Listing's law: Difference between revisions

Listing's law was named after German [[mathematician]] [[Johann Benedict Listing]] (1808–1882). (It is not clear how Listing derived this idea.) Listing's law was first confirmed experimentally by the 19th century polymath [[Hermann von Helmholtz]], who compared visual [[afterimage]]s at various eye positions to predictions derived from Listing's law and found that they matched. Listing's law was first measured directly, with the [[Scleral lens#Use for eye movement measurement|use of 3-D eye coils]] in the 1980s by Ferman, Collewijn and colleagues. In the late 1980s Tweed and Vilis were the first to directly measure and visualize Listing's plane, and also contributed to the understanding of the laws of rotational kinematics that underlie Listing's law. Since then many investigators have used similar technology to test various aspects of Listing's law. Demer and Miller have championed the role of eye muscles, whereas Crawford and colleagues worked out several of the neural mechanisms described above over the past two decades.▼
