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.

The reshuffling of neurons during fruit fly metamorphosis suggests that larval memories don’t persist in adults.

Consciousness, our experience of being in the world, is one of the mind’s greatest mysteries, but as the neuroscientist Anil Seth explains to Steven Strogatz, research is making progress in understanding this elusive phenomenon.

New experiments show that the brain distinguishes between perceived and imagined mental images by checking whether they cross a “reality threshold.”

Researchers uncover striking parallels in the ways that humans and machine learning models acquire language skills.

In all bilaterally symmetrical animals, from humans down to simple worms, nerves cross from one side of the body to the opposite side of the brain. Geometry may explain why.

Feelings of loneliness prompt changes in the brain that further isolate people from social contact.

The neocortex of our brain is the seat of our intellect. New data suggests that mammals created it with new types of cells that they developed only after their evolutionary split from reptiles.

The critical brain hypothesis suggests that neural networks do their best work when connections are not too weak or too strong.
