Adaptation effects on the FRA and the tuning curves.

<p>A. The frequency response area for average of 167 neurons in A1 area, which shows a decrease in their responses by adaptation. The responses of neurons in control sequence (up) and adapting sequence (down) that were calculated using LFP and MUA. B. The population tuning curves before (up) and after (down) adaptation. The relative frequency ‘0’ indicates the specific frequency that was used as adapter in the adaptation sequence.
