PURPOSE Strabismus may be associated with an asymmetry of monocular horizontal optokinetic nystagmus (OKN). It is unclear whether OKN asymmetries are associated with deficiency in binocular and/or stereovision. In the current study, patients with different degrees of binocularity were investigated. METHODS OKN was examined in the dominant and nondominant eyes of four groups of patients: (1) n...

Conflict in the Stroop task is thought to come from various stages of processing, including semantics. Two-to-one response mappings, in which two response-set colors share a common response location, have been used to isolate stimulus-stimulus (semantic) from stimulus-response conflict in the Stroop task. However, the use of congruent trials as a baseline means that the measured effects could b...

Perceived depth was measured for three-types of stereograms with the colour/texture of half-occluded (monocular) regions either similar to or dissimilar to that of binocular regions or background. In a two-panel random dot stereogram the monocular region was filled with texture either similar or different to the far panel or left blank. In unpaired background stereograms the monocular region ei...

1. Understand that heat therapies and electrotherapies are usually administered in conjunction with other treatments (e.g., exercise, manual therapy). 2. Know that heat and cold are both useful in reducing pain and spasm of musculoskeletal and neurological pathologies (Lehmann and deLateur 1999; Cameron 2003). 3. Be aware of evidence that superficial heating of skin produces muscle relaxation d...

Proc (Bayl Univ Med Cent) 2012;25(4):357–358 A 54-year-old man with dyslipidemia had smoked 1 pack of cigarettes per day for many years and recently had been experiencing chest pain on exertion and at rest. He came to the hospital because of a more severe episode of chest pain, and an electrocardiogram was recorded (Figure). He was on no medication. Patients with ischemic symptoms at rest and S...

Fourteen normal adult volunteers with normal binocular single vision and normal stereoacuity submitted to monocular and binocular degradation of their stereoacuity by cycloplegia and fogging with spherical lenses. Stereoacuity (SA) was reduced as soon as visual acuity (VA), both monocular and binocular, was reduced. There was a marked similarity in the degree of SA reduction produced by monocul...

Previous work has demonstrated that monoc-ular vision affects the kinematics of skilled visually guided reaching movements in humans. In these experiments , prior to movement onset, subjects appeared to be underestimating the distance of objects (and as a consequence , their size) under monocular viewing relative to their reaches made under binocular control. The present series of experiments w...
