Vestibular Projections

Vestibular projections in the central nervous system consist of vestibular end organs which communicate with the brain stem and the cerebellum via the vestibular branch of the eighth cranial nerve. These nerves are also connected to the auditory fibers. Thus damage caused to these structures can cause both vestibular and auditory disturbances. The vital function of the vestibular system is to coordinate head and eye movements. The ability of the eye to stay focused on an object even while the head is moving is brought about by the vestibular system.

Abstract

The study uses the Posner paradigm to determine whether the condition of the cue can affect the reaction time of the subject. Most importantly is that the eye movement was prohibited. Using the data of 143 subjects, the ANOVA method and Bonferroni corrections, we have found out that the condition does influence the reaction time, however the difference between the cues is not significant Nonetheless the reaction time was far off from the target 100 ms due to inexperience and not understanding of the task set before the subjects. The results of the study have shown us two processes ...

Abstract

Eye movement tracking and analysis has gained popularity as a critical tool for evaluating interfaces and visual display. Existing tools and methods that are used in analyzing scan paths and eye movements are to a greater extent limited in the nature of tasks that they support. In particular, the tools used have been found ineffective in tracking large amounts of data that has high variations. Eye movement analysis has been used in psychology, medical research, advertising, and cognitive science. Today, using CCTV cameras, human eye gaze, and eye movement and blinking is relatively recorded with ease and with high ...
