BDA labeled fibers in Li after injecting it to KF, Su5, and 5N. a. BDA injection site in KF, Su5, and 5N. b. Low magnification of a hindbrain section showing BDA labeled fibers and neurons in Li. c. High magnification of b showing BDA labeled neurons and fibers terminating in the limbs of Li on the ipsilateral side. d. A higher magnification of c showing a large number of BDA labeled fibers terminating in the limbs of Li (note a labeled neuron in the lateral limb of Li). e. Low magnification of a hindbrain section showing BDA labeled neurons and fibers terminating in the limbs of Li on the contralateral side. f. High magnification of e showing BDA labeled fibers terminating in the limbs of Li. The scale bar in a, b, e=400 μm, the scale bar in c=200 μm, d, f=100 μm
