Friday Papers Post: January 18th (posted on Saturday the 19th..sorry)

Busier than I expected this weekend so the post is a little late!

So I guess three weeks in and I already missed my friday deadline… posting at 1am on saturday.. so close..

Anyway enjoy the papers.

1. A polymer-based neural microimplant for optogenetic applications: design and first in vivo study Birthe Rubehn, Steffen B. E. Wolff, Philip Tovote, Andreas Lu ̈thi and Thomas Stieglitz ; Lab on a Chip 2013 (link)

I am a sucker for all toys and this one promises to let you do it all. It slices, it dices, it shines light, it delivers drugs, it records neurons, and keeps vegetables fresh for months!

2. Spectral analysis of whisking output via optogenetic modulation of vibrissa cortex in rat R. Pashaie and R. Falk ; Biomedical Optics Express 2013 (link)

Barrel Cortex and Optogenetics – that’s all it takes for me. But seriously this looks interesting.

3. Mice Create What–Where–When Hippocampus-Dependent Memories of Unique Experiences Laetitia Fellini and Fabio Morellini ; Journal of Neuroscience 2013 (link)

4. Distinct Pathways for Rule-Based Retrieval and Spatial Mapping of Memory Representations in Hippocampal Neurons Rapeechai Navawongse and Howard Eichenbaum ; Journal of Neuroscience 2013 (link)

5. An optimized fluorescent probe for visualizing glutamate neurotransmission Jonathan S Marvin, Bart G Borghuis, Lin Tian, Joseph Cichon, Mark T Harnett, Jasper Akerboom, Andrew Gordus, Sabine L Renninger, Tsai-Wen Chen, Cornelia I Bargmann, Michael B Orger, Eric R Schreiter, Jonathan B Demb, Wen-Biao Gan, S Andrew Hires & Loren L Looger ; Nature Methods 2013 (link)

It’s kind of exciting to imagine a future where we can image everything. Some kind of ideal setup where you are doing high speed imaging capturing the membrane potentials of each cell (voltage sensitive imaging – so a voltage indicator) with indicators for action potentials (calcium imaging/ calcium indicators) and indicators for all of the different neurotransmitters being released. Basically a real time cartoon where you can visualize every single process going on while the brain is functioning. A cool dream for now.

6. Behavioral tagging of extinction learning Jociane de Carvalho Myskiw, Fernando Benetti, and Iván Izquierdo ; PNAS 2013 (link)

7. Layer-specific excitatory circuits differentially control recurrent network dynamics in the neocortex Riccardo Beltramo, Giulia D’Urso, Marco Dal Maschio, Pasqualina Farisello, Serena Bovetti, Yoanne Clovis, Glenda Lassi, Valter Tucci, Davide De Pietri Tonelli & Tommaso Fellin ; Nature Neuroscience 2013 (link)

This paper looks extremely interesting! I can’t wait to read it!

8. The organization of two new cortical interneuronal circuits Xiaolong Jiang, Guangfu Wang, Alice J Lee, Ruth L Stornetta & J Julius Zhu ; Nature Neuroscience 2013 (link)

This paper also not only looks to be extremely interesting but also appears to be a tour de force of patch clamp recording! Really impressive work!

The next three papers are not “hot off the presses” like the others, but rather papers that came up for one reason or another this week and I wanted to share.

9. Automated whole-cell patch-clamp electrophysiology of neurons in vivo Suhasa B Kodandaramaiah, Giovanni Talei Franzesi, Brian Y Chow, Edward S Boyden & Craig R Forest ; Nature Methods 2012 (link)

This paper is a shout out to someone who means a whole lot to me. You know who you are. I’m very proud of you buddy and can’t wait to hear about the amazing things you are doing!

10. Neural signals of extinction in the inhibitory microcircuit of the ventral midbrain Wei-Xing Pan, Jennifer Brown, & Joshua Tate Dudman ; Nature Neuroscience 2013 (link)

I just briefly heard about this paper in a talk. Looks very good and I especially appreciate the clever use of optogenetics to identify cell type specificity in extracellular recordings.

11. An overview of the tasks used to test working memory in rodents. Dudchenko PA; Neuroscience & Biobehavioral Reviews 2004 (link)

I have been meaning to compile a list of all the different memory tasks and what types of memory they aim to test for a while now. It looks like this paper is going to be perfect!

Hopefully next post will be on time.
