Full Anatomical Recovery of the Dopaminergic System after a Complete Spinal Cord Injury in Lampreys

Figure 1

Confocal photomicrographs of transverse sections of the spinal cord showing details of the dopaminergic cells in control and lesioned animals. (a) Dopaminergic cells in a control unlesioned larva. ((b), (d)) Dopaminergic cells in a 2 wpl larva, rostral (b) and caudal (d) to the site of injury. ((c), (e)) Dopaminergic cells in a 24 wpl larva, rostral (c) and caudal (e) to the site of injury. CSFc cells (arrows), VM cells (arrowheads), star points to the central canal. In all photomicrographs dorsal is at the top. Scale bars = 25 μm.
