This is a first! An article being reviewed on YouTube in the form of a folk song http://www.youtube.com/watch?v=_6jAWIeu4Bg I think we've found the future of post-publication review.

Lindsay Bremner will be presenting "Driving fast-spiking cells induces gamma rhythm and controls sensory responses". Please RSVP by Tuesday evening if you'd like to attend.
From Lindsay:
"This recent article was one of a pair that used the new technique of optogenetic manipulation to investigate the basis and function of cortical gamma oscillations, which are believed to be crucial for information processing in the brain. The authors test the hypothesis that gamma oscillations are induced by a specific subset of interneurons, and go on to look at the effect of oscillatory phase on the processing of a single sensory input (whisker deflection). I picked the paper because it demonstrates the powerful nature of this new technique for addressing important in vivo network questions, and also because the authors attempt to look at what the oscillations might mean for the processing of real sensory stimuli.

Marie Suver will be presenting a paper describing the response properties of motion-sensitive interneurons in Drosophila using whole-cell patch-clamp recordings. Please RSVP by Tuesday evening if you'd like to attend.
Response properties of motion-sensitive visual interneurons in the lobula plate of Drosophila melanogaster. Joesch M (2008) Curr Biol.Login or register to post commentsWe began with a brief overview of the fly visual system and the Reichardt correlation model. Figure-by-figure, we discussed the author's findings. In general, the group was interested in the technique and how it can help us understand the fly visual system and other computations in the brain. We also discussed what the whole-cell patch prep gains with the addition of behavior. - Marie P.

Mancuso et al. make the point that previously it has been thought that the evolution from dichromat to trichromat "would require evolutionary/developmental changes, in addition to acquiring a third cone type" and that their results demonstrate that "trichromatic colour vision behavior requires nothing more than a third cone type." While this may be possible, given that some females of this species of primate already possess trichromatic color vision, it also seems possible that the species already underwent the evolutionary changes required for the transformation from dichromacy to trichromacy.

If you are new, the CNS Journal Club meets to discuss journal articles that are of interest to the CNS community. We typically meet twice a month on Wednesdays at Noon for lunch and discussion. To be added to the mailing list, please sign up at http://www.klab.caltech.edu/mailman/listinfo/cns-jclub
Gene therapy for red-green colour blindness in adult primates. Mancuso K (2009) Nature.Login or register to post commentsIn this impressive study, Mancuso et al. show they are able to give trichromatic color vision to previously color blind primates using gene therapy. In the species of monkey used in the study, males are red-green color blind while some females have normal trichromatic vision. A virus was used to insert a human L-opsin gene in adult male monkeys missing the L-opsin gene. The inserted L-opsin gene was preferentially expressed in M/L cones. After 20 weeks, the monkey's new color vision was confirmed by both retina recordings and a behavioral test. Interestingly, there was little to no time delay between when expression of the L-opsin was detectable using the retina recordings and when the monkey exhibited behavior indicative of trichromatic color vision. Given this, the authors ... more - John M.
