  • In fish 6 and fish 7, CoLos located caudal to the 11th segment were ablated. For all the other fish, ablations were performed against CoLos located caudal to the seventh segment.

  • a In the unilateral ablation experiments (fish 8–14), impaired escapes occurred only toward the side of the ablation. Therefore, in the ″Number of total escapes,″ only those escapes that occurred in that direction were counted.
