Fig. 6. Bilateral pulse numbers and steering. (A) Patterns with different numbers
of sound pulses were presented from the left and right side. The numbers of
pulses presented from the first and second speaker varied from 6:0 to 3:3 to
0:6. Lateral deviation depended on the number of sound pulses presented from
each side. When the same number of pulses was presented from both sides, the
animals almost walked straight ahead. (B) Lateral deviation in dependence of
ratio of sound pulses presented from the left and right speaker. The lateral
deviation depended on the pulse numbers perceived at each side. (C) Overall
path length walked during the trials. Translation velocity increased with the
amount of steering.
