Stimulation of the basolateral (BL) nucleus of the amygdala of rats excites the central nucleus of the amygdala which results in a fear response. Stimulation of which brain area 20-60 milliseconds before the BL stimulation inhibits this response?

Stage 1. An animal was exposed to a tone that was followed by a shock to its feet until it learned to freeze when the tone was presented (classical conditioning). Stage 2. The tone is presented with no shock many times. The animal does not freeze when the tone is presented. Stage 3. After a week, when the tone is presented the animal freezes. All stages occur in the same cage. What processes are described in Stages 2 and 3 of the experiment?

In an experiment after extinction of conditioned fear, the CS was presented in the same context (environment) where the extinction took place or in an unfamiliar context. How did the context affect the firing rate of neurons in the amygdala after the extinction?
