The form of the human pupil
HJ Wyatt - Vision research, 1995 - Elsevier
The purpose of this study was to characterize the form of the pupil in normal human subjects.
Using a modified slitlamp, photographs of pupils were taken in steady illumination and 10–…

Directionally sensitive ganglion cells in the rabbit retina: specificity for stimulus direction, size, and speed
HJ Wyatt, NW Daw - Journal of Neurophysiology, 1975 - journals.physiology.org
The receptive fields of directionally sensitive ganglion cells in the rabbit retina were analyzed.
Several types of experiment showed that each point within the receptive field of the cell is …

Target position and velocity: the stimuli for smooth pursuit eye movements
J Pola, HJ Wyatt - Vision Research, 1980 - Elsevier
Smooth pursuit eye movements are usually thought to be guided only by target velocity. We
studied the effectiveness of target velocity and target position (offset from the fovea) as …

[HTML][HTML] Variability of visual field measurements is correlated with the gradient of visual sensitivity
HJ Wyatt, MW Dul, WH Swanson - Vision research, 2007 - Elsevier
Conventional static automated perimetry provides important clinical information, but its utility
is limited by considerable test–retest variability. Fixational eye movements during testing …

Offset dynamics of human smooth pursuit eye movements: effects of target presence and subject attention
J Pola, HJ Wyatt - Vision research, 1997 - Elsevier
Subjects made smooth pursuit eye movements with a target moving horizontally at 15 deg/sec.
At a specified location the target either: (1) suddenly vanished; or (2) jumped to the fovea …
