Open thread. SFN can be overwhelming, but collectively, we can share what we learned and what we thought was interesting.
So let’s use this thread to post about interesting posters, talks, symposia, and other things.
Hi @thicunha. Yeah, that sounds great. If you’re around on Tuesday, I’ll be presenting my poster between 1-5 PM.
Optogenetic control of Αβ-fibers in acute and chronic pain conditions
http://www.abstractsonline.com/pp8/index.html#!/4071/presentation/14005
Are you or your students presenting anything? I’ll try to come check out.
Hi @achamess I’m already in SFN. I will visit your poster. I also have a poster presentation at the same time. I will be around. regards, Thiago

I really wish I was there to visit your poster! I found it very interesting that according to your abstract with the optogenetic activation you did not see any noxious responses.
Very cool work. I have some questions about it. Did you use L2-L3 DRGs to characterize the co-expression profile? and when you stimulate with light, how deep do you think it goes into the tissue, do you think it goes deep enough to stimulate past the skin?
Hey @lfqueme
Thanks. We used L3-L5, since those DRGs are the major contributors to the paw skin.
It’s possible the light goes deeper. I can’t rule that out, but unlikely given that blue light doesn’t penetrate tissue very much (see this too). Using retrograde labeling I’ve shown that the fibers that terminate in the skin are not proprioceptors (PV+).
