Interaction Of Disparity And Accommodative Vergence, Michele Liu Kung

Theses

To fixate on a target that moves from far to near, changes in blur and disparity activate accommodation and disparity vergence. The goal of this study was to experimentally obtain eye movement data from four subjects, and analyze this data using through a new signal processing algorithm known as independent component analysis (ICA). Preliminary data suggest that three underlying neural subcomponents are present where the two components of disparity vergence initiate the movement and the accommodative portion is activated to facilitate the steady state portion of the response.

ICA was used as a blind source separation technique to analyze experimental …
