How does a gymnotoid electric fish with pulse-type electric organ discharges (EODs) detect specific novelties in electroreceptive feedback from its own EODs if it is contaminated by EODs of a neighbor? To answer this question, experiments were performed on intact as well as on curarized animals. Specimens were curarized and their silenced EODs replaced by artificial pulses, S, in order to dissociate electroreceptive afferences 1 from the activity of the electric organ pacemaker. The animal's ability to detect small, local distortions in its own EOD field as well as in a substituted S-field was tested while various patterns of pulses, S, mimicking EODs of a neighbor, were presented (Fig. 1). The following results were obtained: [ABSTRACT FROM AUTHOR] |
