The cue for disjunctive and conjugate eye movements.
The principles of control theory have been extensively applied to vision and have aided the understanding of the pupillary light reflex (Stark and Sherman, I957), accommodationtitative analyses were carried out, and mathematical models suggested which attempted to explain performance. Although some work has been done on convergence movements (Westheimer and Mitchell, I 956; Rashbass and Westhei...
متن کاملBlink-related eye movements.
Eye movements that accompany a blink have been measured in human subjects by the use of a visual-persistence method. With straight-ahead binocular viewing, each eye typically rotates nasalward and downward 1-2 deg during the closing phase of a blink. These eye movements are more rapid than the lid movements as recorded by high-speed photography. In fact, the eyes have already completed their in...
متن کاملEye movements of stutterers.
As a consequence of recent inquiries into the brainstem activity of stutterers, saccades and pursuit were evaluated in stutterers and their matched normals while silent and talking. No ocular motor instabilities or aberrations caused by speech were found. Saccadic latencies and gains for the stutterers were normal, but peak velocities were higher and durations were shorter. This finding is cons...
متن کاملFixation Eye Movements
In day to day events we perform complex eye movements for various different reasons, such as object recognition and during self motion. These complex motions can be observed by using eye coils [8] or eye trackers. These techniques have been used for many years in neuroscience in optic flow studies [1] and vestibular studies [9]. Eye tracking is also commonly used in nonhuman primate studies to ...
متن کاملEye Movements and Schizophrenia
Smooth pursuit eye movements (SPEM) has been reported to be abnormal in schizophrenic patients. 30 schizophrenic patients and 15 normal subjects were examined for the quality of their smooth pursuit performance. 73.33% of the schizophrenics and 40% of the normal subjects had 'impaired' pursuit performance. The significance of the findings has been discussed.
