Maze Test Packages

Med Associates manufactures a complete line of modular components for simplified and economical maze construction for both rats and mice. The modular hub walls and runway ends support most ENV-007, ENV-008, or ENV-307W series operant test chamber accessories. Mazes are easily automated with I/R photobeam packages, auto guillotine doors and MED-PC^® interface and software packages as illustrated in the sample packages. Product information on individual components follows the brief package descriptions.


These complete radial arm maze packages feature modular test environments specifically designed for the rat or mouse. All control modules and software are identical. Each maze features eight automatic guillotine doors, dual sensors at the entrance to each runway, and a pellet receptacle and head entry detector at the end of each runway with a 45 mg (rat) or 20 mg (mouse) pellet dispenser. The 14 mg pellet dispenser (ENV-203-14) is available by request in place of the 20 mg pellet dispenser (ENV-203-20). The standard maze software application (SOF-700RA-6) provides for a user defined adaptation time and session test time. The test session is also ended when the animal has fully explored all eight runways. The standard data collection includes the number of entries and time in zone for the hub and all eight runways as well as "end counts" in each runway. Additional data includes total runways correct, total runway errors, the sequence of runways entered, and the elapsed time in seconds to runway completion. This MedState Notation™ procedure may be edited by the user or used as a model to create unique applications. Custom code is also available (sold separately). Since two interface modules are needed for each radial eight arm maze, the MED-SYST-8 interface and software package will run up to four mazes and MED-SYST-16 will run up to eight mazes.


These complete T-Maze packages include test environment specifically designed for the rat or mouse. All control modules and software are identical. Each maze features three automatic guillotine doors, dual sensors at the entrance to the start runway, a single sensor at the entrance to each goal runway, and a pellet dispenser with head entry detector at the end of each goal runway. The 14 mg pellet dispenser (ENV-203-14) is available by request in place of the 20 mg pellet dispenser (ENV-203-20). These basic mazes can be enhanced to meet a wide variety of applications. The standard maze software application (SOF-700RA-9) provides a left/right/alternate training procedure plus a forced/delay/choice task with applicable user defined variables. Each task requires operator intervention to return the animal to the start box; however, all timing and performance data is recorded automatically. These MedState NotationT™ procedures may be edited by the user or used as a model to create unique applications. Custom code is also available (sold separately). Order a MED-SYST-8 or MED-SYST-16 interface and software package separately to run up to eight or sixteen test stations respectively.


These complete Elevated Plus Maze packages include test environment specifically designed for the rat or mouse. All control modules and software are identical. Each maze features a sturdy base with plastic runways. Dual I/R photobeams at the entrance to each runway monitor the activity of the animal. Interface and software packages sold separately. The standard plus maze software (SOF-700RA-3) provides the number of experiments and entrances into the open and closed runways and the time spent in the open and closed runways. Since two mazes can share some interface components, contact Sales for cost savings options if multiple mazes are ordered.
