Schematic representation of the main features of the present hypothesis on the combinatorial aspects that by assembling neural groups can lead to “imagery” and to “imagination.” Details of the schema are briefly described in the figure and discussed in the paper. It is also indicated the extracellular matrix (ECM) as filler of the extracellular space (ECS) that can have a role in modulating the assembling of neuronal groups and their intercellular interactions (Agnati et al., 2006).
