ROIs were defined both functionally and anatomically based on the regions showing negative activity on the all tasks-versus-fixation contrast.
On the other hand, the results also suggest that streams from the frontal to visual regions may not be exclusive for orienting and they also appear during fixation, in contrast to those from the frontal to parietal regions.
Paraformaldehyde fixation, in contrast, better preserved staining of intracellular structures (Fig 6B).
In addition, other Leptospirillum species [ 4, 24] are reportedly capable of nitrogen fixation, in contrast to L. ferriphilum, making extrapolation from one species to another difficult.
Transpedicular screw fixation, in contrast, provides higher mechanical stability [ 13, 21] and showed higher pull-out strength in biomechanical studies (1,214 677 N for pedicle versus 355-332 N for lateral mass screws in the subaxial cervical spine) [ 6, 7] and less loosening in fatigue analyses [ 7, 14].
> As shown in Figure 2, each of the four baseline contrasts (words > fixation, pseudowords > fixation, line strings > fixation, Hebrew strings > fixation) resulted in activation of a similar bilateral task-positive network.
We provided a detailed description of the fixation and contrasting protocol in the Methods section.
Mr. Kaiser's determination to attend any event that can conceivably build relationships with artists, donors, board members, diplomats and politicians, and his fixation with detail, contrast sharply with Mr. Domingo's episodic involvement.
b In contrast, fixation by glutaraldehyde solution including cupromeronic blue (CMB) shows that numerous braces of proteoglycans are recognized on the surface of cell projections and within the basal lamina (arrow head) of epithelial stem cells.
The task was the detection of a luminance change of the fixation point (luminance contrast after change: 53.4%).
