Purkinje information


Purkinje is a name attributed to several biological features, so named for their discovery by Czech anatomist Jan Evangelista Purkyně:

  • Purkinje cells, located in the cerebellum
  • Purkinje fibers, located in the heart
  • The visual Purkinje effect of how human beings do not see color in dim light
  • Purkinje images, reflections of objects from the surface of the cornea, and from the anterior and posterior surfaces of the lens
  • Purkinje Incorporated, a company that develops healthcare information technology software and services
