Smooth Pursuit Pursuit is a voluntary response, controlled by attention to moving objects. It is characterized by smooth, conjugate eye movements. Four Functions of Smooth Pursuit. 1) Foveating a moving image to maximize it’s visibility. Ex: Reading a road sign while driving 2) Cancellation of VOR during head tracking.

Generally, DBS ON significantly improved smooth pursuit gains (p = 0.005) and smooth pursuit velocity accuracies (p < 0.001) compared with DBS OFF (Table 2).Moreover, smooth pursuit gains were significantly higher for slower smooth pursuit target velocity movements (p < 0.001). 2020-04-07 2008-12-01 Smooth-pursuit eye movements induced by targets moving at constant velocities (from 5 to 100 deg/sec) were recorded from 13 patients with Alzheimer's disease (AD) and from 11 healthy subjects. Four variables were evaluated to quantify the patients' response to the eye movement tests: (1) Since the smooth pursuit system has its own premotor circuits, a smooth pursuit deficit can be either the result of a premotor smooth pursuit lesion or the consequence of a gaze-holding deficit. To study this question DC eye movement recordings of 52 patients with horizontal gaze-evoked nystagmus and/or smooth pursuit deficits were studied in detail.

Start.

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.

2013-06-24 · Functional imaging studies suggest a widespread activation of a cortico-subcortical network during OKS inducing smooth pursuit eye movements in healthy participants, 24,32 and hemianopia. 33 This network includes the occipitotemporal, parietal, insular and occipital cortex, basal ganglia, cerebellum, and the brain stem.

Visual disturbances are commonly reported in patients with neck pain. Smooth pursuit neck torsion (SPNT) test performed in neutral position and with trunk rotated under the stationary head has been used to discriminate between those with cervical component and those without. However, no studies investigated the reliability of the SPNT-test in patients with chronic neck pain and healthy The smooth-pursuit pathways within the brainstem and cerebellum share much circuity with those that generate vestibular movements. For example, the cerebellar output for smooth pursuit relays in part through the medial vestibular nucleus (MVN) and the adjacent nucleus prepositus hypoglossi (NPH), before reaching the ocular motor nuclei.
