Retrograde tract tracing and immunofluorescence:

Retrograde tract tracing was performed using a 0.21% solution of cholera toxin B subunit (CTB; List Biological Labs), injected using standard stereotaxic coordinates (Paxinos and Franklin, 2001). Large areal injections of CTB were performed by pressure injection using a 33 gauge stainless steel needle and an automated syringe driver. For such injections 0.1l CTB was infused over 1 min, followed by a 5 min rest period before the needle was retracted. …

Antibody characterization:

Primary antibodies for immunofluorescence are described in Table 1.
