Circular corridor
Apparatus
The circular corridor for Rats is composed of:
- a 65 cm metal square
- 2 PVC removable cylinders forming a circular corridor
- a sliding drawer for sawdust
- infrared sensors to detect the locomotion of the animal
For Mice, we propose circular corridors in racks of 8 apparatus:

The circular corridors are connected to an electronic interface, which provides the formatting of signals from infrared sensors and allows communication with the computer.
- Software

The software can manage up to 48 circular corridors, each apparatus remaining independent. The software that manages the experiments allows:
- displaying in real time the locomotor activity
- storing data per configurable unit time (from1 sec to several hours)
- recording duration: from 1 minute to several days
- data: activity in each quadrant, distance traveled, …
A software module allows:
- displaying results of a lot of experiments on the same file
- calculating several output variables and their kinetics per customized time units
All the results are displayed in a Microsoft Excel compatible datasheet.
