The Effects of Target Velocity and Duration on Horizontal Smooth Pursuit Eye-Tracking in Normal Subjects, Rewarded and Non-Rewarded Schizophrenics.
In the human retina the rods and cones are unevenly distributed, with the greatest density of photoreceptors being located at the fovea. A perceptual correlate of this anatomical distribution is that visual acuity (a measure of spatial resolution) is greatest at the fovea. Accordingly, one function …

Comparing Differentiated Rod And Cone Transcriptomes Reveals Rax As A Controller Of A Defined Cone Gene Regulatory Program
<b>Purpose</b><br></br>Rods and cones convert light stimuli into signaling information for brain- mediated visual perception. Specific gene mutations primarily affecting both photoreceptor (PRs) types lead to retinal dystrophies, including rod-cone (retinitis pigmentosa) and cone-rod degeneration. …

Role of DeltaC and DeltaD in Zebrafish Retinal Development
… the specific roles of different Delta ligands on retinal development are not well characterized. The focus of this study was to investigate the specific functions of the Delta ligands, deltaC (Dlc) and deltaD (Dld), in zebrafish retinal development by using dlcb663 and dldtg249 mutant …

A Comprehensive Framework for Adaptive Optics Scanning Light Ophthalmoscope Image Analysis
<p>Diagnosis, prognosis, and treatment of many ocular and neurodegenerative diseases, including achromatopsia (ACHM), require the visualization of microscopic structures in the eye. The development of adaptive optics ophthalmic imaging systems has made high resolution visualization of ocular …

The Isolation of Human Rod and Cone Photoreceptor Activity combining Electroretinography and Silent Substitution Techniques
… used to independently assess the function of rod and cone photoreceptors within the human retina. The work in this thesis sought to investigate an alternative method of recording the ERG, using the silent substitution paradigm (Estevez and Spekreijse 1982). The aims are separated into two parts, …
