dc.description.abstract | The hyperpolarizing responses to light were recorded intracellularly from red cones of the turtle, Pseudemys scripta elegans. Pairs of slit stimuli were flashed alone or together at various intensities, one slit positioned on the receptive field center and the other displaced 30 [mu]m. The peak amplitude of the response was measured, and the results analyzed to quantify the relationship between the light intensity and the size of the neural signal evoked prior to the spatial interactions occurring in the network of coupled cones. This signal, E, was found to be described by a compressive power law, E = k [middle dot] I0.5, where I is slit intensity. Evidence that the inferred excitation function describes a local mechanism independent of the slit position was obtained by measuring the response and the sensitivity receptive field profiles. The response and the sensitivity fields both decreased exponentially, but with space constants that differed by a factor of two, indicating in still another way the existence of an early square-root transformation. | en_US |
