We designed a microcomputer (Apple IIe) hardware combination with software package called M4MA which offers a range of routines enabled us to set up, run and analyze data for research on rat’s feeding behavior over 48 hours. The three major outlines described are MOUSE-4-MAIN, MOUSE-4-ANALYSIS, and MOUSE-4-PRINTER. The routines are flexible and give the user efficient control over the parameters of the research and the collection and analysis of the data. Although designed for research on rat's feeding behavior, the software can be used for other research purposes, requireing only changes in the support hardware.
