Bar-like S-cone stimuli reveal the importance of an intermediate temporal filter

Abstract: 1The relative involvement of different temporal frequency-selective filters underlying detection of chromatic stimuli were studied. Diverse spectral stimuli were used, namely flashed blue and yellow light spots, wide bars and narrow bars. The stimuli were temporally modulated in luminance having constant wavelength. Although the bar-like stimuli apparently reduced the sensitivity at short and long wavelengths, the cone-opponent mechanism still remained responsible for the actual stimulus detection at different… Show more

“…Impairments in motion processing efficiency may be due to neural cell loss, neurotransmitter changes, lipofuscin accumulation, and degeneration of myelin and cells. 39,45,46 Several studies suggest that multiple speed-tuned globalmotion systems process motion at different speeds, 16,47,48 and the present study also supports this finding. Almost all MT neurons are selective for a limited speed range.…”

“…Typically, recurrence leads to explicit or emergent forms o f m em ory (M aex & Steuber, 2009), but even purely bottom-up visual models will have m em ory effects if they have multi-scale temporal filters (e.g., Baraas, Kulikowski, & M uldoon, 2010). Memory is unavoidable in any physical process that takes real time to com plete.…”
