The paper uses energy metabolism to infer directed communication patterns in the human cortex, showing sensory systems drive higher-order networks and default mode networks act as receivers.

This study uses combined PET/MR imaging to show that visual stimulation in humans increases glucose metabolism more than oxygen consumption in visual regions, while other cortical areas show oxidative downregulation.

The paper investigates the energetic costs of neuromodulator signaling in the human brain and finds that evolutionarily novel connections have higher energetic costs than sensory-motor pathways.
