Fig. 2. Schematic drawings and photos (insets) of the set-up used to test whether the mole-rat can perceive and localize seismic waves only through the paws. (A) Top view: ST, supporting table anchoring the suspended maze; T, suspended T-maze; CT, central table; D, doors controlling access to the entrance maze tube; C, clamp arms suspending T maze 1 cm above the central table; S, vibratory stimulus (mechanical shaker or stimulus mole-rat) source producing seismic waves on the central table; MR, mole-rat. (B) Back view of the entrance tube: SL, slit (3.5 cm width) in maze tube, enabling the experimental animal to move in the tubes with only its feet in contact with the board surface; X, gap of 1 cm between the suspended maze tube and the board surface; other letters are as in A.
