Resumen:
Pairs of naive Sprague-Dawley rats (male, adult) were randomly formed 1 month before testing. Dominance (D) was assessed by scoring priority to access to a limited water source, as well as displacement and agonistic encounters. Dominant rats were then subjected to 100 unsignaled footshocks (control dominant rats received the same number of shocks, but signaled). D was then reassessed. Results showed that unsignaled but not signaled shocks lead to a transient reversion of dominance.
