a, Schematic of retrograde tracing from dHPC by injecting rgAAV-CAG-tdT in CA1 & CA3. Detection of retrogradely labeled tdT neurons (in red) together with nuclei stained with DAPI (blue) from coronal sections at 10x; insets show zoom at 40x; CLA: claustrum, MS: Medial septum; LSr: Lateral Septum, AC: Anterior Cingulate, TH – Thalamus; HY/fx: Hypothalamus/fornix, BLA: Basolateral Amygdala, LEC: Lateral Entorhinal Cortex (Scale: 1000 μm) b, Schematic and histology for inhibition imaging. St-GtACR2 (stained with DAPI) in AC/LEC and hSyn-GCaMP6f in CA1. Dotted line denotes placement of GRIN lens. Scale:400 μm.
