متن کاملDistant cancer effects on standardised testing of peripheral vision.
BACKGROUND Profound central-retinal visual losses have been a major presenting factor reported in cancer and melanoma associated retinopathies (CAR, MAR). However, it is well established that standardised tests of peripheral retinal function are often the most sensitive detectors of early eye disease. This is a preliminary investigation of the responsiveness of the peripheral retina to "distant...
متن کاملCell-Type-Specific Electric Stimulation for Vision Restoration
In this issue of Neuron, Jepson et al. (2014) demonstrate that electric stimulation of primate ON parasol ganglion cells evokes spiking patterns similar to those elicited by visual motion. This work represents progress in the development of cell-type-specific retinal prosthetics for vision restoration.
متن کاملGeometrical and Physical Parameters Affecting Distant Electric Fields Radiated by Lightning Return Strokes
In this paper detailed numerical results are presented for the estimation of the electric field generated by the first return stroke, in order to reproduce the main characteristics of field waveforms measured at distances beyond 50 km. The effect of parameters such as the lightning channel geometry, distance from the source, return-stroke current speed, its attenuation along the channel is disc...
متن کاملSimultaneous Current and Distant Electric Field Waveforms from Upward Lightning: Effect of Ionospheric Reflection
We present simultaneous current and wideband electric field waveforms at 380 km associated with upward flashes initiated from the Säntis Tower. To the best of the authors’ knowledge, the presented dataset in this study includes the first simultaneous records of lightning currents and associated fields featuring ionospheric reflections, and the longest distance at which lightning fields have bee...
