A modifiable efference copy associated with the motor command that elicits an electric organ discharge (EOD) is found in mormyrid electric fish. It is a negative image of the expected effect of the afferent input that follows the EOD. A change in the afferent input pattern causes, over time, a corresponding change in the efference copy. The negative image is retained for at least one half-hour when the motor command is artificially silenced.
在长颌鱼目电鱼中发现了一种与引发电器官放电（EOD）的运动指令相关的可修改的传出副本。它是EOD之后传入输入预期效果的负像。随着时间的推移，传入输入模式的变化会导致传出副本发生相应的变化。当运动指令被人为沉默时，负像至少会保留半小时。
