To Remember, the Brain Must Actively Forget

Researchers find evidence that neural systems actively remove memories, suggesting that forgetting may be the default mode of the brain.

To Make Sense of the Present, Brains May Predict the Future

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.
