A mouse Nosepoke response with I/R Sensor and a tri-color stimulus light.
The Model 80116T Mouse Nose Poke unit places a tri-color stimulus light in the open hole of the 80116O basic mouse response device. Like that unit it is designed with reliable photo beam detection to signal when a subject enters the nose poke environment. The stimulus presentation feature requires three control lines and is best used with an interface and software control. There are two modes of operation. In the first mode it is possible to present a yellow, green or red stimulus of high or low intensity. In the second mode the yellow stimulus only can be presented in a ramp or flicker fashion at frequencies of 1Hz, 5Hz or 10Hz. The center of the photo beam detector is still placed 0.15" (3.81mm) back from the front of the nose poke block. The nose poke opening is 0.406" in diameter with a 0.5" countersink by 0.25" deep with a through hole that is 0.30" in diameter. (10.31mm x 6.35mm x 7.62mm).
