Fluorescence microscopy: Established and emerging methods, experimental strategies, and applications in immunology
(Wiley Subscription Services, Inc., A Wiley Company, 2007-08)
Cutting-edge biophysical technologies including total internal reflection fluorescence microscopy, single molecule fluorescence, single channel opening events, fluorescence resonance energy transfer, high-speed exposures, ...
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) ...
Glutamate as a neuron-to-glial signal for mitogenesis: role of glial receptors
(Elsevier, 1993-06-11)
The presence on glial cells of receptors for neurotransmitters suggests the capability of neuron-to-glial signalling. Here, we asked whether the retinal transmitter, glutamate, may serve as a mitogenic signal for human ...
Apparently new syndrome of sensorineural hearing loss, retinal pigment epithelium lesions, and discolored teeth
(John Wiley & Sons, Inc., 1998-01-06)
We report on a family with early-onset sensorineural hearing loss, abnormal retinal pigment epithelium granularity, accumulation of creamy-white lesions at the level of the retinal pigment epithelium particularly superior ...
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 ...
Membrane Polarity of the Na+-K+ Pump in Primary Cultures of Xenopus Retinal Pigment Epithelium
(Elsevier, 1994-11)
The retinal pigment epithelium is a transporting epithelium that helps regulate the volume and composition of the subretinal space surrounding photoreceptor outer segments. The capacity of the RPE to actively transport Na+ ...
