Gray matter damage Gray matter damage results in loss of neurons, no matter what speed they were firing, in an area. Areas of very low amplitudes overall relative to surrounding and homologous areas relate to gray-matter damage, literally a killing of the neurons, so there are many fewer producing the electrical […]
