Mean (± SEM) SAC consumption on the day of asymptotic extinction or spontaneous recovery test. Rats in the CSO-EXT extinction group drank significantly less SAC during the SR test than on the day of extinction indicating a spontaneous recovery of the CTA [* = p < 0.05]. Animals in the EU-EXT group did not exhibit a SR. SAC drinking at the SR test was significantly less in the CSO-EXT rats than in the EU-EXT rats [+ = p < 0.05]. These data indicate that the CS-only extinction animals showed a SR of the CTA, but the EU-EXT group did not.
