a, Behavioral paradigm for stimulus detection and discrimination. For stimulus detection, uniform whisker deflection sequences were applied to a single C1 whisker (Target, green) and a reward was given if the animal correctly responded to the target side. For stimulus discrimination, a distractor sequence (black) was simultaneously applied to the C1 whisker on the opposing side. b, Same paradigm as in a but using direct stimulation of the C1-barrels. c, Same paradigm as in a but distractor sequences were replaced by direct stimulation of the C1-barrels. d, Behavioral paradigm for deviant detection. Two 20-Hz sequences were concomitantly presented on both sides of the animal. The target sequence additionally contained a deviant stimulus, occurring 1.5 s after sequence onset. We used either sequences of whisker deflections (red) or light pulses (blue) and presented either 1, 4 or 10 deviants in one target sequence.
