Sentence examples for beginning of fixation from inspiring English sources

The mean activity diverged at the beginning of fixation, according to the preferred direction of gaze.

Exactly the opposite happened when the animal looked leftward: the activity suddenly increased at the beginning of fixation and then decreased after cue onset, achieving also in this case a level comparable to the one the cell had before fixation.

For neurons showing patterns of modulation of gaze and action epoch, which were consistent one to another (Fig. 6A), the separation between the two curves started with the beginning of fixation, as expected, and was maintained all throughout the duration of the task, suggesting that for these neurons the modulation was mainly driven by the gaze signal.

In absolute values, the passive disconjugate drift at the beginning of fixations after the saccade was not big enough to counterbalance the saccade disconjugacy in dyslexic children.

During reading, the eyes perform a stereotyped pattern of vergence adjustment: the saccade disconjugacy is usually divergent and followed by a convergent drift at the beginning of fixations [6], [15], [19].

Generally, the variability of fixation disparity during fixations provides information on the quality of oculomotor vergence adjustments correcting the disconjugacy of the preceding saccade at the beginning of fixations, and afterwards on the quality of the sensory driven feedback loop stabilizing or improving further the vergence adjustment.

A time analysis showed that the disconjugate drift during fixations is high at the beginning of fixations and negligible after about 50 to 100 ms [15], [18]; thus, the oculomotor system overcomes asymmetric pulse-step mismatches first during fixations, whereas after a certain time window such mismatches are resolved and the eyes reach an approximately stable vergence angle.

(2) For the fixation period, we also calculated the disconjugate drift in vergence [6], that is, the change in vergence between the beginning of the fixation period and the minimum fixation disparity (M-E in Figure 1b).

An eye-movement trigger was used to ensure that the video started at the beginning of a fixation.

This result confirms that the phase locking is highly selective for the first spikes in V1 at about 60 ms after the beginning of a fixation.

"When healthy eating becomes a disease in its own right," they conclude, "it is arguably worse than the health problems that began the cycle of fixation".
