Fourth, the hippocampal-entorhinal map-like representation of action-outcome relations interacts with individual action representations in SMA during the action comparison process.

Third, we show the existence of representations in the SMA that are primarily related to the motor implementation of actions and that exist in parallel to the map-like representation of action outcomes in the hippocampal-entorhinal system.

Second, we found that the hippocampal activity scales with the distance between different action combinations in this abstract map that integrates action-outcome associations.

We first show that participants developed an integrated representation of multiple action-outcome associations as an abstract map, the relational structure of which is reflected in a hexadirectional modulation of EC activity.

Our paper in @natcomms.nature.com, we show how cognitive maps in the hippocampal system could solve the general problem of representing and relating multiple alternative action plans.

In our VR tasks, participants learned arbitrary motor action-outcome associations and later compared action combinations while their brain activity was monitored with fMRI.

The outcomes of the discrete and arbitrary motor actions were modulated along the two task-relevant dimensions.
