LACK OF INHIBITION. The brain functions in a homeostatic balance with both excitatory and inhibitory neurotransmitters in balance. Individual nuclei have an "inhibitory surround" to prevent inadvertent firing. If an abnormal brain lesion blocks normal connections, the inhibition is blunted and excitation pre-dominates, sensitizing a spread of electrical action, which could trigger a seizure.
