Example Sentences:
(1) Electrophysiological recording methods were applied to the isolated, retina-eyecup preparation of the rabbit.
(2) In order to test the hypothesis that melatonin and dopamine may be involved in the regulation of cone movement, we have used an in vitro eyecup preparation from Xenopus laevis that sustains light- and dark-adaptive cone retinomotor movement.
(3) The electroretinogram (ERG) and single-unit ganglion cell activity were recorded from the eyecup of the skate (Raja erinacea and R. oscellata), and the adaptation properties of both types of response compared with in situ rhodopsin measurements obtained by fundus reflectometry.
(4) The extent of regeneration was graded with the quantities of IRBP and opsin introduced into the RPE-eyecup.
(5) We studied the role of the cytoskeleton in this process by first quantifying OS membrane assembly in rods from explanted Xenopus eyecups with a video assay for disc morphogenesis and then determining if the rate of assembly was reduced after drug disassembly of either MTs or F actin.
(6) Intracellular recordings were obtained from horizontal cells in the superfused retina-eyecup preparation of the rabbit.
(7) Laser micromass analysis was used to investigate the effect of light on the Ca content of rod outer segments in the isolated retina and eyecup of the toad, Bufo marinus.
(8) Using eyecups from both Xenopus laevis and Rana pipiens, we found that kainate, quisqualate, and N-methyl-D-aspartate (NMDA) were all neurotoxic, but that kainate caused a more extensive inner retinal lesion.
(9) Whole-cell recordings of amacrine and ganglion cells in the superfused retina-eyecup preparation of the mudpuppy were obtained in order to determine which excitatory amino acid receptor (EAAR) subtype mediates the synaptic responses of these neurons.
(10) Recoveries of 98-100% were obtained from tissue samples by internal addition for the retinoids tested (retinol, retinal and retinyl palmitate); and the absolute recovery of endogenous retinal from rat eyecups was confirmed by spectrophotometric measurements of rhodopsin.
(11) Synaptic transfer between the retinal input and output was studied in turtle eyecups by injecting rectangular current pulses into a single cone or rod while recording externally from a ganglion cell.2.
(12) The spectral sensitivity of the ERG to flicker in the light-adapted eyecup preparation was shifted to longer wavelengths; it peaked at around 550 nm.
(13) Simultaneous intracellular horizontal cell and extracellular ganglion cell recordings were obtained from a superfused in vitro rabbit eyecup preparation and the effects of bath applied drugs on these cells' light responses observed.
(14) The vitreal surface of the retina in each eyecup was washed sequentially with 1% Triton X-100, water, and culture medium.
(15) In the eyecup preparation nearly identical time-courses were evoked only after perfusion of the vitreous surface with solution having high (Mg(++)).
(16) Extracellular electrophysiological recordings were obtained from rabbit retinal ganglion cells in either a superfused eyecup or an in vivo preparation.
(17) The directional selectivity of amacrine and ganglion cells was studied using conventional intracellular recording techniques and drug application in the superfused retina-eyecup preparation of the tiger salamander.
(18) The shedding of rod outer segment disc membrane was investigated in a commonly used frog eyecup preparation, with respect to length of time in vitro.
(19) Rod outer segments (ROS) or neural retinas were isolated and bleached, then incubated with native RPE (RPE-eyecup) in the presence or absence of IRBP.
(20) The influence of horizontal cells on ganglion cells, the output neuron of the retina, was examined in an in vitro rabbit eyecup preparation.
