ACA (Anterior cingulate area) projects to MEA (medial amygdaloid nucleus)

Species: Rat
Result: present
Method: retrograde tracer
Sign: unknown
Evidence: Fluoro-Gold injected into the right or left MeA retrogradely labelled neurons in the cingulate cortex of both hemispheres, mainly in deep layers. Labelling was graded from weak in young males to very strong in young females and old rats.
Source: The medial prefrontal cortex to the medial amygdala connections may affect the anxiety level in aged rats

“Cingulate labelling after MeA injections was bilateral and mostly in deep layers, ranging from weak in young males to very strong in young females and old rats.”
