Human midcingulate cortex encodes distributed representations of task progress [Neuroscience]

Midcingulate cortex (MCC) contributes to cognitive control and decision making but its specific role in this process is highly mysterious. Here we use functional magnetic resonance imaging to test the predictions of a neural network model of MCC function. Confirming the model predictions, we find that human MCC encodes distributed, dynamically evolving representations of goal-directed action sequences. These results suggest that standard approaches for analyzing MCC function overlook the major portion of information encoded by this brain area. Rather, they indicate that MCC encodes the distances between representations of task events in task space, revealing how the MCC sustains the execution of extended behaviors.
