Executive summary: A new paper reframes cryonics as structural brain preservation, focusing on maintaining the brain’s physical structure to potentially enable future revival technologies, with fluid preservation emerging as a promising and cost-effective method.
Key points:
Structural brain preservation aims to maintain brain structures encoding memories and personality, rather than focusing solely on low-temperature storage.
Various preservation methods are reviewed, including cryopreservation, aldehyde-stabilized cryopreservation, fluid preservation, and fixation with polymer embedding.
Fluid preservation in formalin shows promise for long-term structural preservation, based on studies of brain tissue preserved for up to 55 years.
Oregon Brain Preservation offers free fluid preservation as part of a research study in select areas.
All current brain preservation methods are considered experimental, and more research is needed to corroborate and improve these techniques.
The authors encourage discussion and involvement in the field to advance research and public understanding of structural brain preservation.
