Quantitative assessment of photic driving in renal failure.
Photically driven EEGs were recorded from patients with renal disease using photic stimulation at integer rates between 3 and 12 flashes/sec. Changes in the structure of the power spectrum of the potentials produced by this stimulus paradigm are described as a function of a patient's clinical state. The basic overall findings are that (1) harmonic activity is attenuated while activity below the fundamental driving frequency is increased as a patient's clinical condition deteriorates, and (2) that these effects are substantially reversed and controlled by means of dialysis and renal transplantation.
