The circadian clock in the retina controls rod-cone coupling.

9 Sep 2008 Although rod and cone photoreceptor cells in the vertebrate retina are anatomically connected or coupled by gap junctions, a type of electrical synapse, rod-cone electrical coupling is thought to be weak. Using tracer labeling and electrical ... Read more...

Mecp2 organizes juvenile social behavior in a sex-specific manner.

7 Jul 2008 Methyl-CpG-binding protein 2 (MeCP2) binds methylated DNA and recruits corepressor proteins to modify chromatin and alter gene transcription. Mutations of the MECP2 gene can cause Rett syndrome, whereas subtle reductions of MeCP2 expression may be ... Read more...

The effect of peripheral visual field loss on representations of space: evidence for distortion and adaptation.

30 May 2008 PURPOSE: To determine whether peripheral field loss (PFL) systematically distorts spatial representations and to determine whether persons with actual PFL show adaptation effects. METHODS: Nine participants with PFL from retinitis pigmentosa (RP) ... Read more...
