Attending to Contrast [PDF]

Neuron, 2000
Studies of the neural mechanisms underlying attention build on the foundation of classical studies of the primate visual system that have focused on understanding how visual images are transduced, encoded, and analyzed by the brain. In most of these classical studies, anesthetized animals were presented with visual stimuli while physiologists recorded ...

Technical note: A simple and effective CO 2 delivery system for angiography using a blood bag

Indian Journal of Radiology and Imaging, 2009
Several angiographic techniques have been developed to image the arterial system, the commonest using iodinated contrast media. Useful as they may be, they are not without disadvantages. One other modality is angiography using CO 2 .

Perceived Blur in Naturally-Contoured Images Depends on Phase

Frontiers in Psychology, 2010
Perceived blur is an important measure of image quality and clinical visual function. The magnitude of image blur varies across space and time under natural viewing conditions owing to changes in pupil size and accommodation.
