Figure 1. Design of the 5-port behavioral apparatus used to monitor odor investigation behaviors.

Figure 1.

(A) Top-down (left) and front view (right) of the 5-port odor investigation apparatus. This apparatus allows a mouse to freely explore and sample among 5 different odors in a single behavioral session which the timing of no-poking behavior to sample the odors is acquired by a microcontroller. See Materials and Methods for a complete description. (B) Renderings of the 3D printed odor exhaust manifold (top) and odor port (bottom). Location of the infrared (IR) photobeams is depicted on the odor port rendering. (C) Picture of the assembled 5-port apparatus which is wire connected to a project enclosure box (towards the left of the apparatus) which houses the Arduino microcontroller allowing for data acquisition onto a removable SD card or onto a computer connected by a USB cable.
