Cone Electroretinography by Flicker [PDF]
IT is generally assumed that the b-wave of the human retinal action potential is due to the stimulation of the rods. With an intensity of 2,000 lux, the b-waves fuse at a frequency of about 20 flashes per second. At lower intensities the fusion frequency in our experiments decreased.

PROGRESSION OF SCOTOPIC SINGLE-FLASH ELECTRORETINOGRAPHY IN THE STAGES OF CAPN5 VITREORETINOPATHY
Characterization of the degradation of scotopic electroretinography recordings from patients in various stages of autosomal dominant neovascular inflammatory vitreoretinopathy reveals photoreceptors may sustain early insult and reveals a unique time ...

Chromatin remodeling protein HELLS is critical for retinoblastoma tumor initiation and progression. [PDF]
Retinoblastoma is an aggressive childhood cancer of the developing retina that initiates by biallelic RB1 gene inactivation. Tumor progression in retinoblastoma is driven by epigenetics, as retinoblastoma genomes are stable, but the mechanism(s) that ...

WAVELET ANALYSIS OF HUMAN PHOTORECEPTORAL RESPONSE [PDF]
Feature detection of biomedical signals is crucial for deepening our knowledge of the physiological phenomena giving rise to them. To achieve this aim, even if many analytic approaches have been suggested only few are able to deal with signals whose ...
