摘要
Peak delay and amplitude variations of three regularly appearing components of photically evoked cortical potentials were investigated in waking cats during conditions of experimentally modified pupillary diameter. It was observed that the parameters of an early component were most sensitive to modifications in pupillary diameter. When compared with mydriatic and mobile pupil values, the values for both the latency to the initial deflection and peak delay of the first appearing component were reliably longer during miosis. The amplitude of this component was also smaller during the miotic condition than during conditions of mydriatic and mobile pupils. Component values obtained during mobile and mydriatic conditions did not differ reliably. © 1969.
