WebJan 4, 2024 · Similarly, the fixational eye movements (microsaccades + drifts) of concussed patients tended to cover a more vertical area during fixation periods (vertical-to-horizontal ratio of 3.49 ± 0.94 vs 1.12 ± 0.04, p < 0.005). Conclusions Oculomotor testing, specifically microsaccades is a potential marker for concussion. WebTo further study the characteristics of small saccades and how they are affected by scene tilt, we looked at the effect of image tilt on small fixational saccades made while fixating …

WebSep 9, 2011 · Fixational eye movements resemble a random walk, i.e., highly erratic movements that appear similar to Brownian motion. However, a more detailed analysis of the statistical properties indicates that there is a separation of timescales in fixational eye movements. On a short timescale (up to 20 ms), fixational eye movements show a … WebApr 1, 1998 · The data show that fixational eye movements cause a large component of response variance in alert monkeys, and the high reliability of neurons in primary visual cortex of alert monkeys is consistent with expectations from conventional biophysical models, and it suggests that activity in a modest number of neurons may suffice to form a ... WebFinally, fixational eye movements have large effects on visual perception. What is fixation duration? Fixation duration is the average time for fixations. Fixation duration typically ranges from 150 to 300 msec. Fixation duration, similar to number of fixations and dwell time, represents the relative engagement with the object.
