Experimental setup and principal observation of Reber et al. [1]. (A) Illustration of the task. Two target images were embedded in a sequence of stimuli shown with a stimulus onset asynchrony (SOA) of 150ms. After each trial, subjects indicated for each target whether they had seen it or not (bottom). (B) Summary of the principal observation: the response of concept cells to their preferred stimulus (straight lines) was reduced in amplitude and occurred later when a stimulus was not seen. This difference between seen and unseen images was most pronounced in the anterior MTL (i.e. the amygdala). The neurons did not modulate their firing rate in response to non-preferred stimuli (dashed lines).
