Neural Information Processing Systems

Developing amethod forhigh-quality reconstruction ofseenimages fromthecorresponding brain activity is an important milestone towards decoding the contents of dreams and mental imagery (Fig 1a). In this task, one attempts to solve for the mapping between fMRI recordings and their corresponding natural images, using many "labeled"{Image, fMRI} pairs (i.e., images and their corresponding fMRIresponses).


The oldest-known humpback whale recording was hiding in an archive

Popular Science

The audio, etched onto a plastic disc in 1949, predates the era when researchers could even recognize whale calls. Breakthroughs, discoveries, and DIY tips sent six days a week. In 1970, a single record would change history.
