Distribution of Fast blue-positive neurons.

<p>(A) The sagittal brain atlas indicating the level of the section in B (purple line; i-viii). (B) Representative pictures of the brain sections in the cerebral cortex (i, ii and iii), thalamus and hypothalamus (iv), midbrain (v), pons (vi) and medulla oblongata (vii and viii). The neurons projecting to the contralesional spinal cord at C7-8 were labeled with Fast blue. Infarct is indicated with a red line and the observed area of Fast blue-positive cells are indicated with a purple line. The names of the brain areas are abbreviated as follows: Rostral forelimb area (RFA), caudal forelimb area (CFA), secondary sensory area (S2), hypothalamic area (Hyt), mesencephalic tegmental area (Mes. Teg.), red nucleus (RN), nucleus reticularis pontis (NRPN) mesencephalic trigeminal nuclei (Mes. Trig.), deep cerebellar nuclei (Cbll), nucleus reticularis gigantocellularis (NRGi), nucleus reticularis parvocellularis (NRPa), spinal trigeminal nuclei (Sp. Trig.), vestibular nuclei (Vest), dorsal medullary reticular nucleus (MdD), and ventral medullary reticular nucleus (MdV). Scale bar = 1 mm.
