A five-year “adversarial collaboration” of consciousness theorists led to a stagy showdown in front of an audience. It crowned no winners — but it can still claim progress.
Is It Real or Imagined? How Your Brain Tells the Difference.
New experiments show that the brain distinguishes between perceived and imagined mental images by checking whether they cross a “reality threshold.”
Memories Help Brains Recognize New Events Worth Remembering
Memories may affect how well the brain will learn about future events by shifting our perceptions of the world.
How a Human Smell Receptor Works Is Finally Revealed
After decades of frustration, researchers have determined how an airborne scent molecule links to a human smell receptor.
How the Brain Distinguishes Memories From Perceptions
The neural representations of a perceived image and the memory of it are almost the same. New work shows how and why they are different.
Machine Learning Highlights a Hidden Order in Scents
Efforts to build a better digital “nose” suggest that our perception of scents reflects both the structure of aromatic molecules and the metabolic processes that make them.
