Genetic dissection of rod and cone pathways in the dark-adapted mouse retina.
A monumental task of the mammalian retina is to encode an enormous range (>10(9)-fold) of light intensities experienced by the animal in natural environments. Retinal neurons carry out this task by dividing labor into many parallel rod and cone synaptic pathways. Here we study the operational plan of various rod- and cone-mediated pathways by analyzing electroretinograms (ERGs), primarily b-wav...
متن کاملRod-cone independence in dark adaptation.
The afterimages visible after cones have recovered in dark adaptation fade against any steady background, but may be revived by a sudden change in the intensity or wavelength of the background. However, when a change of background wavelength is not detectable by rods, it does not revive such an afterimage. showing that sensitivity to cone stimuli has not been affected by bleaching the rods. To ...
متن کاملDark-adapted rod suppression of cone flicker detection: Evaluation of receptoral and postreceptoral interactions.
Dark-adapted rods in the area surrounding a luminance-modulated field can suppress flicker detection. However, the characteristics of the interaction between rods and each of the cone types are unclear. To address this issue, the effect that dark-adapted rods have on specific classes of receptoral and postreceptoral signals was determined by measuring the critical fusion frequencies (CFF) for r...
متن کاملMicrocircuitry of the dark-adapted cat retina: functional architecture of the rod-cone network.
The structure of the rod-cone network in the area centralis of cat retina was studied by reconstruction from serial electron micrographs. About 48 rods converge on each cone via gap junctions between the rod spherules and the basal processes of the cone pedicle. One rod diverges to 2.4 cones through these gap junctions, and each cone connects to 8 other cones, also through gap junctions. A stat...
متن کاملRod-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...
