Nigrostriatal dopamine modulates the striatal-amygdala pathway in auditory fear conditioning

Retrograde CAV-GFP was infused into the lateral amygdala and labelled neurons in the auditory striatum, confirming the striatal-amygdala projection.

After AAV-eGFP was injected into the auditory striatum, GFP-labelled striatal axons appeared in the lateral amygdala, with little viral spread toward the amygdala itself.

SNc (Substantia nigra, compact part) MBA:374 projects to CP (Caudoputamen) MBA:672 · Mouse

CAV-based retrograde labelling from the auditory striatum labelled midbrain dopamine neurons, and most of them lay in the SNc.

VTA (Ventral tegmental area) MBA:749 projects to CP (Caudoputamen) MBA:672 · Mouse

In the same retrograde labelling from the auditory striatum, a small minority of the labelled midbrain dopamine neurons lay in the VTA.
