Seeing Transparency More Clearly

Seeing more clearly: recent advances in understanding retinal circuitry.

Among 10 breakthroughs that Science announced at the end of 2002 was the discovery of a photosensing (melanopsin-containing) retinal ganglion cell (RGC) and its role in entraining the circadian clock. This breakthrough exemplifies the ultimate goal of neuroscience: to understand the nervous system from molecules to behavior. Light-sensing RGCs constitute one of a dozen discrete RGC populations ...

Seeing Clearly and Moving Forward

THIS SURVEY HIGHLIGHTS SOME important trends in AI research and development, focusing on perceiving and affecting the real world. We will primarily address robotics, but we certainly don’t intend to imply that this is the only important area of AI research and development in the 21st century. We see tremendous importance in the continuing work in such areas as data mining, learning, knowledge r...

Systemic Embolic Events (SEE) in Atrial Fibrillation: SEEing Embolic Risk More Clearly.

Seeing depth coherence and transparency.

Gratings with different disparities are sometimes seen as transparent surfaces, each with a distinct depth, when they are superimposed, and sometimes they are seen as a coherent plaid confined to a single depth plane--stereo analogs of transparent and coherent motion. Briefly presented sinusoidal gratings of similar spatial frequencies are seen to cohere in depth. The resulting plaid generally ...
