Sentence examples for fixation baseline from inspiring English sources

Patients in both groups were presented with four series of four pictures (1.5 s each) per category in pseudorandom order with alternating presentation and fixation baseline blocks.
To investigate this issue, we used a paradigm that included a fixation baseline and could distinguish between the two types of revDMs (aF vs. dR).
One of these conditions was a fixation baseline (nothing was visible but the fixation point).
The flashed texture was presented during every condition, including the fixation baseline.
In separate GLM analyses, we contrasted all five Gabor conditions to the fixation baseline.
We measured activity changes induced by a foveally presented letter stream relative to a preceding fixation baseline.
Each run comprised of experimental blocks (10 trials of a single condition) lasting 32.8 sec each (14 volumes) interleaved with 18.7 seconds of rest (fixation baseline, 8 volumes).

The pattern stimuli were presented repeatedly in blocks of 20.8 seconds with a presentation time of 500 ms and an inter-stimulus-interval of 540 ms. Each stimulus block was presented twice with randomized sequence and a 20.8 second fixation-only baseline between blocks.
The following contrasts were used for sustained activity effects: 1) Common = Money > Fixation, Money > Baseline, Liquid > Fixation, and Liquid > Baseline; 2) Money-Selective = Money > Fixation, Money > Baseline, and Money > Liquid; 3) Liquid Selective = Liquid > Fixation, Liquid> Baseline, and Liquid > Money.
