1. Recent studies of visual processing in the cat have shown stimulus-related oscillations in the 30- to 70-Hz range. We sought to replicate these findings in the monkey. 2. We recorded multiunit activity (MUA) and local field potentials (LFP) in areas V1 and middle-temporal area (MT), and MUA from the inferotemporal cortex (IT) of monkeys (Macaca fuscata). Recordings in all areas were made und...

It is not known how visual cortical neurons react to several moving objects and how their firing to the motion of one object is affected by neurons firing to another moving object. Here we combine imaging of voltage sensitive dye (VSD) signals, reflecting the population membrane potential from ferret visual areas 17, 18, 19, and 21, with laminar recordings of multiunit activity, (MUA), when two...

this paper seeks to address the issue of alienation from the perspective of mulla sadra. although mulla sadra did not explicitly employed the term alienation, equivalent terms, such as self-forgetfulness, negligence and self-unconsciousness can be found in his works. the outcome of the study is that mulla sadra is pursuing excellence and perfection of human beings through transcendent philosoph...

Abstract Population growth affects the competition between land uses. Inevitably, increasing demand for natural resources causes severe damage to urban environment. In addition, potential of water can be a problem related supply clean and suitable community. The geological structure soil, disaster susceptibility, issues with at location are challenges in determining development residential area...

The Phage Mu transposase (MuA) is a 663 amino acid momomeric multidomain protein. A tetramer of MuA catalyzes the replicative transposition of Phage Mu. MuA pairs the ends of the Mu genome, cleaves the donor DNA and subsequently joins the Mu DNA to the target DNA in a concerted cleavage and joining reaction known as strand transfer. A series of truncations deleting 101, 136 and 173 amino acids ...

An original synthesis method based on X-ray irradiation produced gold nanoparticles (AuNPs) with two important properties for biomedical research: intense visible photoluminescence and very high accumulation in cancer cells. The nanoparticles, coated with MUA (11-mercaptoundecanoid acid), are very small (1.4 nm diameter); the above two properties are not present for even slightly larger sizes. ...

A portable and power-free microfluidic device was designed for rapid and sensitive detection of lead (Pb(2+)). 11-mercaptoundecanoic acid (MUA)-functionalized gold nanoparticles (MUA-AuNPs) aggregated in the presence of Pb(2+) for the chelation mechanism. When we performed this analysis on a polydimethylsiloxane (PDMS) microfluidic chip, the aggregations deposited onto the surface of chip and f...

Trees can improve air quality, but at the same time, pollution might put them at risk. Plane(Platanus orientalis L) and willow trees (Salix babylonicaL) are important trees in the green space of Tehran. Plane trees in Tehran have experienced early autumn in recent years due to severe air pollution. The present study, investigated some physiological traits of these trees under study to determine...
