An Exciting Ferris Wheel of Science: New Features!

BrainSCANr’s circular graph has gotten a face lift and some new features. Jess has been busy the last few weeks adding some interactive elements to the circular graph. We’ve tossed the force directed graph in favor of a more geometric hyper tree. Visitors can still move nodes around by dragging and dropping them into new positions, but we’ve also added some new interactions as well.

Filter by category
Click a category in the circular graph’s key to remove that category from the graph.

Double-click to search
Double click the label of a node to search brainSCANr for that node. Note: you have to double click the label and not the node or it won’t work (we’re working on it).

Hover for clarity
Hover your mouse over a node to see that node’s connections highlighted as well as that node’s probable association with the search term and category. You will also see that node’s corresponding bar highlighted in the new...

...Histogram of probable association!
To better visualize the relative probable association of terms to the search term we’ve added a bar chart histogram to the circular graph. Hover your mouse over a bar to see the term, and probable association, you’ll also see the that term’s node highlighted in the circular graph.

First week recap

Wow, it's only been a week, but brainSCANr has been quite successful!

We don't have a mailing list yet, so if you'd like to keep updated in the meantime, subscribe to our RSS feed or follow Brad on Twitter. You can see what people are saying about our site at the bottom of this post.

And if you haven't seen it yet, Brad's been quoted in a recent New York Times article on the human connectome.

So far we've had just shy of 10,000 pageviews from 75 countries including Kenya and Iran. The top 5 countries by pageviews are the US, UK, Canada, Germany, and Spain. I'm very pleased to see non-English speaking countries on this list.



Social media seems to have played an important part in brainSCANr's spread, with over 30 shares on Facebook, nearly 100 tweets, and 45 points on reddit.

Here's our first glance at user trends and data examination. Because of the nature of our system, we can also examine search trends. Thus far, our top five search terms have been:

• post-traumatic stress disorder
• anxiety
• amygdala
• happiness
• depression

as well as some more... interesting searches. Sex and money are popular: terms like "sex", "erection", "money", "neuroeconomics", and so on. Also "Google". Not sure what people are expecting to find, but I have promised friends to get them Google in the brain.

I'm curious as to what kind of neuroscience zeitgeist we can tap into with this platform. Mind you, the search rankings above are a bit skewed because of some direct links to searches from external sites.

For example, Vaughan Bell over at MindHacks wrote about brainSCANr, but he linked directly to the PTSD graph, so that's definitely skewing our rankings.

"Anxiety", "amygdala", "happiness", and "depression" seem to be purely organic searches on our users' part. That said, we do show "happiness" as a search example on our main page, so I'm sure that's skewing things a bit. Also, I wonder if the up-tick in "amygdala" searches aren't motivated by the recent studies about the amygdala that have been getting a lot of press.

• Bickart, et al. Amygdala volume and social network size in humans, Nature Neuroscience.
• Feinstein, et al. The human amygdala and the induction and experience of fear., Current Biology.

By the way, I love the internet. The Bickart study shows how one's amygdala and social network sizes correlate. But the comments sections in the CNN blog I linked to above are where the real magic happens. The story states:

...keep in mind that the brain is plastic, and it's possible that the amygdala does increase in size in response to social activity.

To which a commentor said:

ExCUSE me? The brain is WHAT? Maybe on the Jersey Shore it is, but where I live, the brain is organic matter.

Anyway, we hope to do some more sophisticated analyses once more time passes and we get more data. I'd love to hear some suggestions regarding what kind of analyses we could do!

User comments and suggestions

What a couple of days! Tomorrow I'll do an update on actual usage statistics, but for now I wanted to thank the community and talk a bit about our immediate plans, as well as show you all what people have been saying about brainSCANr.

First, I'm going to be a bit of a broken record for a bit here.

We don't have a mailing list yet, so if you'd like to keep updated in the meantime, subscribe to our RSS feed or follow Brad on Twitter. Because this is a community effort, we wanted to share what people are saying about our site at the bottom of this post.



Anyway, Jess and I would like to thank everyone for their great feedback, support, suggestions, etc. We've already gotten 40 comments via the site's commenting system. Your suggestions have been great!

Based on users' suggestions, we've now got a list of over 150 new terms we plan on adding to the database after the new year. Mind you, we're both doing this in our spare time, so we can't really devote as much time as we'd like to this project. Nevertheless, we're very dedicated to it.

You'll notice we've got a bit of a teaser above showing our new category for neurotransmitters/neurohormones/etc.

Ladies and gentlemen, the ever-popular: dopamine!

You can see some obvious players here including most of the basal ganglia. There are also strong ties to disease: Parkinson's disease, addiction, depression, and schizophrenia, or to reward, and also a method: PET. This is likely due to the heavy use of PET in studying dopamine binding (such as with raclopride), and other factors.

So stay tuned!

And as promised, here are some great comments from our users, Twitter, etc.

First, some of these are biased from friends of mine, but hey, we'll take the compliments we get :)

"pretty sure that @bradleyvoytek is going to be the next @HansRosling with the brain data visualization that" via @curtischambers

"This is very very cool. Well done! I am always very appreciative when visual perspectives of research are available. Plus this type of thing is fun to sift through. My only wish is that you could provide an option to hide certain categories, or items to help clean up the map a little. But man, this is really great!" via reddit
(Note: we'll be adding that feature soon!)

"This is fantastic! This technology is good for all disciplines, not just neuroscience."
http://www.reddit.com/r/cogsci/comments/eqhu8/a_new_online_tool_called_brainscanr_visually/c1a9wgw
(Note: I've also gotten a lot of these types of comments, and I'd love to expand to other fields.)

"So cool! Brain-data viz. tool for neurogeeks!" via @carlettej

"Congratulations for the work! and specially for the initiative of sharing."

"Your work is making promising connections."

"Many congratulations and thanks for providing such an invaluable source and for helping the neuroscience community to survive the information overload that threatens to engulf us all."

"I think this would be useful if it included neurohormones and names of genes. Another thing that would be really cool would be to have an interactive, manipulable brain "minimap" in the corner where regions can be selected by visually exploring the virtual brain itself, by zooming in and out, selecting particular species, etc. It would be cool to be able to toggle particular protein densities/expression zones as colored overlays."
(Note: such good ideas! We'll do what we can to make these happen!)

"Sweet!!!"

"This is great. Really good job. Only one concern, I did not find a legend indicating what the different colors refer to."
(Note: our bad! Legend coming soon...)

"Wow this is great!"

"Awesome site guys!"

"Hi Bradley, Jessica, I just came across your site via a link from a friend, just want to feedback and say I think the concept and the execution of your idea is great."

"Jessica and Brad, Congratulations. This is a really cool tool. A few quick comments of user experience - - there is no legend I could find for the meaning of colors and symbols in the map. I guess users will get it anyway, but still..... If you are really quick, type a term like 'memory' and hit search or enter, you may miss the drop down list that opens, and then you get the Sorry, "memory" was not found' message. It took me a couple of times to understand that I should wait for the list and pick a more specific term. Anyhow, the site is great and I love the clean and simple design."
(Note: we're working on speeding things up and making the searches more organic as well)

"Hi Brad... this is great!! It's a resource that soooo many brain people are looking for not only when they need quick descriptions but even to get a quick summary of prior research on some area, phenomenon or theory. Plus, it looks like you've made it easy enough to use and the design is clean and pretty. Also I love how you made all of your resources and work public. Anyway, I thought maybe you could include the Brodman areas in here - either as stand-alone entries, or maybe joined with their descriptive counterparts (i.e. Broca's = BA45 & BA46). Good look with all of this. Congratulations, it looks great (I mean it)."
(Note: Brodmann areas will be tough... but we're looking into what we can do.)


"Eeeeeeee - I love it :) I'm going to blog about it when I get my Christmas cards done!! Also, can I put in a request for some white matter tracts? I'm really happy to make a list for you or send you a link to a good atlas?? Thanks guys, and congratulations!!"
(Note: we've got the list of white matter tracts, and the next update will include them!)

"Of course I'm sure everyone has their favorite term they'd like to add, but..."
(Note: haha oh my yes...)

"Really cool concept for a tool"

"Here it is! My vote for the best brain site for 2010. Brain function, modules and connections that are all backed by Pubmed articles all at your finger tips. Click on the manuscript link and you will see a pdf of connections in the brain that if you zoom in enough (lots and lots of zooming) you will be amazed at the detail and be able to follow the various connections."

"wow. this is all types of awesome."

So thanks for the feedback everyone! Keep the suggestions (and compliments!) coming. Cheers and happy New Year.
