Abstract: The invention features a non-invasive method for diagnosing bovine spongiform encephalopathy in a mammal, e.g., a cow. The method entails measuring changes in pupil area in response to a neurotransmitter agonist or antagonist applied to the eye.
Abstract: A method and system for generating a dynamic, real time synchronized display of individual visual fixation points of one or more viewers superimposed on a video taped visual presentation for subsequent evaluation to assess the effectiveness of such visual presentation in communicating information.

Abstract: A mean distribution of viewer looking time for a group of individuals each viewing a dynamic audio and visual video program measures the mean attention span corresponding to each distinct audio and video component of the overall program. The video program is recorded in measured sequential scenes, with each scene corresponding to a selected audio or visual signal and being comprised of distinct visual areas of interest. Eye point of gaze data is recorded for the duration of the program for each individual viewer in the group. A compiled eye point of gaze data file is compared with a scene by scene data file to produce a third data file showing a mean distribution of viewer looking time for each selected audio and visual signal.
