The use of silent substitution in measuring isolated cone- & rod- human electroretinograms. An electrophysiological study of human rod- and cone- photoreceptor activity derived using silent substitution paradigm
After over a decade of its discovery, the Electroretinogram (ERG) still remains the objective tool that is conventionally used in assessment of retinal function in health and disease. Although there is ongoing research in developing ERG- recording techniques, interpretation and clinical …

An electrophysiological study of chromatic processing in the human visual system. Using visual evoked potentials and electroretinograms to study cortical and retinal contributions to human trichromatic vision.
… at the retinal level was examined using the electroretinograms (ERGs) for which cone isolating stimuli were used to assess the nature of L and M cone inputs to cone-opponent mechanisms. The results from the VEP experiments suggest VEP morphology is dependent upon 1) chromatic and or luminance …

Modelling saposin deficiency in Drosophila: progressive neurodegeneration, storage and physiological decline
… deterioration in phototransduction, measured by electroretinograms. In addition to nervous system pathology, dSap-r mutants also exhibited an abdominal swelling phenotype that may be related to their abnormal Malpighian (renal) tubules and may, therefore, represent an osmoregulatory defect. Both …

The maculoprotective effect of a thiol antioxidant in retinal degeneration models
… reduction in visual function, as determined from electroretinograms (ERG) recorded 36 hours after NaIO3 injection. Other toxic effects were observed at a later time point after NaIO₃ injection: increased lipid peroxidation (as measured by formation of 4-hydroxynonenal, 4-HNE), elevated cysteine …

Cannabinoids: A Novel Treatment Strategy for Retinal Neurodegenerative Disorders
… mM) and O-2545 (2mM) were co-injected with NMDA. Electroretinograms (ERG) were recorded at baseline, 1 wk and 2 wk after injection. Contralateral normal eyes served as controls. After 2 wk, retinas were flat mounted and stained with H&E.</p> <p>While both O-compounds showed significant IOP …

The Effect of SSRIs on Adult Human Visual Cortex Plasticity. Do SSRIs Affect learning?
… therapy. Visual acuity (VA), stereopsis, electroretinograms and visual evoked potentials (VEPs) were measured fortnightly. The third experiment was a case study in which one participant with amblyopia completed two sessions of binocular training, one with placebo and the other with …

Gene therapy provides long-term visual function in a pre-clinical model of retinitis pigmentosa
… are affected in human RP patients. We also used electroretinograms (ERGs) to measure both photoreceptor-specific and global retinal visual function in the Pde6anmf363 mice. For our gene therapy experiments, we utilized a vector with the cell-type-specific rhodopsin (RHO) promoter: …

MICROELECTRODE ARRAY FOR CAPACITIVE TRANSDUCTION OF RETINAL RESPONSES
… and capacitive configurations of the device. Electroretinograms (ERGs) were recorded and the overall performance of the device was analyzed. The devices showed good consistency across all 60 Pt electrode clusters during characterization and when interfaced with retinal tissue. ERGs were …

Mild Traumatic Brain Injury with Associated Visual System Dysfunction: Investigating Histopathology, Functional Correlates, and a Novel Therapeutic Immune Modulator
… was completely rescued with drug treatment. Electroretinograms were run both pre- and post-blast on mice to obtain an electrophysiological readout of retinal cellular function over the first month after blast. The left eye of 50V animals showed a pathologic B-wave elevation, but no change in …
