In addition, many references have been computerized to improve the mitigation time of responders. Selective reduction of the N95 amplitude, with preservation of the P50 component, suggests RGC dysfunction. which this spells out the hazards encountered in the event of transportation related release and the immediate emergency response procedures. The source of the P50 is debated, but there is some evidence suggesting that it is generated by RGCs with additional contributions from more distal sites.
