Groundbreaking ‘Map of Consciousness’ Aims to Revive Coma Patients

Scientists Unveil Pathways Linking Arousal and Awareness

Despite being a fundamental aspect of human existence, consciousness remains an enigma. However, in a groundbreaking study published in the journal Science Translational Medicine, researchers have created a ‘map of consciousness’ that could potentially help revive coma patients. This map illustrates the crucial pathways linking arousal and awareness – the two building blocks of human consciousness.

Mapping the Default Network

Using high-resolution MRI scans of post-mortem human brains, the team from Massachusetts General Hospital and Boston Children’s Hospital mapped previously unseen pathways between key brain areas. Together, these pathways form the ‘default network’ – the brain’s active resting state of consciousness.

The map revealed connections between the midbrain and pontine reticular formations (previously known to contribute to consciousness) and additional ‘extrareticular’ brainstem nuclei, which the researchers believe play a crucial role in human wakefulness.

Reviving Consciousness

Lead author Brian Edlow, an associate professor at Harvard University, explains, “Our goal was to map a brain network critical to consciousness, providing clinicians with tools to detect, predict, and promote recovery in patients with severe brain injuries.” The researchers believe stimulating specific sites within this network could ‘wake up’ connections vital for consciousness in coma patients.

Clinical Trials and Future Applications

The team is currently conducting clinical trials to test reactivating the default network and restoring consciousness in coma patients. They plan to use targeted stimulation techniques to reactivate the crucial pathways identified in the map.

Senior author Hannah Kinney notes the map could also aid understanding of a broad range of neurological disorders linked to altered consciousness, such as Alzheimer’s disease, vegetative state, and minimally conscious state.


This groundbreaking ‘consciousness map’ offers new insights into the neural pathways underlying arousal and awareness, two fundamental components of human consciousness. With potential applications in reviving coma patients and understanding consciousness-related disorders, this research marks a significant step forward in unveiling the mysteries of the human mind and paving the way for new therapeutic interventions.
