Furthermore, it also sometimes happened that, for a given single-unit, response amplitude obtained with stationary stimuli at different contrasts differed from that expected from the CRFs obtained with drifting gratings).
Student's t test of JMP 8.0.2 was performed to test the significant difference between different contrasts.
Differences in mean rCBF in different contrasts (Post minus Pre2, Pre2 minus Pre1) were analysed by one-tailed t tests.
I hypothesised that the two methods under study would differ in their sensitivity to recover these known SA differences between two conditions in different contrasts.
However, contrast adaptation did reduce the difference in orientation tuning observed between different contrasts, indicating that contrast adaptation does contribute to making orientation tuning less contrast-dependent.
We report results from all these ROIs to show the similarity and differences of our results across the different contrasts and data used to define these ROIs.
Changes in RURA were calculated as RURAC2−RURAC1, with C1 and C2 two different contrasts (C1
The various grades yield prints of a normal tone range from negatives of different contrasts: a soft paper grade for a high-contrast negative, a normal paper for a normal negative, a hard paper for soft negatives, and so on.
And while Tétu's remit is naturally more focused, and, she acknowledges, "not so exotic", the aim was still to show the "different contrasts" of the Morbihan region: "the coast is very rich and in the middle, it's very rural.
And these different contrasts may induce different effects.
These different designs lead to the use of different contrasts.
