Figure 1. Intersectional Targeting of Defined Neural Circuits.

Figure 1.

(A) Targeting gene expression to neurons with one defined output by retrograde transport of AAV2-retro-hSyn1-Cre. (B) Targeting gene expression to neurons with one defined input by anterograde trans-synaptic transport of AAV1-hSyn1-Cre. (C) Targeting gene expression to neurons with one defined input and one defined output by anterograde trans-synaptic transport of AAV1-hSyn1-Cre and retrograde transport of Cre-dependent AAV2-retro. (D) Targeting gene expression to neurons with two defined inputs by anterograde trans-synaptic transport of both AAV1-hSyn1-Cre and AAV1-hSyn1-Flp.
