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...

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 ...

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

Seeing more clearly through psychosis: Depth inversion illusions are normal in bipolar disorder but reduced in schizophrenia.

Schizophrenia patients with more positive symptoms are less susceptible to depth inversion illusions (DIIs) in which concave objects appear as convex. It remains unclear, however, the extent to which this perceptual advantage uniquely characterizes the schizophrenia phenotype. To address the foregoing, we compared 30 bipolar disorder patients to a previously published sample of healthy controls...
