Friday Paper List – April 26th

Before I start the list, there looks to be an interesting back and forth over some results in the most recent issue of Science.

  • Comment on “In Monkeys Making Value-Based Decisions, LIP Neurons Encode Cue Salience and Not Action Value” William T. Newsome, Paul W. Glimcher, Jacqueline Gottlieb, Daeyeol Lee, Michael L. Platt ; Science 2013 (link)


  • Response to Comment on “In Monkeys Making Value-Based Decisions, LIP Neurons Encode Cue Salience and Not Action Value” Marvin L. Leathers, Carl R. Olson ; Science 2013 (link)

You can find the original paper here. I need to read it and then read these comments. In my opinion there is nothing more fun than a good back-and-forth among well respected scientists!

It’s fun to watch them battle…

Alright on to this weeks list!

1) Optogenetic approaches for functional mouse brain mapping Diana H. Lim, Jeffrey LeDue, Majid H. Mohajerani, Matthieu P. Vanni and Timothy H. Murphy ; Frontiers in Neuroscience 2013 (link)

I am a big fan of the work from Dr. Murphy’s lab. I especially enjoy the amazing things he has done with Voltage Sensitive Dye (VSD) imaging, ChR2, and a bilateral imaging preparation.

You can see spontaneous activity in a control (left) and acallosal (right) mouse brain using VSD imaging of both hemispheres below.

Also if you are ever decide to learn VSD or intrinsic signal imaging I highly recommend this paper:

  • Simple and cost-effective hardware and software for functional brain mapping using intrinsic optical signal imaging Harrison TC, Sigler A, and Murphy TH ; J Neuroscience Methods 2009 (link)

2) Segregation of cortical head direction cell assemblies on alternating theta cycles Mark P Brandon, Andrew R Bogaard, Nathan W Schultheiss & Michael E Hasselmo ; Nature Neuroscience 2013 (link)

This looks very interesting! For those who study the hippocampus, it might be worthwhile to read this paper in tandem with another paper (shown below) from the same group published in 2011. That’s what I’m planning on doing 🙂

  • Reduction of Theta Rhythm Dissociates Grid Cell Spatial Periodicity from Directional Tuning Mark P. Brandon, Andrew R. Bogaard, Christopher P. Libby, Michael A. Connerney, Kishan Gupta, Michael E. Hasselmo ; Science 2011 (link)

3) Neurotransmitter Switching in the Adult Brain Regulates Behavior Davide Dulcis, Pouya Jamshidi, Stefan Leutgeb, Nicholas C. Spitzer ; Science 2013 (link)

Commentary on the above paper:

7) The neuron-specific chromatin regulatory subunit BAF53b is necessary for synaptic plasticity and memory Annie Vogel-Ciernia, Dina P Matheos, Ruth M Barrett, Enikö A Kramár, Soraya Azzawi, Yuncai Chen, Christophe N Magnan, Michael Zeller, Angelina Sylvain, Jakob Haettig, Yousheng Jia, Anthony Tran, Richard Dang, Rebecca J Post, Meredith Chabrier, Alex H Babayan, Jiang I Wu, Gerald R Crabtree, Pierre Baldi, Tallie Z Baram, Gary Lynch & Marcelo A Wood ; Nature Neuroscience 2013 (link)

8) Random convergence of olfactory inputs in the Drosophila mushroom body Sophie J. C. Caron, Vanessa Ruta, L. F. Abbott & Richard Axel ; Nature 2013 (link)

9) A Motion Direction Preference Map in Monkey V4 Peichao Li, Shude Zhu, Ming Chen, Chao Han, Haoran Xu, Jiaming Hu, Yang Fang, and Haidong D. Lu ; Neuron 2013 (link)

There is a lot I could say about this paper, but let me just say a few:

It is no coincidence that some of my favorite optical imaging papers are from the lab of Dr. Anna Roe. It is also no coincidence that they often involve the work of Dr. Haidong Lu, Dr. Gang Chen, and Dr. Hisashi Tonegawa. I have a great deal of respect for all four of these scientists. The last three were all postdocs in Anna Roe’s lab at Vanderbilt University. Haidong Lu now has his own lab at the Institute of Neuroscience in Shanghai, China.

This recent paper from Dr. Lu’s lab, in my humble opinion, reflects that he continues to produce some of the best intrinsic signal optical imaging around.

The quality of these images reminds me of two earlier papers from the Roe Lab, involving the same talented people. The 2010 paper, with a very similar title to the one published this week, contains what might be one of my all time favorite figures 🙂

What is not to love about this paper. If you haven’t seen this classic video showing the use of ultrasonic bat transducers for hearing rats laugh when they are tickled, then you are in for a treat!


Friday Paper List – April 19th

I might have mentioned I am always reading up on how there are serious problems with the current state of scientific publishing. I found this blog post: Scientific publishing as it was meant to be, which is about a new type of submission for the journal Cortex, really really interesting! I definitely think it is worth a read.

Also I just read this article over at the New York Times website about an interesting development in economics research. I can’t help but wonder what we would find if we re-examined all of the data from pivotal neuroscience publications.

Random links aside, plenty of exciting new papers this week and I’m kind of in a rush to make the post so I’ll just get right to the list of papers. Enjoy!

34) The First Level of Super Mario Bros. is Easy with Lexicographic Orderings and Time Travel . . . after that it gets a little tricky. Tom Murphy VII ; (link)

This is not published in a peer-reviewed journal, but I thought it was really awesome. You can of course watch a video here, if you don’t want to read the paper. But the paper is really entertaining and has my favorite lines out of all the papers I read this week:

“8 bits is really small. You can see them all right here: 00001111.”

CLARITY finally published!

If you were at SFN last year, you might have managed to catch a glimpse of this poster buried inside a large crowd of neuroscientists. I didn’t even attempt to see the poster up close; instead I gathered what I could from those who escaped to the fringe of the mob after seeing the poster and video demonstration playing on an ipad. Those who I spoke to where wide-eyed and giddy. They told me tales of a magical method that could turn brains invisible..

Of course making tissue transparent for subsequent optical investigation is nothing new, but then that wasn’t the whole story! Supposedly with this magical technique you could subsequently perform whole brain immuno-staining.. and not just that.. you could do it multiple times!!

Ok, so on the surface this sounds pretty cool… but then you see the videos like the one from Nature’s video channel here and you start to realize this is pretty amazing…

…then you read more about the method itself (from a commentary here and the actual publication here) and you start to really comprehend how useful this technique could be for understanding projections in the whole brain…

…and then you read that this can be applied to not just a mouse brain, but ANY brain… so you can do this to a brain from a rat, zebrafish, non-human primate … really any model organisms being used for neuroscience research! Of course you can forget using a model system and just use actual human tissue…the paper even shows an interesting finding using some human cortex from an autistic patient that had been stored in formalin for over 6 years!! …

… and then finally it makes sense why most of the neuroanatomists at SFN where walking away from the CLARITY poster looking like this…

I should add, this exciting new technique was developed in the lab of Karl Deisseroth, who you might recognize as one of the developers of optogenetics. I think it’s safe to say that he is feeling pretty good right about now.

Dr. Deisseroth this morning when the CLARITY paper was officially published.

I’ll end this overload of animated GIFs with a link to just one of several articles that are popping up all over the internet. This one had a link to a video of Dr. Deisseroth himself describing the process in an interview. You can check that out here as well.


Friday Paper List – posted Sunday April 7th

As expected on Tuesday this last week President Obama made an official statement about the BAM initiative which has now been changed to BRAIN. What followed was an explosion in media coverage, blog posts, NPR interviews, and Tweets on the subject. Here are just a few.

Here is a link for a general overview of what’s going on from the NIH website.

This page on the website seems to have links to all the different announcements.

There is a blurb here from the Nature News Blog.

I really like this blog post from Gary Marcus for the New Yorker.

Here is a blog post from someone who thinks the BRAIN initiative is a bad idea and “a missed opportunity”.

Here is a nice short blog post that gives some possible perspective on the amount of funding.

The post above lead me to this nice post from a Wired interview with Bill Newsome.

Two friends shared with me some links for NPR interviews on the subject: here and here. Thanks Michele and Omar!

And finally you couldn’t top off the media coverage any better than with the head of the NIH, Francis Collins, appearing on the Colbert Report! You can see Stephen Colbert give his thoughts on the BRAIN project and how it isn’t right to have the first letter of an acronym stand for the acronym here. And then for then check out the interview here.

In other news, research at the University of California Santa Cruz on finding out if other animals have the rhythmic ability to follow a beat like humans, has led to what might be the best video of the year.

Check out the video here. I promise you won’t be disappointed. Go straight to about 0:24 seconds in for the best part!
