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).

The dominant PCB components of our complex contaminant formulation are similar to those in the human milk formulation, Accordingly, this PCB formulation lacks effect early in neurodevelopment (prior to synaptogenesis) on N-methyl-D-aspartate receptors, specifically their density, which mediate the excitotoxic effect of domoic acid in the region of the brain where domoic acid seizures originate.
