What this contributes

Discusses astrocyte ensembles and an expanded view of memory engrams.

The boundary of the evidence

A framework, not an identity-preservation technology.

Engram research, brain decoding and connectomics investigate different parts of how brains encode and use information. Tissue preservation adds another line of inquiry. None of the sources indexed here demonstrates transfer of autobiographical memory into yeast or continuation of a person's consciousness.
