Sentences with phrase «saccade amplitude»

Hence, these results indicate that, just like the saccade velocity profiles, the skewness of the bursts increases systematically with saccade amplitude (and duration).

Note that for a given saccade amplitude the burst profiles along the rostral - to - caudal extent of the SC appear to have very similar shapes, which change systematically as function of saccade amplitude (and duration).

More specifically, peak firing rates in the recruited population decrease systematically with increasing saccade amplitude while burst duration and skewness increase with increasing saccade amplitude.

Individual trials are sorted according to saccade amplitude and direction, respectively.

Nevertheless, the burst properties reported in this study strongly support the idea that the deeper layers of the SC act as an optimal controller: the systematic organization of peak firing rates and burst durations as function of saccade amplitude along the motor map, the synchronous change in firing rate of recruited cells in the population, and the shaping of the temporal burst profile of a given cell with the currently planned saccade, all contribute to the generation of straight eye - movement trajectories with optimal kinematics.

This movement - field plot shows that the number of spikes in the burst (color code) varies systematically with saccade amplitude and direction.

«These finding suggest that assessing the ability of people to adapt saccade amplitudes is one way to determine whether this function of the cerebellum is altered in ASD,» said Edward Freedman, Ph.D. an associate professor in the URMC Department of Neuroscience and co-author of the study.

Not exact matches

This analysis shows that the peak firing rate occurs at about the same instant relative to saccade onset (see Table 1, for further quantification) while the burst duration increases systematically with the preferred amplitude of the cells (indexed by the gray - scaling).

We first examined the temporal discharge profiles of saccade - related neurons along the rostral - to - caudal extent of the SC for saccades of five particular amplitudes.

We chose two cells from the central region of the SC (preferred amplitudes 9.5 ° and 13.5 °, respectively) because these cells fired vigorous bursts for saccades with distinctly different kinematics.

For both cells, peak firing rates occurred at about the same instant relative to movement onset regardless of the movement amplitude, but burst durations were shorter and peak firing rates were higher when the cell took part in the small saccades than when it participated in the large saccades.
