Cryonics is the preservation of the brain by cooling to subzero temperatures.
The goal of cryonics is to preserve the memories in the brain. This includes the personality, emotions, and aspirations of the person, everything that makes them a unique individual. These memories might be recoverable in the distant future with high enough technology
In a lab setting, good preservation quality has been achieved. We have Electron Micrographs demonstrating that some information can be preserved. This has never been extended to real-world human patients. Cryonics brains are currently being preserved with protocols that are based on laboratory work, but remain largely unvalidated. One of our primary goals is to validate the human protocols.
It would probably be 100 years or more before we could reconstruct the memories in a preserved brain. Reconstruction would require very advanced Future Technology but no new physics. It's a complex engineering problem, but one that we are likely to eventually solve.
Quality preservation doesn't come easily. Most cases are severly compromised by obstructive laws, vast distances, poor planning, and tight budgets. Our mission is to cultivate cryonics clinicians to improve patient care, including building a branch facility in the Bay Area.
This scan demonstrates the complexity of neurons.
Memories are encoded in these structures.
There are 100,000,000,000 neurons,
each with about 2000 synapses (connections)
