It is too early to say whether the brain uses anything like Elia smith's mathematical technique to build structure into vectors and then translate them into neural activity. But his work suggests one possible mechanism whereby the brain might combine concepts into more complicated kinds of relational representations. Hence we have a start at seeing how concepts can function in the explanatory way suggested by the knowledge view: explanations are built out of complexes of relations that can be represented in brain patterns. Moreover, because concepts on this view have the same underlying nature as patterns of activation in neural populations, the knowledge view remains compatible with prototype, exemplar, and multimodal views of concepts. In those rare cases where strict definitions of concepts are available, as in a triangle is a figure with three sides, the necessary and sufficient conditions can be represented by relations between concepts that can be captured by vectors of vectors and then modeled as neural activity.
