In primate primary visual cortex, neurons sharing similar response properties are clustered together forming functional domains that appear as a mosaic of patches or bands, often traversing the entire cortical depth from the pia to the white matter. Similarly, each cortical site connects laterally through an extensive network of intrinsic projections that are organized in multiple clusters (pat...

Recent imaging studies show that the human brain has structures specialized for the detection of eyes and the recognition of eye-related behavior. There is some evidence that such systems may be innate and play an important role in infant social development. The development of machine perception systems that detect eyes and analyze eye behavior will also enable new approaches to human-computer ...

Interrupting the processes which control ecosystem resources has dramatic impacts on the rangeland conditions. To protect ecosystems and landscape, it needs to understand the ecosystem processes which regulate the ecosystem resources. As main components of ecosystems, patches and inter-patches play important roles in energy and materials cascade. Ecologically, functional parameters such as stab...

Visual deprivation induced by monocular eyelid suture, a laboratory model for congenital cataract, results in shrinkage of ocular dominance columns serving the closed eye. We performed monocular suture in macaques at ages 1, 3, 5, 7, and 12 weeks to define the critical period for plasticity of ocular dominance columns. After a minimum survival of 8 months, complete montages of [3H]proline-label...

The locations of the eye pupil centers are used in a wide range of computer vision applications. Although there are successful commercial eye gaze tracking systems, their practical employment is limited due to required specialized hardware and extra restrictions on the users. On the other hand, the precision and robustness of the off the shelf camera based systems are not at desirable levels. W...

in this article, the linear array (with 20 elements in the horizontal orientation) of microstrip antenna is examined with horizontal polarization. the set includes three microstrip substrates. there is a power network in two lower substrates and microstrip patches in the upper substrate. excitation of patches has been done as coupled through the power network in two lower substrates. using the ...

Breast cancer is the most common aggressive in women while early detection of this can reduce aggressiveness. But it challenging to identify breast features such as micro-calcification from mammogram images by human eye because its size and appearance. Therefore, automatic essential for diagnosis proper treatment. This work introduces an automated approach segments any images. At first, preproc...

Many interactive single-user image display applications have prohibitively large bandwidth requirements. However, bandwidth can be greatly reduced by using gaze-contingent multi-resolution displays (GCMRDs) that put high-resolution only at the center of vision based on eye position. A study is described in which photographic GCMRD images were filtered as a function of contrast, spatial frequenc...

A neural network model for the self-organization of lateral connections and ocular dominance columns from uncorrelated binocular input is presented. The self-organizing process results in a network where (1) aaerent weights of each neuron organize into smooth hill-shaped receptive elds primarily on one of the retinas, (2) neurons with common eye preference form connected, intertwined patches, a...

Examination.-Pulse 120, temperature 103-00 F., respiration 22. She appeared toxic, but was rational and co-operative, although it was evident that she was quite blind. Herpetic ulceration of her lips and tongue were prominent features. There were tender patches of erythema on her elbow and foot. The visual acuity was perception of light in each eye with accurate projection. Both eyes presented ...
