Stimulus-specific adaptation. A: stimulus “A” evokes robust responses (red) both before and immediately after 30 repetitions of stimulus “B” (blue). B: same as A but with stimuli “A” and “B” interchanged. Note a fast and complete adaptation of responses to stimulus “A” but not to stimulus “B” after only 1 presentation (resembling rapid adaptation in visual cortex: Müller et al. 1999), the distinct kinetics of adaptation to the 2 stimuli, and the absence of cross-adaptation.
