Footshock stimulation and NE iontophoresis cause similar effects in BLA neurons. A, Firing rate histogram of a neuron showing inhibition in response to footshock. B, This same neuron shows inhibition in response to NE iontophoresis. C, All neurons that display inhibitory responses to footshock (p = 0.003) also display inhibitory responses to NE iontophoresis (p = 0.004). D, Example of a neuron showing excitation in response to footshock. E, This same neuron shows excitation in response to NE iontophoresis. F, The majority of neurons that display excitatory responses to footshock administration (p = 0.003) also display excitatory responses to NE iontophoresis (p = 0.002).
