The cortex is organized in vertical and horizontal circuits that determine the spatiotemporal properties of distributed cortical activity. Despite detailed knowledge of synaptic interactions among individual cells in the neocortex, little is known about the rules governing interactions among local populations. Here, we used self-sustained recurrent activity generated in cortex, also known as up...
Received: 7 April, 2009 Accepted: 17 June, 2009AbstractBackground & Aims: Antidepressants are very common therapeutic agents in medicine. Design and using new antidepressants have built a new scope for depression treatment. Bupropion is an atypical antidepressant but it is used as an anti-smoke agent widely due to its smoke cessation. Its effectiveness in producing smoking cessation seems inde...
Background and Objectives: A fairly large amount of oil is absorbed to the food during deep frying. The aim of this study was to reduce the oil absorption of eggplant slices during frying by using osmotic dehydration pretreatment. Materials and Methods: Using maltodextrin (0, 20, 40% w/v) and sodium chloride (salt, 0, 10, 20% w/v), the effect of osmotic dehydration on different properties of e...
منطقه ی مورد مطالعه بخش کوچکی از حاشیه جنوبی البرز مرکزی است. و در شمال، شمال خاور شهرستان آرادان و در فاصله بین دره شمال جلیل آباد تا دره عبداله آباد واقع شده است. در این منطقه رخنمون هایی از سازندهای سنوزوئیک شامل قرمز زیرین، قم، قرمز بالایی، کنگلومرای هزار دره و نهشته های کواترنری قابل مشاهده است. روند ساختارهای زمین شناسی منطقه، اعم از چین ها و گسلها، خاوری - باختری تا شمال خاوری - جنوب با...
An ionic current model of the retinal horizontal cell is constructed. The horizontal cell models are interconnected by gap junctions to form a horizontal cell layer. The light response properties of the L-type horizontal cell are analyzed using this model. We demonstrate the functional role of each ionic current and the role of the feedback loop between cones and horizontal cells. The present s...
We describe a stochastic birth-and-death model of evolution of horizontally transferred genes in microbial populations. The model is a generalization of the stochastic model described by Berg and Kurland and includes five parameters: the rate of mutational inactivation, selection coefficient, invasion rate (i.e., rate of arrival of a novel sequence from outside of the recipient population), wit...
