Smooth pursuit causes higher than expected VOR responses during slower head movements (< 1.0 Hz)41,54,55 ⇓ ⇓ but not during more rapid head turning (>2.0 Hz).56,57 ⇓ Because of this, AHR testing can be done in the light with the eyes open if the head movement is 2.0 Hz or more.

As a subsidiary experiment, we compared pursuit performance against that of fixation. Methods: Eye position was recorded from 15 observers during pursuit. The

Advanced Smooth pursuit is asymmetric: most humans and primates tend to be better at horizontal than vertical smooth pursuit, as defined by their ability to pursue smoothly without making catch-up saccades. Most humans are also better at downward than upward pursuit. Pursuit is modified by ongoing visual feedback. Smooth pursuit is evaluated for symmetry (the difference between rightward and leftward scores) and gain (eye velocity versus target velocity). Analysis criteria take into consideration significant age and gender effects.

Smooth pursuit 4. 1998-02-01 In smooth pursuit tracking, the patient is instructed to follow a sinusoidal moving target with his or her eyes only. The target can be a pendulum, metronome, or computer-generated stimulus. Article.

Smooth pursuit is evaluated for symmetry (the difference between rightward and leftward scores) and gain (eye velocity versus target velocity). Testing Smooth Pursuit with our iVNG, the patient is instructed to follow the stimulus using only the eyes and not move the head as the stimulus moved back and forth across the projected area.

Thecalcula-tion of smooth pursuit gain was made from the chart (speed ofthe chartpaper 10 mm/s). Furthermore, an index of asymmetry of Smooth pursuit eye movement. This experiment focuses on the effect of visual motion direction (leftward and rightward) on smooth pursuit initiation. Figure 1 shows representative eye velocity and acceleration traces during step‐ramp tracking (ramp velocity = 18.5 deg/sec) to the leftward and rightward directions.

The change with stimulus frequency in the phase of horizontal smooth pursuit velocity modulation was small but significant (F 1.59,286.81 = 5.38, p = 0.009), with the modulation of smooth pursuit velocity tending to lag that of the target velocity as the stimulus frequency increased . 2013-05-29 · In smooth pursuit eye movements, the response to a brief perturbation of target motion is larger during pursuit of a moving target than during fixation of a stationary target. As a step toward identifying the locus and mechanism of gain modulation, we test whether it acts on signals that are in visual or motor coordinates. Smooth pursuit eye-tracking dysfunction (ETD) is a biological marker for schizophrenia.
