An unprecedented experiment seven years in the making has shaken the field of neuroscience. Researchers set out to answer one of science’s most puzzling questions: Where does consciousness come from?

A RECENT GROUNDBREAKING EXPERIMENT in which anesthesia was administered to rats has convinced scientists that tiny structures in the rodents’ brains are responsible for the experience of consciousness ...

For decades, debates about consciousness have been driven by elegant theories and small, carefully controlled experiments. Now a large-scale analysis of existing research is forcing a harder question: ...

The original version of this story appeared in Quanta Magazine. Science routinely puts forward theories, then batters them with data till only one is left standing. In the fledgling science of ...

Consciousness is famously a “hard problem” of science: We don’t precisely know how the physical matter in our brains translates into thoughts, sensations, and feelings. But an emerging research tool ...

An experiment seven years in the making has uncovered new insights into the nature of consciousness and challenges two prominent, competing scientific theories: Integrated Information Theory (IIT) and ...

A group photo from the original meeting in March 2018 at the Allen Institute in Seattle, WA, that kicked off the set of adversarial collaborations. IIT suggests that consciousness emerges when ...
