Different types of whisker-based tactile discrimination tasks that have been established in head-restrained rodents. (A) Object localization. The animal needs to judge the position of a vertical pole. (B) Texture discrimination. The roughness of sandpaper presented to the whiskers has to be evaluated. (C) Bilateral frequency discrimination task. The animal has to compare the two stimulation frequencies on both sides. (D) Aperture discrimination. The width and centrality of the aperture have to be evaluated. (E) Schematic top view on the left hemisphere of mouse neocortex indicating several key areas for whisker-based discrimination behavior. S1: primary somatosensory cortex (barrel field), S2: secondary somatosensory cortex, M1: primary motor cortex, M2: secondary motor cortex, ALM: anterior lateral motor area, PPC: posterior parietal cortex; also indicated are A1: primary auditory cortex, V1: primary visual cortex, and TEa: temporal association area.
