Evidence
After bilateral injection of AAV5-CaMKIIa-ChR2-mCherry into dmPFC, strong mCherry-labelled axon terminals were seen in the basolateral amygdala, indicating a projection from dmPFC excitatory principal neurons to BLA.

Named in the paper
“dorsal medial prefrontal cortex (dmPFC)” and “basolateral amygdala (BLA)”
Made by
an AI model reading the paper (claude-opus-5, extract@0.3.0), 2026-10-10
Checked by

a second AI model (claude-opus-5) agrees, 2026-10-10

“The paper's AAV-ChR2-mCherry injection in dmPFC yielded robust terminal labeling in BLA in rats, matching direction, method, and described strength.”
