Target velocity = 20/s; Initial target exposure duration (PD) = 150 ms. (B) The difference signal averaged across all six subjects for PD = 150 ms for each target velocity [5 (red), 10 (green), 15 (magenta), and 20/s (blue)]. II. Cortex 19, 11861197. B., and Heinen, S. J. Time-advanced neuronal activity has also been observed in FEF and SEF (Fukushima et al., 2002) during predictive pursuit of sinusoidal target motion. The release of the output from MEM is dependent on timing that can be derived from external cues (Boman and Hotson, 1988; Barnes and Donelan, 1999; Jarrett and Barnes, 2005) or cues derived from the motion itself if it is periodic (Barnes and Asselman, 1991). PubMed Central Tanaka, M., and Lisberger, S. G. (2001). Smooth-pursuit eye movements support scrutiny of objects moving in space by matching eye velocity to target velocity in order to both reduce retinal blur of the moving object and facilitate its continued foveation. The latencies in all directions were not significantly different between left (127.1798.53ms in all directions) and right (137.14104.80ms in all directions) eyes (P>0.21, Wilcoxon signed-rank test with Bonferroni correction; Fig. Technol. Neurol. (2005) examined the postnatal development of the Purkinje layer in the mouse cerebellum and showed that the oculomotor vermis belongs to the latest developing cerebellar cortical structures. During the time that the eye is fixated, new information is brought . We present a case of a male member of the Indiana Kindred with supranuclear palsy, an uncommon feature in GSS. J. Vis. Automatic recording of the target location during smooth pursuit eye movement testing using video-oculography and deep learning-based object detection. The earlier studies reported that the paralystic strabismus mixes with saccade in SPEM25,26. This indicates that the acquisition of working memory and the appearance of the initial smooth-pursuit before saccades in this task are separate processes (Figures 6B1,B2; see section Parkinson's Disease); the latter required further training for efficient and nearly automatic tracking performance. 91, 13141326. Adapted from Schweigart et al. Figure 9. Biol. 8600 Rockville Pike Hasegawa, R. P., Peterson, B. W., and Goldberg, M. E. (2004). The separated data were decomposed into horizontal (C) and vertical (D) components from the position vector. A smooth pursuit is a controlled and guided movement of both eyes on a moving target. 80, 7184. Fukushima, J., Akao, T., Kurkin, S., Kaneko, C. R. S., and Fukushima, K. (2006). Brain Res. (Lond.) 10, 97129. Brain Res. It was argued that subtraction of the Short-ramp response (Figure 3D) from the Mid-ramp response (see Figure 4A) should give an indication of the temporal development of the expectation-dependent extra-retinal component. MSTl), sustained firing here may, in fact, be dependent on ongoing eye movement. Our hypothesis is that active pursuit of a single target in the simple ramp task is achieved by augmentation of gain for the selected target by increasing open-loop gain (wT1) in the indirect pathway and concomitantly initiating extra-retinal activity in the efference copy loop (i.e., increasing 1). Smooth-pursuit initiation in the presence of a textured background in monkey. Bennett, S. J., and Barnes, G. R. (2003). The target location and both eye positions at the peak time were defined as maximum values. We determined the differences in the latencies and gains within both eyes in each direction using the Schffe test. After excluding 1s from both ends of the separated data (black vertical lines in C and D), the medians of the horizontal and vertical target locations were calculated and plotted (E). (1992). The latencies in the lower left (533.33ms), lower right (633.33ms), and lower (233.33ms) areas of the nondominant eye were prolonged in comparison to those of the dominant eye (lower left, 266.67ms; lower right, 66.67ms; lower, 66.67ms).

The green, blue, and red lines indicate the target location, left eye position, and right eye position, respectively. Similar modulation of spot motion responses during the action period by cues was also observed in visual motion responses of some caudal FEF pursuit neurons (Figures 2FI of Fukushima et al., 2011b). The onset of activity reduction coincided with the onset of smooth pursuit. J. Physiol. For example, the effects of chemical inactivation of FEF (Fukushima et al., 2011a,b) suggest an association between timing and velocity of the memory-based pursuit response and the gain and phase error of sinusoidal pursuit. Britten, K. H., Newsome, W. T., Shadlen, M. N., Celebrini, S., and Movshon, J. To obtain No significant difference between the two areas was detected in other periods including the delay 2 of go trials where movement-preparation is required. The latter generates smooth movement scaled to the eccentricity and in the direction of the shift (Grsser, 1986; Sheliga et al., 1994; Barnes et al., 1995). Pursuit system purpose. While it is possible to consciously carry out this action in the presence of a stimulus, very few people can move their eyes in this way without something to focus on. The remembered pursuit task: evidence for segregation of timing and velocity storage in predictive oculomotor control. (2002). Sheliga, B. M., Riggio, L., and Rizzolatti, G. (1994). Second, to evaluate these results, we calculated choice probability (Britten et al., 1996) and its time course based on whether the monkeys pursued in the preferred direction of the neuron (tested by 100% correlation) or anti-preferred direction. Neuropsychology 22, 585595. An fMRI study of anticipation and learning of smooth pursuit eye movements in humans. Kwon, K. A. et al. Google Scholar. In this study, we used the VOG-SSD system developed by Hirota et al.17 We recorded eye movements while tracking the target using a VOG (EMR-9, NAC Image Technology Inc., Tokyo, Japan). Nat. Smooth pursuit eye movements Smooth pursuit eye movements were evaluated as proportion of smooth pursuit (propSP) and gain of smooth pursuit (Gain). Gaymard, B., Pierrot-Deseilligny, C., Rivaud, S. & Velut, S. Smooth pursuit eye movement deficits after pontine nuclei lesions in humans. (D and F) Reproduced from Shichinohe et al. In addition, consistent with the significant difference in percent of pursuit neurons in the two areas (Figure 9A, action), caudal FEF inactivation significantly decreased pursuit eye velocity during pursuit maintenance, resulting in saccadic tracking, whereas SEF inactivation did not impair pursuit maintenance. J. Neurophysiol. conceived the project and designed the experiments. Ito, M. (2011). Smooth pursuit tracking is susceptible to an age-effect and may require that the examiner acclimate the patient to the task prior to recording. Ito, M. (2006). The relationship between saccadic and smooth tracking eye movements. Brain Res. (2003). Smooth pursuit eye movements can become jerky, with catch-up saccades leading to "cogwheel" pursuit, reminiscent of the ratchety limb movements in PD. (2004) and the adaptive modeling of Dicke and Thier (1999), providing evidence that MSTl is an area in which not only retinal error and eye velocity, but also head velocity are integrated to provide an estimate of target velocity in world-centered coordinates, consistent with the modeling of results from head-free pursuit experiments (Ackerley and Barnes, 2011). Ferrera and Lisberger (1995, 1997) showed that the initial open-loop response is a vector average of the responses that would be made to individual stimuli.

J. Vis. Pola, J., and Wyatt, H. J. Once the pursuit target has been selected and the eye moves across the remaining non-selected stimuli, the passive response induced should reduce pursuit velocity. Hence, when transient target motion probes are used during steady state pursuit the expected reactive response is still evoked (Schwartz and Lisberger, 1994). Paper presented at The Israel Society for Neuroscience 20th Annual Meeting, Eilat, Israel. Crucially, PD patients may not be capable of this modification of wT1 since their responses in the memory pursuit task do not show an abrupt increase in acceleration (Ito et al., 2012), even with a popout stimulus (Figure 13D). 22, 195206. (2012). The mechanism of prediction in human smooth pursuit eye movements. The gains in nondominant eye of lower left (533.33ms), lower right (633.33ms), and lower (233.33ms) were prolonging comparison to dominant eye (lower left, 266.67ms; lower right, 66.67ms; lower, 66.67ms) (Table 5). In the non-selected channel there is no priming of 2 or wT2 which remain inactive as indicated by crosses. Neurol. definition of SMOOTH-PURSUIT MOVEMENT (Psychology Dictionary) SMOOTH-PURSUIT MOVEMENT By N., Sam M.S. However, when target motion ceases unexpectedly, following a latency of ~100 ms, eye velocity generally decays to zero with a time constant of ~100 ms (Robinson et al., 1986; Pola and Wyatt, 1997) without evidence of overshoot. 24, 9811004. J. Neurosci. Oculomotor inhibition during smooth pursuit and its dependence on contrast sensitivity. 69, 460468. Activity reduction was observed even in the absence of catch-up saccades that frequently occur during pursuit. Cortex 1, 692701. Go/no-go cue was randomly presented. Normal controls exhibited initial smooth-pursuit component in the cued direction with a mean latency of 155 ms (Figure 11B1 *) followed by corrective saccades (Fukushima et al., 2011a,c; cf. 84, 23402355. Eur. Single target displacements. 22, 46754685. 151, 461501. ADS Importantly, this does not mean that the retinal component is eliminated; it still remains active in most circumstances and can correct for unexpected changes in the stimulus. In some cases, however, a deficit of smooth pursuit may be due to. Open arrowheads with dashed lines in (B) schematically indicate a proposed smooth-pursuit efference copy loop between the caudal FEF and the basal ganglia through the thalamus which is not shown in (A) (adapted from Cui et al., 2003). https://doi.org/10.1113/jphysiol.1961.sp006811 (1961). 27, 43344341. Exp. and JavaScript. 7:5. doi: 10.1167/7.1.5. Kim and Shadlen (1999) demonstrated that visual motion responses could be maintained during a delay period in prefrontal cortex neurons. 8). Pursuit eye movements of a disappearing moving target. If you put one finger in front of you and watch it as you slowly move it around,then you are making a smooth pursuit. All 150 dots moved along one of eight directions at 10/s for 0.5 s [2. cue 1, 100% correlation of Newsome and Pare (1988)]. Brain 119, 491505. 28, 11571165. Pos and vel indicate position and velocity. The congruent directionality of delay 1 and 2 discharge of visual memory + movement-preparation neurons was also observed when moving two spots stepwise during the action period so that the monkeys made saccades instead of smooth-pursuit (Shichinohe et al., 2009). Horizontal straight line on eye velocity trace in (A) indicates zero velocity. The prevalence of poor ocular motilities in a mainstream school compared to two learning-disabled schools in Johannesburg. The dorsolateral prefrontal cortex has been linked to temporal storage of sensory signals (i.e., working memory, Goldman-Rakic, 1995). Lisberger, S. G., and Ferrera, V. P. (1997). J. Neurophysiol. Worfolk, R., and Barnes, G. R. (1992). (B3 and C3) compare mean discharge rate during rightward (black)/leftward (blue) cue 1 visual motion for go and no-go trials, respectively. Brain Res. In all cases, though, expectation is the critical factor that allows initiation of such internally generated movements (Kowler, 1989; Barnes et al., 2002). The premotor pathways subserving saccades and smooth-pursuit eye movements are usually thought to be different. Shichinohe, N., Barnes, G., Akao, T., Kurkin, S., Fukushima, J., Kase, M., et al. (2009). The 25th and 75th percentile points of the maximum values in the centrifugal direction were explored (the green horizontal lines). Further evidence for selective difficulty of upward eye pursuit in young monkeys: effects of optokinetic stimulation, static roll tilt, and active head movements. J. Neurol. (A) Schematic illustration of the task. Ladda, J., Valkovic, P., Eggert, T., and Straube, A. 98, 14051414. For this, we used the paradigm devised by Newsome and Pare (1988, 0% correlation) that moved each dot randomly in different directions at cue 1. Newsome, W. T., and Pare, E. B. Smooth pursuit is another form of eye movement that enables tracking of objects moving in space. Cerebellocerebral projection from the fastigial nucleus onto the frontal eye field and anterior ectosylvian visual area in the cat. Ito, F., Ikeno, K., Kobayashi, N., Takei, H., Olley, P. M., Chiba, S., et al. Smooth pursuit eye movements respond to moving objects in an attempt to generate smooth eye movements that keep the eyes pointed at the moving object. Epub 2020 Sep 30. For example, the eyes may have trouble "keeping up" with the target (i.e. The target location was converted to the position vector, and then, the maximum and minimum peaks were detected for 3.0s (Fig. Neuroimage 39, 1931. 167, 404413. Meyer, C. H., Lasker, A. G., and Robinson, D. A. The extra-retinal component is not a trivial proportion of the total response; it can reach gains >0.6 prior to target appearance [see cyan trace in Figure 4D; data from Collins and Barnes (2006)]. Smooth pursuit eye movements maintain the line of sight on smoothly moving targets. The gains of both eyes were defined as the ratio of the slope of the regression line in both eyes to the slope of the regression line in the target between the 25th and 75th percentile points.
