For example, the development of pain-like behaviors following excitotoxic spinal injury in male rats of three different strains and ovariectomized female rats is related to the rostrocaudal spread of a specific pattern of neuronal loss in the dorsal horn [48].
The cause of ALS is unknown, but there is evidence that excitotoxic damage to the motor neurons may play an important role in the disease pathogenesis (Choi, 1992; Rothstein, 1995; Shaw, 1994).
