چکیده
Field sensitivities were measured under conditions of Mand L-cone isolation for seven infants (8–12 weeks-old) and two adults, using silent-substitution and the visually evoked potential (VEP). The efficacy of the receptor-isolation conditions were first verified by measuring psychophysical and VEP-derived action spectra from two color-normal adults under conditions of Mand L-cone isolation. Mand L-cone action spectra obtained from the two methods were found to be similar to the Smith and Pokorny Mand L-cone fundamentals, respectively. The VEP-derived action spectra obtained from infants and adults were well fit by the Smith and Pokorny Mand L-cone fundamentals. These data, in conjunction with our previous study, confirm that Mand L-cones are operating by 8 weeks and possibly as early as 4 weeks of age. © 1998 Elsevier Science Ltd. All rights reserved.

متن کاملImpaired Retinal Function in Young Labrador Retriever Dogs Heterozygous for Late Onset Rod-Cone Degeneration
Xenon-flash d.c.-electroretinograms were recorded from dark adapted, rod-cone degenerate homozygote affected (n = 6), heterozygote carrier (n = 3) and control retinas (n = 4) at 3 and 4 months of age, starting at 0.6 log units below control PII threshold. One log unit higher stimuli were necessary to evoke PII in heterozygote and affected retinas compared to controls. Unique to the heterozygote...
متن کاملDetecting saccades with jerk
In studies of smooth eye movements, saccades are often detected and removed from eye movement records during analysis. A simple and effective method for saccade detection is described; the method uses jerk (the third derivative of eye position with respect to time).

Twelve participants were trained to be experts at identifying a set of ‘Greebles’, novel objects that, like faces, all share a common spatial configuration. Tests comparing expert with novice performance revealed: (1) a surprising mix of generalizability and specificity in expert object recognition processes; and (2) that expertise is a multi-faceted phenomenon, neither adequately described by ...
متن کاملA quantitative estimate of flash-induced Ca2+- and Na+-influx and Na+/Ca2+-exchange in blowfly calliphora photoreceptors
The flash-induced Ca(2+)- and Na(+)-influx and Na+/Ca(2+)-exchange activity in blowfly Calliphora photoreceptors were investigated. The change in membrane potential, induced by a bright flash, was intracellularly measured in vivo. Based on a biophysical photoreceptor model, the Na(+)- and Ca(2+)-currents and concentration changes were determined from the first transient depolarization phase of ...
