The passage around this formula
The third family does not record from tissue at all. It builds models — from biophysically detailed single-neuron simulations to abstract population-level dynamical systems to large-scale network models constrained by connectomic data — and tests whether those models reproduce, and ideally predict, patterns actually observed with the other two families. Sejnowski, Koch, and Churchland’s foundational 1988 statement of the field framed this explicitly: the aim is to explain how the electrical and chemical signals available to real neurons can implement the representations and computations that behavior requires, using simulation and theory to bridge levels that no single experiment spans on…

Addition combines quantities; subtraction measures the signed difference between them. Parentheses show what is combined before the rest of the expression is evaluated.
