Simultaneous whisker deflections resulted in trials with a response in only 1 whisker barrel. A: schematic of the dual whisker experimental paradigm. Trial-average image from dual whisker deflections resembled a linear sum of 2 responding whisker barrels. Single-trial responses exhibit variable response spatial profiles. Trials were sorted into 4 response categories: barrel 1 responds, barrel 2 responds, both barrels respond, and no response. B: example single-trial images (15–20 ms after stimulus presentation) from each of the 3 response categories. Scale bar (1 mm) applies to all images.
