The Organization of the Retina and Visual System
There is a new publication out in the Journal of Neuroscience (cover story) from Moran Eye Center scientists, Store-Operated Calcium Entry In Müller Glia Is Controlled By Synergistic Activation Of TRPC And Orai Channels authored by Tünde Molnár, Oleg Yarishkin, Peter Barabas, Anthony Iuso, Bryan William Jones, Robert Marc, Tam Phuong, and David Krizaj.
This *very cool* paper in The Journal of Physiology (also featured in the F1000) by authors Tünde Molnar, Peter Barabas, Lutz Birnbaumer, Claudio Punzo, Vladimir Kefalov and David Krizaj examines mechanisms of cytosolic calcium levels in rod photoreceptor cells.

Simonis, Britt Dubil, Tadashi Miya, Paul R. Olson, Kortnie Walker, Bonnie Archer, Peter Barabas, David Krizaj, Gou Young Koh, Guangping Gao and Balamurali K. Ambati.

This paper by Peter Barabas, Wei Huang, Hui Chen, Christopher L. Koehler, Gareth Howell, Simon W.M. John, Ning Tian, René C Rentería and David Križaj is an outcome of an attempt to follow glaucoma progression in the DBA/2J mouse model of a naturally occurring, late onset form of glaucoma. Ideally, a non-invasive technique should be used and in this case, they used a device to take advantage of the optomotor head turning reflex to assess progressive loss of vision. This reflex is very similar to the involuntary rotation of the eye in response to a rotating visual stimulus and it is present in all animals from fish to mammals (including humans). Interestingly, the DBA/2J strain was found to utterly lack this reflex.

ARVO 2011 has come and gone. Its taken me a couple of weeks to get through the post ARVO chaos and get caught up on my own work before posting some of the snapshots, but here they are. If you’d like to post your snapshots from ARVO here, send me an email (webvision@hsc.utah.edu) and we’ll arrange to add them to the list and credit you appropriately.
