  ABSTRACT  Background: The brain response to temporal frequencies (TF) has been already reported, but with no study reported for different TF with respect to various spatial frequencies (SF).  Materials and Methods: fMRI was performed by 1.5T GE-system in 14 volunteers during checkerboard, with TFs of 4, 6, 8 and 10Hz in low and high SFs of 0.5 and 8cpd.  Results: Average percentage BOLD signa...

this research wants to consider the formation process of outline and spotted shapes in prehistoric periods. the light and the various form of its reflection, which appears as a shadow, silhouette and lightfast, and the way of facing human with nature surrounding him, is the theoretical base of this paper. light is one of the important elements in nature which help human to know and comprehend i...

Inhalation of ambient particulate matter causes morbidity and mortality in humans. One hypothesized mechanism of toxicity is the particle-induced formation of reactive oxygen species (ROS) - including the highly damaging hydroxyl radical ((·)OH) - followed by inflammation and a variety of diseases. While past studies have found correlations between ROS formation and a variety of metals, there a...

purpose: to evaluate the effect of levodopa-carbidopa on improvement of visual acuity, color vision, and visual field in patients with nonarteritic anterior ischemic optic neuropathy (naion) with onset less than 6 wks. methods: in this double-blind randomized controlled trial, 13 patients were treated with levodopa-carbidopa and 12 patients were treated with placebo for 3 weeks. after 6 months,...

Objectives: The visual-motor skill is one of the major factors in the learning process. Visual-spatial and visual analysis skills are components of the visual motor skill. Any deficiency in Visual-Motor skills and their components often causes problem in writing and learning processes in children. The aim of this study was to investigate the effect of occupational therapy (O.T.) intervention on...
