UCSB/KITP Emerging Techniques in Neuroscience videos

Friend of the blog Jacob Robinson (who himself is pioneering impressive new techniques with nanowires for neural recording) writes:

While we’re all distributing scientific resources, I thought I’d point out that the KITP has a wonderful program on Emerging Techniques in Neuroscience, currently underway at UCSB. They have a great lineup of speakers with some overlap with the Allen Institute program. Videos of the talks are being posted online here.

So many good videos from good neuroscientists (including Chuck Stevens, John Hopfield, Clay Reid, Jeff Magee, Guoqiang Bi, and many more)… it’s going to take me a while to get through these. Enjoy!

LabRigger: New blog for neuroscientist-engineers

Today one of our readers brought a new blog to my attention.

LabRigger is a how-to blog with a fresh look (kudos for the design and typography) that already has many interesting and relevant posts up for scientists who like to build. (You know who you are…) Furthermore, it seems especially geared toward neuroscientists and physiology folks. I’ve already added this one to my browser’s bookmarks.

Here are some of my favorites from quickly perusing the site: Printable bolt size charts, Tips on intrinsic optical imaging, Comparison of high NA, low mag objectives, and my favorite, Catalogs as textbooks. (I still remember a neuroscience faculty member here at MIT who told me that he brings science catalogs along on his vacations as “leisure reading” to stay up-to-date on new tools and to generate ideas for experiments.) In fact, I wanted to read just about every post on this blog and I think you will too! And if you’re the author of this blog, please introduce yourself in the comments, too.

Transcranial Pulsed Ultrasound Stimulates Intact Brain Circuits

Yusuf Tufail, Alexei Matyushov, Nathan Baldwin, Monica L. Tauchmann, Joseph Georges, Anna Yoshihiro, Stephen I. Helms Tillery, William J. Tyler. Transcranial Pulsed Ultrasound Stimulates Intact Brain Circuits. Neuron, Volume 66, Issue 5, 681-694, 10 June 2010.

In motor cortex, ultrasound-stimulated neuronal activity was sufficient to evoke motor behaviors. Deeper in subcortical circuits, we used targeted transcranial ultrasound to stimulate neuronal activity and synchronous oscillations in the intact hippocampus. We found that ultrasound triggers TTX-sensitive neuronal activity in the absence of a rise in brain temperature (<0.01°C). Here, we also report that transcranial pulsed ultrasound for intact brain circuit stimulation has a lateral spatial resolution of approximately 2 mm and does not require exogenous factors or surgical invasion.

ConnectomeViewer – Multi-Modal Multi-Level Network and Neuroimaging Visualization and Analysis

Two neat tools concerned with the “connectome” (i.e. the pattern of connections in the nervous system):
