To directly compare delayed, non-delayed, and suppressed reaching and grasping movements, we used a slow event-related functional magnetic resonance imaging (fMRI) design.
For the correction of beam-induced movements, we used statistical movie processing as described previously (Bai et al., 2013), with running averages of five movie frames, and a standard deviation of 1 pixel for the translational alignment.
To assess elicited eyelid movements, we used a custom-designed apparatus that delivered a single standardized volume of 20 mL air as a "puff" to the cornea and periorbital region bilaterally at a distance of 3 cm.
DOI: http://dx.doi.org/10.7554/eLife.06462.017 To test whether dynein functionally contributes to chromosome movements, we used multiple inhibition strategies and then assessed the effects on chromosome positioning and segregation.
On return of the baseline questionnaires, we excluded patients if their responses showed that they were no longer dizzy or their dizziness was not aggravated by rapid head movements (we used this item for screening because vestibular rehabilitation is designed primarily to treat dizziness provoked by movement).
To assess whisker movements, we used a geometrical model consisting of three reference points: (i) a point in the medial sagittal line close to the end of the nose, (ii) a point corresponding to the medial angle of the left orbita, and (iii) a point corresponding to the medial angle of the right orbita.
To parse out the effects of average velocity, movement amplitude, and movement duration, we used a design with three groups of participants (a constant-amplitude group, a constant-duration group, and a constant-average-velocity group).
For horizontal eye movement recordings we used the Freiburg MR-Eyetracker system, a fiber-optic limbus tracking device [22].
To further increase the accuracy of the movement correction, we used the beta version of RELION-1.3 to fit linear tracks through the optimal translations for all running averages, and included neighboring particles on the micrograph in these fits.
And we have a better idea of his movements than we used to".
