In a Reddit Cognitive Biology forum topic I found this that (neuroscientifically) seems to go beyond Hinton’s capsules and such. Although there is no way to know how much of this holds true I felt it needed to be presented:
In this last section, I provide a framework that may be used to construct the environment in which a 3D+1 electrochemical physiology-model may unfold, and where the geometrical details of that environment can be extracted from actual observations. While leaving a fuller mathematical treatment for the future, I will try to show how such a framework can be used to gain a fresh perspective of the synaptic function. The driving questions of this discussion are: ”what is a cell?”, and ”how does electricity act on cells?”.
