title: Examination of three-dimensional movements in human embryos using computer imaging technology.
abstract: This paper describes the use of computer imaging technology to study in three dimensions the dynamics of differentiations in human embryos. Three-dimensional computer reconstruction technology was used to build a series of models of the brain/face and the ear region from fixed, serially sectioned embryos at representative stages. When certain principles are followed each model can be equated to one frame on a motion picture film. The dynamics of differentiation are then revealed as changes in size, shape and position (growth movements) of multiple structures as they build the definitive arrangement.
