Ganglion cell acuity in hooded rats
(Elsevier, 1982)
Previous measurements of retinal ganglion cell acuity in hooded rats have differed significantly from behavioral tests of visual acuity. One possible source of this discrepancy is examined--that light deprivation in early ...
Interactions of the horizontal and vertical human oculomotor systems: The saccadic systems
(Elsevier, 1972-01)
The human oculomotor system has been studied by numerous people for well over half a century. Since the visual system is our primary sensory input channel, it is important for us to know how information is processed by the ...
Static and dynamic responses of slowly adapting joint receptors
(Elsevier, 1974-04-19)
1. (1) A systems analysis approach was used to study slowly adapting knee joint receptors. Transfer functions were obtained from the receptor response to sinusoidal inputs of knee joint angle over a range of frequencies ...
Multichannel semiconductor-based electrodes for in vivo electrochemical and electrophysiological studies in rat CNS
(Elsevier, 1990-12-11)
Five-channel silicon-based microprobes were sputter-coated with carbon, coated with Nafion, and used for both in vivo electrochemical and single-unit electrophysiological recordings. High-speed electrochemical studies were ...
Extrinsic current and flash sensitivity in turtle cones
(Elsevier, 1994-02)
The effects of hyperpolarizing current and background light on intracellular responses of red cones in turtle were compared. Even though a background light always reduced response amplitude, hyperpolarizing current did so ...
Flicker fusion characteristics of rod photoreceptors in the toad
(Elsevier, 1983)
Critical fusion frequency (CFF) of toad rods was examined at various intensities using intracellular recordings. Data were compared to CFF measurements (as a function of intensity) obtained with the electroretinogram (ERG) ...
Relative modulation sensitivities of the red and green color mechanisms
(Elsevier, 1978)
The sensitivities of the human green and red cone mechanisms to sinusiodally flickering light were found to be near equal and independent of field size and estimation method. No wavelength dependency of modulation sensitivity ...
Depth of focus, eye size and visual acuity
(Elsevier, 1980)
We develop formulas for calculating the approximate depth of focus of any eye. They show that the magnitude of depth of focus is inversely proportional to the size of the eye and to its visual acuity. One particular ...
Evidence for a power law intensity code in the coupled cones of the turtle
(Elsevier, 1990)
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 ...
