Flicker VEPs reflecting multiple rod and cone pathways

In an attempt to determine whether the relative contributions of magno-mediated and parvo-mediated inputs to the cortex are significantly altered in the transition from cone to rod vision, VEPs were recorded at different luminance levels (photopic to scotopic) for 2Hz square-wave, isochromatic flicker. The VEP mass response appears capable of reflecting major parvo-mediated contributions even a...

Rod-cone interaction in flicker perimetry.

We have assessed the influence of the rod system on cone flicker sensitivity during flicker perimetry. For temporal frequencies above 18 Hz extrafoveal cone-mediated flicker thresholds for a white test stimulus are as much as 1.5 log units lower when measured against a large background light that saturates the rods than when measured in darkness. Following a Ganzfeld bleach extrafoveal cone fli...

Electroretinographic assessment of rod- and cone-mediated bipolar cell pathways using flicker stimuli in mice

Mouse full-field electroretinograms (ERGs) are dominated by responses of photoreceptors and depolarizing (ON-) bipolar cells, but not much of hyperpolarizing (OFF-) bipolar cells under conventional recording conditions. Here we investigate a novel ERG protocol in mice for functional assessment of the major ON- and OFF-bipolar cell pathways using flicker stimuli for a high luminance with varying...

Lateral suppression of mesopic rod and cone flicker detection.

This study investigated the mechanisms of flicker detection suppression by measuring mesopic rod and cone critical flicker frequencies (CFFs) at different center and surround illuminance levels. Stimuli were generated with a four-primary photostimulator that provided independent control of rod and cone excitations. The results showed that dim surrounds ≤0.2 Td suppressed cone-mediated CFFs at ≥...

Genetic Dissection of Rod and Cone Pathways

45 A monumental task of the mammalian retina is to encode an enormous range (> 10 fold) 46 of light intensities experienced by the animal in the natural environment. Retinal neurons 47 carry out this task by dividing labor into many parallel rod and cone synaptic pathways. 48 Here we study the operational plan of various rod and cone mediated pathways by 49 analyzing electroretinograms (ERGs), ...
