We previously detected mRNAs in a number of human T cell lines with a probe from within the Ig VH gene locus. We now show these mRNAs consist of Ig VH genes expressed in T cells. In one human T cell line, two RNA species have been studied and found to come from transcripts of unrearranged VH segments in which the leader exon, normally associated with VH transcripts in B cells, is replaced by a ...

The MELISA system is a distributed platform for multi-platform sports content broadcasting, providing end users with a wide range of real-time interactive services during the sport event, such as statistics, visual aids or enhancements, betting, and userand context-specific advertisements. In this paper, we present the revamped design of the complete system and the implementation of a middlewar...

The ability to accurately perceive the direction and speed of moving objects declines during normal aging. This is likely due to functional degradation of cortical neurons. Most neurons in the primate middle temporal area (MT) are direction-selective and their activity is closely linked to the perception of coherent motion. We investigated the mechanisms that underlie this age-related decline b...

Future mobile communications will bring a terminal diversity that until today has never happened. This paper describes a universal access system able to deliver multimedia content that is tailored for each type of terminal. The system is composed by three applications: a content analyzer application, a content customization engine and a multi-characteristics terminal simulator. The system uses ...

Segmentation of the visual scene into relevant object components is a fundamental process for successfully interacting with our surroundings. Many visual cues, including motion and binocular disparity, support segmentation, yet the mechanisms using these cues are unclear. We used a psychophysical motion discrimination task in which noise dots were displaced in depth to investigate the role of s...

Neurons in the middle temporal area (MT) are often viewed as motion detectors that prefer a single direction of motion in a single region of space. This assumption plays an important role in our understanding of visual processing, and models of motion processing in particular. We used extracellular recordings in area MT of awake, behaving monkeys (M. mulatta) to test this assumption with a nove...

T he U.S. agricultural production and food distribution industry is currently in the midst of major structural changes. To assist in understanding the implications of these changes and the future of the industry, faculty in the School of Agriculture at Purdue University in collaboration with industry representatives undertook a study to assess the future of the food production, processing, and ...

Mice that carry additional copies of genes comparable to those present on human chromosome 21 have been shown to perform better on memory tests when treated with drugs that target brain function. Could this be an important break-through in the search for pharmacological therapies to assist people with Down syndrome?

Cortical area MT/V5 in the human occipito-temporal cortex is activated by visual motion. In this study, we use functional imaging to demonstrate that a subregion of MT/V5 is more strongly activated by unidirectional motion with speed gradients than by other motion patterns. Our results suggest that like the monkey homolog middle temporal area (MT), human MT/V5 contains neurons selective for the...

This study aimed to identify neural mechanisms that underlie perceptual learning in a visual-discrimination task. We trained two monkeys (Macaca mulatta) to determine the direction of visual motion while we recorded from their middle temporal area (MT), which in trained monkeys represents motion information that is used to solve the task, and lateral intraparietal area (LIP), which represents t...
