Whisker deprivation. (A) Comparison between the whiskers of an untrimmed control animal (left), a whisker-trimmed animal at the end of the deprivation (middle) and the same animal after whisker-regrowth (right). (B) Attack histogram of control animals. (C) Attack histogram of deprived animals (after whisker regrowth). The fraction of attacks placed on the thorax (79% of 456 attacks) in control adults was significantly different from the fraction of thorax attacks (22% of 459 attacks) observed in deprived animals (Fisher's exact test, two-tailed, p < 0.0001).
