introduction: counting is of the most basic mathematical abilities. many researches have demonstrated that different perceptual abilities can affect counting skills. we investigated the impact of visual search (vs) and visuoumotor organization (vmo) on counting speed. material  and  methods:   a  total  of  40  people  in  two  groups  of borderline  and  normal intellectual ability (20 subject...

Week-old zebrafish execute many complex, visually guided actions using a brain that displays the canonical vertebrate organization, but is less than a cubic millimeter in size. Recent studies have made considerable progress towards understanding the underlying neural circuit basis of these innate responses, at two fundamental levels. Large-scale population recordings have revealed how functiona...

In most animals, the visual system plays a central role in locomotor guidance. Here, we examined the functional organization of visuomotor reflexes in the fruit fly, Drosophila, using an electronic flight simulator. Flies exhibit powerful avoidance responses to visual expansion centered laterally. The amplitude of these expansion responses is three times larger than those generated by image rot...

The purpose of this study was to determine the reliability and validity of the Loewenstein Occupational Therapy Cognitive Assessment (LOTCA) battery. The battery provides an initial profile of the cognitive abilities of the brain-injured patient that can be used as a starting point for occupational therapy intervention and as a screening test for further assessment. The LOTCA consists of 20 sub...
