MOTION SENSITIVITY IN THE VISUAL-SYSTEM OF PIGEON AND FLYWolfoberhollenzer, FKirschfeld, K
Dynamic visual acuity (DVA) may be a useful indicator of the function of the vestibulo-ocular reflex (VOR) but most DVA tests involve active head motion in the yaw plane. During gait the passive, vertical VOR may be more relevant and passive testing would be less likely to elicit compensato...
The effects of V4, MT, and combined V4+MT lesions were assessed on a broad range of visual capacities that included measures of contrast sensitivity, wavel... Peter,H.,Schiller - 《Visual Neuroscience》 被引量: 341发表: 1993年 Motion Perception following Lesions of the Superior Temporal Sulcu...
using the 4 motion structures illustrated in Fig.1A: independent (I), global (G), clustered (C), and hierarchical (H) motion. In the case of independent motion, there are no correlations between the dots’ velocities. The independence is characterized in the graph structure (gray background...
Patients deprived of visual experience during infancy by dense bilateral congenital cataracts later show marked deficits in the perception of global motion (dorsal visual stream) and global form (ventral visual stream). We expected that they would also show marked deficits in sensitivity to biological...
To test this synaptic connection functionally, we blocked LPi4-3 cells and imaged calcium responses in T4/T5c terminals. Interestingly, motion-opponent suppression was still present in LPi block flies; however, it was substantially reduced compared to controls, as in the experiments in VS and ...
CHART FOR TESTING VISUAL ACUITY AND/OR SENSITIVITY TO SPATIAL CONTRASTS OF A MAN, DEVICE FOR TESTING, AND PROCESS FOR THE MANUFACTURE THEREOF the present invention relates to a test equipment of acuity, contrast sensitivity, and / or in the space, a device and a process for the manufacture ...
Furthermore, the literature suggests that global motion perception is a higher-order function, and there is clear segregation between global motion sensitivity and static forms [37]. We also hypothesized that the observed greater EM activity in DT may result from a delayed response to a stimulus,...
(Tarkiainen et al., 1999;Salmelin, 2007). But Dikker and colleagues themselves do not test or demonstrate sensitivity to low-level features like word length. InDikker et al. (2009,2010) there were large differences between word types in average word length, but in neither of the ...
Retinal prostheses could restore image-forming vision in conditions of photoreceptor degeneration. However, contrast sensitivity and visual acuity are often insufficient. Here we report the performance, in mice and monkeys with induced photoreceptor degeneration, of subretinally implanted gold-nanoparticle-coa...
