The periaqueductal gray matter
Webb10 okt. 2014 · In particular, the periaqueductal gray was found to be OROV-positive in 5 animals. This may suggest that the periaqueductal gray could be an important OROV gateway from the cerebral ventricular system into the brain. Both the inferior and superior colliculi, as well as the pons, were positive for OROV in 3 of 12 animals. WebbPreviously, it has been shown that streptozotocin (STZ)-induced diabetes leads to alterations in the dorsal horn of the spinal cord and the mesencephalic periaqueductal grey matter (PAG) . Among others, altered c-Fos and FosB expressions in these centers have been reported [72,73,74,75,76].
