By digging out signals hidden within the brain’s electrical chatter, scientists are getting new insights into sleep, aging and more.
Neuroscience has found that gestures are not merely important as tools of expression but as guides of cognition and perception.
The brain can’t directly encode the passage of time, but recent work hints at a workaround for putting timestamps on memories of events.
Emerging evidence suggests that the brain encodes abstract knowledge in the same way that it represents positions in space, which hints at a more universal theory of cognition.
A controversial theory suggests that perception, motor control, memory and other brain functions all depend on comparisons between ongoing actual experiences and the brain’s modeled expectations.
Evidence mounts that organisms without nervous systems can in some sense learn and solve problems, but researchers disagree about whether this is “primitive cognition.”
Spiders appear to offload cognitive tasks to their webs, making them one of a number of species with a mind that isn’t fully confined within the head.
The cognitive scientist Donald Hoffman believes that evolution and quantum mechanics conspire to make objective reality an illusion.
