The propositional calculus that is based on the boundary operator can be interpreted in a way that resembles the logic of activation states and competition constraints in certain neural network models.  One way to do this is by interpreting the blank or unmarked state as the resting state of a neural pool, the bound or marked state as its activated state, and by representing a mutually inhibitory pool of neurons <math>A, B, C\!</math> in the expression "<math>(A, B, C)\!</math>".  To illustrate this possibility, we transcribe a well-known example from the parallel distributed processing literature (McClelland amd Rumelhart, 1988) and work through two of the associated exercises as portrayed in Existential Graph format.

From this we discover that all college Sharks are 30-something and married.  Further, we have a complete listing of their names broken down by occupation, as no doubt all of them will be, eventually.
