CEA (central amygdaloid nucleus) functionally connects to BLA (basal amygdaloid nucleus)

Species: Rat
Result: present
Method: optogenetic circuit mapping
Sign: unknown
Evidence: Fos in basolateral amygdala was reduced in CeA ChR2 rats (over 200% below normal baseline in the reward group), and eYFP controls avoiding the shock rod had about 240% higher basolateral amygdala Fos than CeA ChR2 rats, indicating CeA activation suppressed basolateral amygdala activity.
