AA << have uncovered how signals from a group of neurons in the brain's frontal lobe simultaneously give humans the flexibility to learn new tasks—and the focus to develop highly specific skills. >>
<< The study's key finding is that the brain uses the same group of neurons for performance feedback in many different situations—whether a person is attempting a new task for the first time or working to perfect a specific skill. >>
<< Part of the magic of the human brain is that it is so flexible, (..) We designed our study to decipher how the brain can generalize and specialize at the same time, both of which are critical for helping us pursue a goal. >> Ueli Rutishauser. ️

New Study Reveals How the Brain Says 'Oops!'. Cedars-Sinai Medical Center. May 5, 2022.
AA << recorded the activity of more than 1000 neurons in the medial frontal cortex of human epilepsy patients while they performed complex cognitive tasks. They found that domain-general and domain-specific performance monitoring neurons were intermixed within this brain region. The population activity gave rise to a geometry that allowed domain-general signals to be read out with more than 90% accuracy on single trials while at the same time retaining the ability to separate different conflict conditions. These results show how the human medial frontal cortex resolves the fundamental trade-off between task generalization and specialization, which is critical for cognitive flexibility. >>
