Pre-operative determination of the dominant hemisphere for speech and speech associated sensory and motor regions has been of great interest for the neurological surgeons. This dilemma has been of at most importance, but difficult to achieve, requiring either invasive (Wada test) or non-invasive methods (Brain Mapping). In the present study we have employed functional Magnetic Resonance Imaging...

This paper describes a new algorithm for the extraction of the critical area for opens. The presented algorithm allows for the analysis of large IC’s and non-Manhattan geometry. Concept of the contact/via contacting regions is proposed and its relevance is discussed. Illustrative examples of the proposed algorithm are presented.

Recent work shows that global motion sensitivity, a property of extrastriate cortex, can be altered by early visual deprivation, while binocularity, a property of primary visual cortex, is still plastic. This contradicts the hypothesis that critical periods end later at higher levels of the system.

desertification is the consequence of series of processes in which climate change and human activities are more important factors than others. arid and semi-arid areas have occupied most parts of iran. sistan region is one of arid areas of iran where wind erosion is an important factor of land degradation and soil deterioration. for classification of desertification intensity, several methods h...
