The new approach establishes an opportunity to harness the success of immunotherapies that revolutionized the treatment of childhood leukemias for childhood brain cancers.

By revealing for the first time what happens in the brain when an animal makes a mistake, Johns Hopkins University researchers are shedding light on the holy grail of neuroscience: the mechanics of how we learn.

The team pinpointed the exact moment mice learned a new skill by observing the activity of individual neurons, confirming earlier work that suggested animals are fast learners that purposely test the boundaries of new knowledge.
