Figure 2.
Whisker and tactile sensory performance in male and female B6 mouse pups with (WT) or without (WC) whiskers. Data are expressed as mean ± S.E.M. * indicates significant differences between WT and WC and # indicates age differences compared to P4. (a) The body weight gains in male and female B6 pups with or without whiskers. In the cliff avoidance test, (b) the latencies for avoidance from a cliff edge, and (c) the number of head dipping observed during a session are presented. In the whisker stimulation test, (d) the number of twitching response and (e) head moving response toward a 30 times whisker stimulation were measured. In the tactile stimulation test, (f) the percentage of twitching responses to total 7 stimulation on their body were calculated.
