MAZESOFT-8 is a complete and easy-to-use software for monitoring radial maze experiments. It has been specially designed to work with the BIOSEB radial maze apparatus equipped with rows of infrared photocells for the automated detection of animal position.

The software allows for the full control of the arm doors either manually (by means of a button panel in the computer screen) or automatically, when a trained subject is being tested.

MAZESOFT-8 allows the user setting any of the standard protocols for the study of working and reference memory in laboratory animals (rats or mice). The protocols are easy to configure, the user only have to enter some important parameters: designation of the baited arms, conditions to stop the experiments, time-interval between each trial, doors monitoring mode, criterion for considering the arm visited… Each protocol configuration can be saved and opened for use when necessary. A “trial header” can be use for recording all the necessary information associated with the current experiment (code of trial, experimenter, challenge, dose, subject identification, comments).

In MAZESOFT-8, the maze is virtually divided into 17 sections: 8 equally sized arms (each one divided into proximal and distal section) and a central area. One experiment can be composed of several trials, depending on the number of experimental groups and animals per group used in the study. The system considers an arm being visited when the subject has been detected in the distal part of the arm. During each trial, the elapsed time, permanence time in each area and current position of the animal can be visualized in real-time. Real-time information about the animal position and the number of visits made are also graphically shown on the screen. A Runtime data panel shows the cumulated number of working and reference memory errors together with other important data (response latency, number and list of visits and entries into the arms etc…)

MAZESOFT-8 provides a summary data table containing the complete information about each session (subject name, group, date) together with all the integrated data of interest. The tables of session can be re-organised before exportation according to parameters previously entered in the trial header (by subjects, by groups, by experimenter, etc.). Data from the summary data base as well as the detailed chronological listing of the animal positions for each session can be easily exported to Excel.

icone-param.gifParameters Measured

• Duration of the experiment
• Current position of the animal (rat or mouse)
• Number of working memory errors (first “visit” in the baited arms)
• Number of reference memory (number of “visits” in the unbaited arms)
• Number of working/reference memory (number of repeated “visits” into the baited arms)
• Total number of visited arms
• Response latency (total duration of the experiment / total number of visited arms)
• Number of different arms visited during the experiment (between 0 and 8)
• Number of arms visited until an 'error' (last arm visited included)
• List table showing the chronological order of the visited arms
• List table showing the chronological order of the entries into the arms
• List table showing the chronological order of the entries into the different zones of the radial maze
