What makes a person who they are is closely tied to the brain, but explaining self-awareness or locating a particular memory remains difficult. People may forget much of what they have experienced as they grow older, yet still feel a continuity of identity throughout life.
The article surveys six proposals aimed at keeping the mind alive, potentially beyond death. They include preserving brains in liquid nitrogen, improving the capabilities of living brains and storing memories in the cloud.
These ideas range from research questions to concepts that remain close to science fiction. The article considers how feasible they may be and notes that research into them could have benefits even if cognitive immortality proves impossible.
