Fig. 6. Success (%) in selecting the correct maze arm leading to the vibratory
source when the generated vibratory waves could only reach the mole-rat's feet
(Experiment) or did not reach any part of the mole-rat's body (Control).
Values are means ± S.E.M.
(N=7 subjects in each of two stimulus sources). Broken line
represents random choice (50%) of maze arm.
