Fig. 1. Explanation of the recording procedure for the vectorial components of the
local electric organ discharges (LEOD). (A) An example of the three local
electric organ discharges recorded at a position of 50% of the body length.
For each orthogonal axis the single LEOD is shown. (B) Each LEOD was recorded
using a specialised probe (c.f. text) in the medial plane of the fish
(depicted by the black arrow). (C) The time difference of the LEOD in the
dorsoventral and rostrocaudal direction (indicated by the black bar in A)
results in a vector loop when both LEODs are plotted against each other (data
are given in V cm–1).
