Brightness function: Binocular versus monocular stimulation

Monocular versus binocular vision in postural control.

OBJECTIVE In previous studies about the control of posture there have been controversial findings. Our aim was to examine the role of monocular and binocular vision in controlling posture in quiet stance. METHODS Twenty-eight normal subjects were tested. We used a force platform in measuring postural stability. In main experiment, postural stability was measured in four conditions: both eyes ...

BOLD-Perfusion Coupling during Monocular and Binocular Stimulation

Previous studies have suggested that during selective activation of a subset of the zones comprising a columnar system in visual cortex, perfusion increases uniformly in all columns of the system, while increases in oxidative metabolism occur predominantly in the activated columns. This could lead to disproportionately large blood oxygenation level-dependent (BOLD) signal increases for a given ...

Cataract surgery: emotional reactions of patients with monocular versus binocular vision Cirurgia de catarata: aspectos emocionais de pacientes com visão monocular versus binocular

Purpose: To analyze emotional reactions related to cataract surgery in two groups of patients (monocular vision Group 1; binocular vision – Group 2). Methods: A transversal comparative study was performed using a structured questionnaire from a previous exploratory study before cataract surgery. Results: 206 patients were enrolled in the study, 96 individuals in Group 1 (69.3 ± 10.4 years) and ...

Monocular and Binocular Visual Tracking

Monocular symmetry in binocular vision.

Human vision is highly sensitive to bilateral symmetry in 2-D images. It is, however, not clear yet whether this visual sensitivity relates to symmetry of 3-D objects or whether it relates to symmetry of the 2-D image itself. We used a stereoscopically presented stimulus and a 3-D bisection task that enable us to dissociate object symmetry from image symmetry. The bisection stimulus consisted o...
