Cross-Cultural Perspectives On Neuroscience

A 2025 invited perspective published in Nature by Dr. Judy Illes and her team at Neuroethics Canada—based out of the University of British Columbia—argues that neuroscience and brain health research can be strengthened by including more cross-cultural perspectives, particularly when research involves Indigenous patients or draws on Indigenous knowledge systems, such as traditional, complementary, and integrative medicine (TCIM).

The authors suggest that ethical research in these areas should follow the “6 R’s”: respect, relationships, relevance, reciprocity, responsibility, and representation. They argue these principles help researchers build trust, improve collaboration, and avoid repeating past harms.

The paper notes that Indigenous communities have historically been excluded from brain and mental health research, or included without receiving meaningful benefit. In some cases, serious ethical violations occurred. One example is the Havasupai Tribe case in the southeastern United States, where blood samples originally collected by a team at Arizona State University for diabetes research were later used without consent for unrelated studies on schizophrenia, migration, and inbreeding; this violation infringed on the tribe’s informed consent, using blood samples—considered by the tribe to be a critical component of one’s identity—for research questions the tribe had no interest in asking.

Another example comes from a genomics study involving Indigenous San and Khoekhoe peoples in Namibia, where researchers reportedly published unrelated and private information that participants had not consented to share. The authors argue these cases show why stronger ethical standards are necessary.

Beyond ethics, the perspective also argues that Indigenous knowledge systems offer valuable insight into how the brain works. The authors suggest modern neuroscience has often prioritized technology and brain imaging over broader questions of how people learn, remember, and understand the world.

One example they discuss is the Kulin Nations’ understanding of the mind and brain, where knowledge, learning, and comprehension are viewed as interconnected with spirit, environment, and community rather than isolated within a single organ. Their use of songlines—systems that transfer knowledge through song, spoken word, art, and movement—has helped preserve detailed information about medicinal plants, astronomy, geography, and family histories for thousands of years.

The authors argue this aligns with modern neuroscience findings on memory and spatial learning. The authors point to Nobel Prize-winning research by May-Britt Moser, Edvard Moser, and John O'Keefe, which showed how the brain uses grid cells and the hippocampus to create spatial maps that support strong memory formation. Similar memory techniques are also used by competitive memory champions today.

Overall, the authors argue that combining neuroscience with broader cultural perspectives can improve both research quality and patient care, especially in fields involving mental health, cognition, and integrative medicine.
