When mice learn to do a new task, their brain activities change over time as they advance from ‘novice’ to ‘expert.’ The wiring of cell circuits and the activities of neurons reflect the changes, new research shows[1]. Using a two-photon imaging microscope and a wealth of genetic tools, researchers found that neural networks become more… Read more

The findings could help explain why humans are inconsistent and sometimes irrational. “Experts have long struggled to explain why people are so erratic, making one decision one day and… Read more
