We investigated whether three-dimensional (3D) information in a scene can affect symmetry detection. The stimuli were random dot patterns with 15% dot density. We measured the coherence threshold, or the proportion of dots that were the mirror reflection of the other dots in the other half of the image about a central vertical axis, at 75% accuracy with a 2AFC paradigm under various 3D configur...

the global computer simulation based on the magnetohydrodynamic (mhd) theory describes the evolution of physical conditions in the simulation domain based on measurements for each point in the solar wind. considering the size of magnetosphere and strong spatial variation of the energy transfer process, the amount of transferred energy cannot be directly measured on the surface of magnetosphere,...

Background & Aim: DBS (deep brain stimulation) is a new and successful technique in treatment of symptoms of Parkinsonism especially after drug resistance. Research in this field is mostly designed for evolution of this technique. The present study aimed at evaluating the relationship between the angle formed in midsagittal and STN (sub-thalamic nucleus) axis line and recording l...

The asymmetries of internal organs are consistently oriented along the left-right axis in all vertebrates, and perturbations of left-right orientation lead to significant congenital disease. We propose a model in which a "left-right coordinator" interacts with the Spemann organizer to coordinate the evolutionarily conserved three-dimensional asymmetries in the embryo. The Vg1 cell-signaling pat...

Introduction: The activity of Hypothalamus-Pituitary-Adrenal (HPA) axis is increased following inflammation due to its closed relation with immune system. This axis indicates an increased secretion of ACTH, and corticosterone during acute inflammation while little is known about its activity during chronic inflammation such as rheumatoid arthritis (RA). In this study we measured the products...
