between pre and post synaptic cell membrances: Electrical is 3.5nm and chemical is 30-40nm.
Electrical transmission is graded and occurs even when the currents in the presynaptic cell are below threshold for an action potential. 178
I think it would be helpful in terms of a starting point to look for additional references, as well as a good reference itself. ALso, we should cover synaptic intergration and modulation by second second messengers. What do you guys think?
I'm also happy with being allocated any subheadings =)
--Mark Woods 20:11, 20 April 2011 (EST)
hey guys --i totally agree with mark that we gotta start splitting up and i think the types of neurotransmitters should also be included somewhere in the page and i am more than happy to do anything u guys assign to me but in particular - i dont mind doing this table thing !! I will be missing thursday lab but of course i will be in touch and like what i said .. i am happy to do anything and i guess we should really get started since the deadline is not very far away .. ?? do u guys think we should do the timeline too ??!! --Navneet Ahuja 00:06, 20 April 2011 (EST)
Okay guys lets start getting some stuff up. So should we divide up the subheadings and each work on one? Some of the sections seem bigger than the others, maybe the Role shud be included in the intro?
--z3254753 21:08, 19 April 2011 (EST)
Hey guys, realised my historic article probably isn't old enough. Here's another one from a fair while back
Pharmacology and Nerve-endings (Walter Ernest Dixon Memorial Lecture): (Section of Therapeutics and Pharmacology)
--Mark Hill 17:02, 30 March 2011 (EST) OK Group 1, No content has been added to either your discussion or project page. You were meant to have already begun looking into both the topic and references, pasting links on your discussion page. I will see you in the lab tomorrow to discuss whether you are having problems or are simply not doing the work. This search should get you started. Search Pubmed: Synaptic Junction
Hey everyone. I was doing some research on our topic but it will be so similar to one of the other pages being done. Have a look yourself before tomorrow and we should make a final decision in the lab if this is what we should do.--Nathan Weller 23:37, 30 March 2011 (EST)
Good Idea, we should make a final decision before we can start posting references. See you guys tomo --z3254753 00:14, 31 March 2011 (EST)
hey guys ... sounds good .. and nathan i think u put the content in the wrong page.. (its in group 2's page) lol .. :) --Navneet Ahuja 09:11, 31 March 2011 (EST)
I think Nathan has done a remarkable Job for a start :)... Well, we can re-adjust it and have a look at the previous projects for more enlightments.. Maqdad Alsaif
Hey guys i did research some articles and here are some of it --Navneet Ahuja 16:12, 2 April 2011 (EST)
1)Synapse Formation in Developing Neural Circuits - general discription on how synapse work !!
The nervous system consists of hundreds of billions of neurons interconnected into the functional neural networks that underlie behaviors. The capacity of a neuron to innervate and function within a network is mediated via specialized cell junctions known as synapses. Synapses are macromolecular structures that regulate intercellular communication in the nervous system, and are the main gatekeepers of information flow within neural networks. Where and when synapses form determines the connectivity and functionality of neural networks. Therefore, our knowledge of how synapse formation is regulated is critical to our understanding of the nervous system and how it goes awry in neurological disorders.
Synapse formation involves pairing of the pre- and postsynaptic partners at a specific neurospatial coordinate. The specificity of synapse formation requires the precise execution of multiple developmental events, including cell fate specification, cell migration, axon guidance, dendritic growth, synaptic target selection, and synaptogenesis (Juttner and Rathjen in Cell. Mol. Life Sci. 62:2811, 2005; Salie et al., in Neuron 45:189, 2005; Waites et al., in Annu. Rev. Neurosci. 28:251, 2005). Remarkably, during the development of the vertebrate nervous system, these developmental processes occur almost simultaneously in billions of neurons, resulting in the formation of trillions of synapses. How this remarkable specificity is orchestrated during development is one of the outstanding questions in the field of neurobiology, and the focus of discussion of this chapter.
2) Review: disruption of the postsynaptic density in Alzheimer's disease and other neurodegenerative dementias.
The most common causes of neurodegenerative dementia include Alzheimer's disease (AD), dementia with Lewy bodies (DLB), and frontotemporal dementia (FTD). We believe that, in all 3, aggregates of pathogenic proteins are pathological substrates which are associated with a loss of synaptic function/plasticity. The synaptic plasticity relies on the normal integration of glutamate receptors at the postsynaptic density (PSD). The PSD organizes synaptic proteins to mediate the functional and structural plasticity of the excitatory synapse and to maintain synaptic homeostasis. Here, we will discuss the relevant disruption of the protein network at the PSD in these dementias and the accumulation of the pathological changes at the PSD years before clinical symptoms. We suggest that the functional and structural plasticity changes of the PSD may contribute to the loss of molecular homeostasis within the synapse (and contribute to early symptoms) in these dementias.
3)Recent research Early Events of HIV-1 Infection: Can Signaling be the Next Therapeutic Target?
Intracellular signaling events are signposts of biological processes, which govern the direction and action of biological activities. Through millions of years of evolution, pathogens, such as viruses, have evolved to hijack host cell machinery to infect their targets and are therefore dependent on host cell signaling for replication. This review will detail our current understanding of the signaling events that are important for the early steps of HIV-1 replication. More specifically, the therapeutic potential of signaling events associated with chemokine coreceptors, virus entry, viral synapses, and post-entry processes will be discussed. We argue that these pathways may represent novel targets for antiviral therapy.
4. Historical research ACTION OF ADRENALINE ON SYNAPTIC TRANSMISSION AND ON ADRENAL MEDULLARY SECRETION 
and lastly this article might be helpful to us old neurons
I found I've covered a fair bit of relevant stuff in my lecture notes for another course lol. Maybe they could help us direct our research a bit. Speak more about it in person in the lab :)
here are my research articles;
Gray Matter NG2 Cells Display Multiple Ca-Signaling Pathways and Highly Motile Processes. - current research
The importance of sensory nerve endings as sites of drug action. - review article
