Shannon information only applies to the transmission of messages. Shannon acknowledged it does not address transmission of meaning, semantic information. So, somewhere along the line neuroscience has to explain how meaning is transmitted. A general theory of info would help in that regard.

More generally Information "represents" a value. Information is compressed representation, so to speak. Information is about copying (representation) and transmitting configuration states of the world. It having to do with "state configurations" sets it apart from physical laws.

But she mentions types of info - semantic, perspective, and syntactic. There is also the notion of Shannon vs semantic information. Semantics gets into encoding. Also, weirdly enough Howard Pattee's "epistemic cut" idea relates information to biology which gives a solid grounding for another perspective. This is all very heady stuff.

One thing is see is a confusion between computing and information processing. info processing happens at all levels of biology, "computers" only certain levels.
