High Contrast Allows the Retina to Compute More Than Just Contrast

Moderate Contrast in the Evaluation of Paintings Is Liked More but Remembered Less than High Contrast

Many visual aspects of paintings, as well as exposure to art and cultural norms, contribute to the aesthetic evaluation of paintings. The current study looked at heightened visual contrast as an important factor in the appreciation of paintings. Participants evaluated abstract digitized paintings that were manipulated in contrast for an appreciation task and were later presented with these pain...

Neurotrophins: More to NGF than just survival

NGF's role in neuronal survival has tended to mask other potential functions. But now the generation of mice lacking both Bax - required for the death of NGF-deprived neurons - and NGF or its receptor has shown that NGF plays a key role in establishing cutaneous innervation and regulating neuropeptide expression.

A Spatial Calibrated AER Contrast Retina with Adjustable Contrast Threshold

Address Event Representation (AER) is an emergent technology for assembling modular multi-blocks bio-inspired sensory and processing systems. Visual sensors (retinae) are among the first AER modules to be reported since the introduction of the technology. Spatial contrast AER retinae are of special interest since they provide highly compressed data flow without reducing the relevant information...

High Stakes Require More Than Just Talk: What to Do About Corruption in Health Systems; Comment on “We Need to Talk About Corruption in Health Systems”

Reluctance to talk about corruption is an important barrier to action. Yet the stakes of not addressing corruption in the health sector are higher than ever. Corruption includes wrongdoing by individuals, but it is also a problem of weak institutions captured by political interests, and underfunded, unreliable administrative systems and healthcare delivery models.
