This topic is related to the work of Michael Levin’s lab, which I only recently found out about and have been digging into. They’ve released a bunch of papers, and Michael has given plenty of in-depth interviews available on YouTube. They’re looking at low-level structures like cells and asking “what can be learned/achieved by viewing these structures as being intelligent agents?” The problem of memory is tied intricately with intelligence, and examples of it at these low levels are found throughout their work.
The results of their experiments are surprising and intriguing: bringing cancer cells back into proper functioning, “anthrobots” self-assembling from throat tissue cells, malformed tadpoles becoming normal frogs, cells induced to make an eye by recruiting their neighbors…
An excerpt from the link below: Our main model system is morphogenesis: the ability of multicellular bodies to self-assemble, repair, and improvise novel solutions to anatomical goals. We ask questions about the mechanisms required to achieve robust, multiscale, adaptive order in vivo, and about the algorithms sufficient to reproduce this capacity in other substrates. One of our unique specialties is the study of developmental bioelectricity: ways in which all cells connect in somatic electrical networks that store, process, and act on information to control large-scale body structure. Our lab creates and employs tools to read and edit the bioelectric code that guides the proto-cognitive computations of the body, much as neuroscientists are learning to read and write the mental content of the brain.

- agumonkey 2y agoAs a sidenote, Peter Reddien's lab did other studies on planaria (videos are on youtube) and found cells that are supposedly dedicated to map the whole body and indicate how differentiation should go in that area (basically one input to the morphogenesis of this animal). It was, after levin's work, another eye openener, as you kinda approach biology as an information problem... everything happening has a piece of data that explains it, we just didn't look everywhere.
