(A) Example compound receptive field from animal one during the prelearning phase of the yoked behavior. Each row plots the firing rate changes measured in response to the corresponding frequency tone pip. The vertical bar on the ordinate covers the frequency range of the target stimuli. The horizontal bar on the abscissa shows the time at which the tone pip was on. The compound receptive field shows the sum of spiking activity from all electrodes. The color bar codes firing rate changes above and below the average prestimulus rate.
(B) Compound receptive field from animal one during yoked postlearning.
(C) Excitability during pre- (Y1) to postlearning (Y2) in animal one (A1) and animal two (A2).
(D) Target onset selectivity changes. No significant changes were found.
(E) Response range. Animal two showed a significant increase (t test, p < 0.05).
Error bars indicate standard error of the mean.
