Fu et al. 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
