The critical maturation time of central otolith neurons in processing spatial orientations was examined in Sprague-Dawley rats. With the use of immuno-hybridization histochemical methods, we observed c-fos expression in vestibular nuclear neurons responding to transverse movement on the horizontal plane as early as P7 and those to antero-posterior stimulation as early as P9. In the inferior oli...

an important issue in implementation of a gis system is preparation of data to be entered in gis. to produce spatial data for gis using photogrammetric techniques, conventional method is to apply photogrammetric and gis systems individually (off-line procedure). this approach is costly, time consuming and somehow unreliable due to the fact that 3d photogrammetric model is not available at the t...

this paper takes a close look at the process of evolution of france’s spatial planning system. the rich background and solid approach of spatial planning in france, introduces this country as one of the pioneers of planning in various levels from local to urban and regional scales. the vision of this country during last decades especially in the field of spatial-physical development planning an...

background and objective: vep is a powerful method to study visual system via evaluating evoked potentials. technologic and instrumental restrictions may be the reason of having studies on optical modulation and induction such as color, spatial frequency and contrast. developments of computer software and hardware may lead to an increase in the flexibility of pattern designs. material and meth...

Introduction: Acceptance test is a necessary procedure after SPECT system installation. The goal of this test is to reveal system's present condition, to compare it with manufacturer's specifications and also as a base for later tests. Methods: This study investigated four SPECT systems in Tehran. All of the quality control tests are performed on the basis of NEMA and IAEA recommendations...
