It is known that single neurons in visual area V4 are selective for visual features and that their responses are modulated by selective attention. Surprisingly, a new study by Mirabella et al. in this issue of Neuron found that V4 neurons also signal the behavioral response category of the attended feature.

Inferotemporal (IT) neurons in monkeys can respond to visual stimuli in a translation-and scale-invariant manner. In a neural circuit model based on a recently reported form of gain modulation by attention in area V4, the modulated visual responses of model V4 neurons produce object-centered receptive elds further down the visual processing stream, accounting for invariances exhibited by IT neu...

Abstract Background and Aims: Newcastle disease (ND) is a highly contagious disease that affects many species of birds and causes significant economic losses to the poultry industry worldwide and the pathogenicity of Newcastle disease virus (NDV) strains varies with different virulence. We aim to detect lentogenic (low virulence) ND virus (ND/IR 2010) using sentinel birds and molecular det...

Objective(s): Asthma results from the interaction between genetic and environmental factors. ADAM33 gene on chromosome 20p13 is associated with asthma and airway hyperresponsiveness. Materials and Methods: This is a case-control study, where four SNPs S1 (rs3918396), T1 (rs2280091), T2 (rs2280090), V4 (rs2787094) of ADAM33 gene have been assessed in patients with allergic asthma and normal con...

V4+-rich V2O5/carbon aerogel (V4+-V2O5/CA) composites were synthesized as electrode materials for supercapacitors via in-situ hydrolysis-condensation processing. Carbon (CA) promotes the deposition of amorphous vanadium oxide and catalyzes crystallization V2O5 nanosheets at much reduced temperature. With a uniform distribution in CA, special structure provides large specific area reactive sites...

The use of grey-scale contours, and fingerprints derived from this, has recently been used to analyse images for object recognition. The processing of these data can take a number of different forms. This paper describes a method for using characteristic aspects of the fingerprint, and geometrical relationships between them, to reduce an image to a set of simple geometric features. These featur...
