Evidence of a “memory code” for the acquired behavioral importance of sound. Level of tone importance was controlled by the amount of water deprivation; asymptotic performance was significantly correlated with level of deprivation (for details, see Rutkowski and Weinberger 2005). The area of representation of the frequency band containing the 6.0 kHz tone signal increases as a direct function of the level of behavioral importance of the tone, as operationally indexed by the level of correct performance.
