Figure 4From: Acute paretic syndrome in juvenile White Leghorn chickens resembles late stages of acute inflammatory demyelinating polyneuropathies in humansCNS-PNS transition at the ventral nerve root as the border of inflammation. The ventral nerve root (VR) of an affected animal (B) presents with a severe mononuclear infiltration and thickening in comparison to a control chicken (A). The arrows point to the CNS - PNS boundary. Again, the inflammatory infiltration spares the adjacent central white (WM) and grey matters (GM) and does not pass the PNS-CNS transition.
