A simple computerized system for plotting the locations of cells of specified sizes in a histological section

A computerized plotting system is described which generates an outline of a histological section on an oscilloscope screen, and displays within its boundaries the positions of labeled neurons whose coordinates are sent to the computer electronically. Measured cell diameters can also be entered, allowing the computer to generate displays of the distributions of cells within specified size ranges. All data are saved by the computer, and any portion of a distribution may be examined oscilloscopically at several levels of magnification; moreover, three-dimensional displays may be generated wit appropriate programs.
