Enhancing PET image quality with deep learning

The axial field of view (AFOV) plays a pivotal role in determining image quality in positron emission tomography (PET). While total-body PET scanners like the uEXPLORER offer superior sensitivity, they come at a higher cost ...

New deep-learning approach gets to the bottom of colonoscopy

Researchers have developed a pair of modules that gives a boost to the use of artificial neural networks to identify potentially cancerous growths in colonoscopy imagery, traditionally plagued by image noise resulting from ...

A role for neural noise in animal behavior

Researchers from EPFL and UNIL have used flies to show how behaviors may be shaped by seemingly random brain activity. This study raises new questions about the role of neural noise in moment-to-moment decisions.

Speed-accuracy tradeoff turns up gain in the brain

Widespread changes in neural activity enable people to quickly make a decision by "turning up the gain in the brain," suggests a human study published in eNeuro. The findings help to resolve a central issue in our understanding ...
