Axonal trajectories of Lmx1‐ and Atoh1‐derived PB neurons. (a) Lmx1a Cre‐reporter labeling in the midbrain (tdTomato, pseudocolored coral‐red). (b) Atoh1 Cre‐reporter labeling in the midbrain (tdTomato, pseudocolored coral‐red). (c) Nickel‐DAB immunolabeling for synaptophysin‐mCherry (Syp‐mCherry) in the midbrain of a Calca‐Cre mouse after injection of AAV‐DIO‐Syp‐mCherry into the PB. (d) Nickel‐DAB immunolabeling for Syp‐mCherry in the midbrain of a Pdyn‐IRES‐Cre mouse after injection of AAV‐DIO‐Syp‐mCherry into the PB. Abbreviations: IPN, interpeduncular nucleus; RN, red nucleus. All scale bars are 1 mm
