Paying attention to neglected diseases.

Paying attention to neglected diseases.

Background: Recently, it has been shown that increasing body mass index (BMI) in asthma is associated with reduced exhaled NO. Our objective in this study was to determine if the BMIrelated changes in exhaled NO differ across asthmatics and controls, and to determine if these changes are related to increased airway oxidative stress and systemic levels of leptin and adiponectin. Methods: Observa...

Paying Attention to Memory

Paying attention to meaning.

Several paradigms show that responses to one event compromise responses to a second event for around 500 ms. Such effects are generally attributed to attentional capacity limitations associated with processing information in the first event. In a task in which targets could be distinguished only by their meaning, we varied the semantic relationship between distractors and targets following at d...

Paying Attention to Symmetry

Humans are very sensitive to symmetry in visual patterns. Symmetry is detected and recognized very rapidly, and eye fixations are concentrated along the axis of symmetry or the symmetrical center of the patterns. This suggests that symmetry is a highly salient feature. Existing computational models of saliency, however, have mainly focused on contrast as a measure of saliency. These models do n...

Paying attention to consciousness.

An engineering control approach is developed for the movement of attention, based on several features: experimental data indicating separate sites for attention modulation and for the creation of that modulation; the resulting analogy with motor control, to which an engineering approach has been applied; simulation and qualitative results supporting the presence of several of the necessary modu...
