Micromechanical experiments with 3 × 3 × 6 μm3 sized micro pillars were used to examine orientation dependencies of the mechanical properties in a severely plastically deformed high strength steel and compared with the undeformed state.
One study examined orientation selectivity at different contrasts in the primate [26] but did not explicitly report interactions between orientation tuning and contrast.
We performed extracellular recordings and examined orientation tuning of single-units using static sine-wave gratings that were flashed for 200 msec.
We also examined orientation selectivity and the effects of contrast on orientation tuning with respect to the layers in which recordings were obtained (n = 94 single-units, 74 orientation selective, 20 not orientation selective).
It was designed to tease apart the effects of contrast from those of contrast adaptation on orientation tuning, while at the same time providing the possibility to examine orientation tuning for a stimulation duration comparable to that of a visual fixation.
Obermayer and Blasdel (1993, 1997) examined orientation pinwheel locations in macaque monkey visual cortex, comparing Fourier spectra of orientation pinwheel locations with spectra produced by regular hexagonal and square lattices.
An alternative way to examine the implication of parvo- and magnocellular inputs on the effects of contrast on orientation tuning would be to examine orientation-tuning dynamics.
We first verified that Vang and fz act non-autonomously in the developing notum by examining the orientation of dividing wild-type SOPs that are in contact with either Vang mutant cells or fz RNAi) cells with strongly decreased fz activity.
The inversion can best be visualized at the molecular level by examining the orientation of the att (attachment) sites that flank the ends of these phages.
