Fig 6. Triceps responses evoked by mechanical stimulation of the snout with and without the skin.

Fig 6

(A) Responses (% EMG area, normalized) during a 10 min. interval in one specimen and during another 10 min. interval one half hour after snout skin removal, showing that the responses are nearly abolished. The orange and blue color boxes indicate the data from this specimen used in the histograms in B. (B) Histograms showing the average responses (% EMG area, normalized) ± SEM for the 5 preparations tested (n = 5).
