2.   Changes in activation by stimulus simplification suggest that object images are represented by combinations of spots.

Left panel: Some spots disappeared by the stimulus simplification, suggesting that each spot represents a 'part' or 'a local feature' of the object image. 
Right panel: Spots A, B, and D were activated by the original fire extinguisher, but the stimulus without handle and hose did not activated spots A and B, suggesting that spots A and B relate to the representation of the 'handle and hose,' but spot D relates to the 'cylinder'. Spot C is the one activated by the cylinder but not by the original which includes the cylinder. The extracellular recordings from the spots give explanations of this result (see next).  The dots in the right indicate the sites for single cellular recordings (see next).
