Saccadic suppression
always to give rigorous quantitative expression to qualitative concepts. This was encapsulated in his famous review in 1948 of the properties of haem proteins. A notable paper by Wyman and D.W. Allen in 1951 could be said to prefigure what later became known as the allosteric hypothesis. After his return to (more or less) full-time science Wyman developed the theoretical basis of the scheme of ...
متن کاملMetacontrast and Saccadic Suppression
A vertical slit of light illuminated during horizontal saccadic eye movements appeared as a horizontally extended smear when stimulation was terminated before the saccade ended. However, on trials for which duration of illumination of the slit was extended into the period after the saccade, the smear appeared shorter and dimmer, and a clear image of the slit was seen. With further increases in ...
متن کاملSaccadic suppression of displacement: effects of illumination and background manipulation.
In contrast to other functions which are suppressed during saccades, saccadic suppression of displacement (SSD--a decrease in sensitivity to visual displacements during saccades) has often been considered to be due to efferent processes rather than to visual masking. The aim of this study was to explicitly assess the importance of visual conditions in SSD. In two experiments, a small computer-g...
متن کاملSaccadic suppression of image displacement.
HeImholtz (1867) suggested that the retinal image displacement vector, the afferent signal, is compared with the expected saccadic displacement vector, the efferent copy (Holst and Mittelstaedt, 1950) carried by the corollary discharge (Sperry, 1950) and this process may be called the " vectorial Helmholtzian com-parator for the frame of reference ". The results presented in this report show th...
متن کاملNeural mechanisms of saccadic suppression.
In normal vision our gaze leaps from detail to detail, resulting in rapid image motion across the retina. Yet we are unaware of such motion, a phenomenon known as saccadic suppression. We recorded neural activity in the middle temporal and middle superior temporal cortical areas during saccades and identical image motion under passive viewing conditions. Some neurons were selectively silenced d...
