The VCS test is a measure of one the neurologic functions of vision known as “contrast.” Biotoxins impair the ability to detect subtle contrast within 24-36 hours after exposure. The Shoemaker Protocol™ VCS testing system is an extremely valuable tool to detect and monitor exposure to toxic...
VCSTest.com offers online visual contrast sensitivity (VCS) testing, with printable results, history tracking, and other resources. VCS testing can be used as a screen for exposure to neurotoxins.
But love is not an act of erasure, nor is it simply the inverse of longing.The temptation to see my life in contrast—to say that struggle preceded love, that absence defined its arrival—feels, in some ways, like an illusion.Contrast can make meaning vivid, but it can also distort it...
In contrast, the rot damage found on timbers and beams used in buildings usually develops from the outside-in as water leaking into a structure is more likely to first wet the exterior surface of a structural member than its interior. For this reason, surface inspection and manual probing ...
4.2. Texture boundary contrast measure for the OBTS task simulation In order to compare model performance to perceptual data, the following boundary contrast measure was used:(2)S=μELower-EUpperν+ELower+EUpper+F+50,where μ and ν are constant numbers, and ELower and EUpper are bipole ...
7b, c, no touching response was detected within 15 mm (1.5 s) for R1, which means R1 is a pit. In contrast, diverse voltage signals were detected at 2 mm (0.2 s), 2 mm (0.2 s), and 14 mm (1.4 s) for R2–R4 respectively, indicating that R2 and R3 ...
In contrast to the occipital lobe, when using in-ear EEG recordings during alpha-band SSVEP stimulation, we observe noticeable tendencies towards the 2nd harmonic. This suggests that in-ear sensing could be useful for studying the spatial distribution of harmonics in SSVEP research. Besides, we ...

In contrast, animal eyes efficiently perform visual processes needed for survival with relatively simple and tiny focusing optics, typically comprising one or few lenses. Single lens systems in natural eyes often feature a gradient index (GRIN) profile (Figure 3(g), left). The homogenous index le...
This trend is in contrast to the increased charge densities observed for the smallest electrodes used in this study (see FIG. 11D), which is probably due to an effect restricted to electrodes smaller than ˜10 μm diameter (see above). Representative data from this study (monkey and rat)...
