NEUREC - a program package for 3D-reconstruction from serial sections using a microcomputer.

A software package is described to reconstruct three-dimensional pictures in true perspective from a series of parallel sections using a low-cost computer system (Apple II plus). Data sampling via a graphic tablet and graphical output on the monitor screen or a digital plotter are assigned to different programs under control of a menu program. The number of data representing the object under study is unlimited. Originally written in BASIC, the programs were translated to machine language. As an application of the package, reconstructions of an identified large interneuron of the locust brain are presented.
