Three hypothetical neuronal assemblies, the top represents the concept of a lion, the bottom left one that of tiger, and the bottom right one that of a cheetah. The neurons interconnected by lines within each assembly represent the concept of the respective animal. The two neurons marked in green in the top assembly overlap with the circuit representing the concept of a tiger and the two neurons marked in blue in the top assembly overlap with the circuit representative for the concept of a cheetah. Quian Quiroga [182] assumes that partly overlapping representations might be the basis for learning of associations and conscious memories. (After Figure 5 of Quian Quiroga [182].)
