Mouse Behavior Port

The mouse behavior port combines a photo-gate with a steel tube for delivering liquid reward, in a 3D-printed housing.

It allows freely moving subjects to indicate decisions and collect rewards.

The behavior port uses a photogate created from an infrared emitter with a narrow (10 degree) beam angle and a spectrally matched phototransistor.

A white LED embedded in the port illuminates it, to be used as a decision cue or for feedback.

The behavior port interfaces with the Bpod state machine via the port interface board.
