Rabbits were conditioned to avoid shock signaled by a tone. A second tone was randomly interspersed but did not signal shock. Neuronal activity 5 to 40 milliseconds after tone onset was greater to the shock-signaling tone than to the other tone. This difference reversed when the signal value of the tones was reversed.
