Neural dynamics and brain function

The summative properties of double flashes were examined during a period of rapid change of visual sensitivity, caused by a subsequent masking stimulus. The results indicate that the eye first weights each input flash according to the sensitivity of the eye at the moment of presentation (as revealed by a single-flash masking function) and then summates the weighted response exactly. A possible physiological process which could accomplish the retroactive weighting is discussed.
