Conditioned odor potentiation of startle in rats

Behav Neurosci. 1999 Aug;113(4):787-94. doi: 10.1037//0735-7044.113.4.787.


An odor previously paired with shock was shown to be an effective stimulus for potentiating the startle response in rats (Experiments 1 and 2). This effect required more than 1 odor-shock pairing (Experiment 3), was relatively long lasting (Experiment 4), and was specific to the odor previously paired with shock (Experiment 5). The implications of these findings for the startle probe procedure and for neural models of learning and memory based on results obtained with that procedure are discussed.
