It has been shown that fear conditioning improves the steady-state evoked potentials driven by a long lasting amplitude modulated tone in the inferior colliculus.

We inhibited the basolateral nucleus of the amygdala of rats by injecting a GABAa receptor agonist (muscimol) before the recall test session of an auditory fear conditioning paradigm and recorded t
