Fig. 6. Dynamics of the storage and update of the neural representation of the
electric image. Amplitude of the novelty response is plotted as a function of
the number of local electric organ discharges (LEODs) in the baseline period.
Values are means ± S.D. of the novelty response amplitude
(I/I0) obtained in series of trials having baseline
periods of the same duration. The inset illustrates the experimental paradigm.
The duration of the baseline period of the increase-and-hold pattern was
varied to change the number of baseline LEODs before the amplitude step. The
number of baseline LEODs were counted (short baseline periods) or estimated by
multiplying the period duration by the fish EOD rate. Trial duration was 100 s
(two fish, filled symbols) or 30 s (three fish, open symbols). Each symbol
shape represents a different fish.
