Sensory systems are complex structures that receive stimuli from the surrounding environment and convert them into interpretable information. In the visual system, light hitting the eye is transmitted to the brain in a way that preserves the spatial conformation of the pictures we see. Retinal...

Patterning the zebrafish visual system requires the actions of Pbx transcription factors, and a downstream growth factor, Gdf6a
DownloadFall 2010
The zebrafish visual system relies on positional information in the retina and optic tectum, so that the spatial fidelity of light signals that enter the eye are preserved for visual processing. This positional information is essential for ordered topographic mapping of retinal ganglion cell...

Photoreceptors (the light-sensitive cellular mediators of vision in the eye) are divided into two classes: rods, which are sensitive to dim light and responsible for vision in low-light conditions, and cones, which are sensitive to specific wavelengths of light, and are responsible for daytime...

Protein prenylation is the post-translational addition of isoprenoid lipid moieties to proteins, which regulates their subcellular localization and function. Farnesyl or geranylgeranyl isoprenoids are covalently linked to cysteines residues in a C-terminal prenylation recognition sequence in...

The roles of Pbx and Meis TALE-class homeodomain transcription factors in vertebrate neural patterning
DownloadFall 2010
One of the major goals of developmental biology is to understand how specialized groups of cells arise from an initially unspecified cell population. The vertebrate hindbrain is transiently segmented along its anterior-posterior axis into lineage-restricted compartments called rhombomeres, making...

Abstract: Numerous reports have concluded that zebrafish (Danio rerio) possesses A(1)-based visual pigments in their rod and cone photoreceptors. In the present study, we investigated the possibility that zebrafish have a paired visual pigment system. We measured the spectral absorption...
