A loss of nerve cells in the cortex after encephalitis was reported already in the classical work by Nissl, Spielmeyer, and Spatz. A loss of nerve cells will become only noticeable if it amounts to at least 50%. But as such clear pictures are rarely found, estimations were always considered as doubtful and incorrect. Not only the number of cells is… (More)
The counting of nerve cells give an answer to the question whether there is a significant loss of cells in the cortex in the course of viral encephalitis. For normal animals, average cell numbers of 275.42 were counted; for infected animals divided into two groups depending on the severity of illness, 144.95 and 192.87 cells, respectively (p = 0.0001).
