Computer-generated 3-D reconstruction of case BR03, following a tracer injection into PML C1-forelimb zone, as depicted on the posterior view drawing of the cerebellum. The labelling consists of two contiguous populations of labelled cells: a low density scatter of cells located mainly in the lower part of the rostromedial quadrant of the pons, and a much larger and denser population located farther caudally. The labelling has a predominantly ipsilateral distribution. Scale bars: 500 µm.
