   Keywords : Dog; ERG; Electroretinography; M L-cones; Retina; S-cones; UV; Ultraviolet; vision;

   Abstract : Although ultraviolet (UV-) sensitivity has long been known to be widespread amonginvertebrates, bi s and some rodents, recent studies have revealed that the ocular media ofmost mammals (unlike man) transmits a large amount of the UV-A wavelengths. In addition torod cells, the domestic dog has two discrete types of cone photoreceptors. READ MORE

3. 2. Evaluation of the retinal ON- and OFF-responses in the dog ERG

   University essay from SLU/Dept. of Clinical Sciences

   Author : Charlotte Kristensson; [2014]
   Keywords : electroretinography; ERG; dog; cones; ON-response; OFF-response; elektroretinografi; hund; tappar; ON-respons; OFF-respons;

   Abstract : The aim of the study was to examine the retinal ON- and OFF-pathways of the canine electroretinogram (ERG). The ON- and OFF-pathways are used to distinguish objects from their backgrounds. A dark object is discernible from a lighter background using the OFFpathway and the ON-pathway is used to descry a light object upon a darker background. READ MORE

   Keywords : Electroretinography; ERG; Cones; S- and M L-cones; dogs;

   Abstract : Full-field flash electroretinography is an electrodiagnostic method used to examine the function of retinal cells. Light stimulation of the eye elicits electrical potentials in the retina. READ MORE
