Elevated Plus Maze
Video Tracking System

MED-VPMR-LR
Elevated Plus Maze Video Tracking System for Rat

MED-VPMM-LR
Elevated Plus Maze Video Tracking System for Mouse

System Highlights

• Monitor activity using digital video cameras.
• Connect up to two mazes to a single computer to simultaneously
  monitor mice or rats.
• Measure activity at a temporal resolution of 33.3 ms.
• Radial-arm and junction-area data are analyzed independently.
• Run using a desktop or laptop computer.
• Record video directly to computer for later review of subject behavior.
• Features near infrared (NIR) backlight runway.
  
• NIR backlight is invisible to animal, yet provides superior contrast for accurate positional tracking of animal’s location.

Experiment Information

The following information is tracked in the Video Maze software:

• Session Time – The amount of time the experiment
  actually ran.
• Arm Time – The total amount of time the animal spent
  in each arm.
• Hub Time – The total amount of time the animal spent
  in the hub.
• Arm Explorations – The number of times the animal
  partially entered an arm from the hub.
• Arm Entrances – The number of times the animal
  completely left the hub and entered the arm. There will be at least
  as many arm explorations as there are arm entrances, and possibly
  more arm explorations then entrances.
• Closed Head Dips – The number of times the animal looked over
  the edge of the maze for at least 180ms while
  a portion of the animals body was in the hub or the closed arms.
• Open Head Dips – The number of times the animal looked over the edge of the maze for at least 180ms while the animal was completely outside of the hub, on the open arms.
