Evidence
After bilateral injection of AAV5-CaMKIIa-ChR2(E123A)-eYFP or AAV5-CaMKIIa-eArchT3.0-GFP into the basolateral amygdala, immunohistochemistry against the fluorescent tag revealed labelled cell bodies at the BLA injection site and labelled axons in the ventral hippocampus, where the optic fibers were placed just dorsal to the innervating fibers.
