BLA (basal amygdaloid nucleus) projects to CEA (central amygdaloid nucleus)

Species: Rat
Result: present
Method: retrograde tracer
Sign: unknown
Evidence: Cholera Toxin B conjugated to a green fluorophore injected into the central amygdala retrogradely labelled neurons in the basolateral amygdala; labelled cell numbers were comparable across stimulation groups, and about 54% of odor-activated BLA cells were CeA-labelled after 25-Hz tonic LC stimulation versus about 11% in no-light controls.
