Talk:Microsaccade

From Wikipedia, the free encyclopedia

I was told by a biology professor that if Microsaccades were forcefully prevented (i.e. with a temporary paralysing toxin introduced into the human system) that blindness resulted, until the microscopic muscular movements were restored, then full vision was restored. Anyone care to help in tracking down some evidence, as I feel it's a nice titbit to include Bigpinkthing 17:28, 22 May 2006 (UTC)

He may have been talking about the fact that the eyes cannot 'see' stationary images. In effect, when the eye is perfectly immobile, it becomes impossible to see anything, unless it moves. It is theorised that noncorrective microsaccades act to allow the eye to see by keeping all images in effective motion. -- Ec5618 22:11, 22 May 2006 (UTC)

[edit] Conflicting claims on microsaccade amplitudes

The Wikipedia entry on "Saccade" claims that "... microsaccades are tiny movements, roughly 20 arcseconds in excursion ...". This is very different from 2-120 arcminutes claimed to be the amplitude in this entry. What are the correct values? JL1971 20:17, 20 August 2007 (UTC)
