Nose Poke

The standard nose poke key is quickly becoming a staple fixture in rodent operant conditioning chambers however, many researchers feel that standard nose poke devices lack fundamental elements that may be crucial to the conditioning process. By simply poking its nose into a recessed entry well, the animal does not receive any tactile feedback that might otherwise facilitate the shaping and learning process. With this limitation in mind Med Associates has developed the rodent nose poke response keys.

Similar in design to our line of pigeon response keys (ENV-123, e.g.), the rodent response keys feature an opaque plastic response key that can be backlit to provide enhanced visual cues.


 

ENV-114

ENV-114M
Nose Poke Response with Three Color Cue for Rat

This alternative response device is mounted on a 3/8 size rat modular panel and has a 1.0" (2.5 cm) access hole which is bisected by a sensitive infrared detector placed 0.25" (0.64 cm) in from the front edge. The control amplifier operates on 28 V DC and produces a ground output whenever the beam is broken. The back of the unit contains a stimulus display made up of three colored LEDs (red, green, yellow).

Dimensions:
Panel: 3.0" W x 4.875" H (7.6 cm x 12.4 cm)

ENV-114AM
Nose Poke Response for Rat

This alternative response device is mounted on a 3/8 size rat modular panel and has a 1.0" (2.5 cm) access hole which is bisected by a sensitive infrared detector placed 0.25" (0.64 cm) in from the front edge. The control amplifier operates on 28 V DC and produces a ground output whenever the beam is broken.

Dimensions:
Panel: 3.0" W x 4.875" H (7.6 cm x 12.4 cm)

 

ENV-114

ENV-114BM
Nose Poke Response for Rat

This alternative response device has a single yellow stimulus light at the back of the nose poke opening and is mounted on a 3/8 size modular panel. It has a 1.0" (2.5 cm) access hole which is bisected by a sensitive infrared detector placed 0.25" (0.64 cm) in from the front edge. The control amplifier operates on 28 V DC and produces a ground output whenever the beam is broken.

Dimensions:
Panel: 3.0" W x 4.875" H (7.6 cm x 12.4 cm)

 

ENV-313

ENV-313M
Illuminated Nose Poke Response for Classic Mouse Modular Test Chamber

ENV-313W
Illuminated Nose Poke Response for Wide Mouse Modular Test Chamber

This unit includes a yellow LED stimulus light at the back of the access port, and an I/R control, source and detector. This response device is mounted on a 1/2 size mouse modular panel. The access port measures 0.5" (1.3 cm) in diameter by only 0.4" (1.0 cm) deep. Entry of the animal’s nose 0.25" (0.64 cm) into this area defines the response. The control amplifier operates on 28 V DC and produces a ground output whenever the beam is broken.

Dimensions:
Panels: ENV-313W: 2.355" W x 3.5" H (6.0 cm x 8.9 cm)
ENV-313M: 1.5" W x 3.5" H (3.8 cm x 8.9 cm)

 

ENV-314

ENV-314M
Triple Cue Nose Poke Response for Classic Mouse Modular Test Chamber

ENV-314W
Triple Cue Nose Poke Response for Wide Mouse Modular Test Chamber

This mouse nose poke module features individually controlled red, yellow and green LED’s mounted flush to the back of the access port, and an I/R control to detect nose pokes. The access port opening is 0.5" (1.3 cm) in diameter by 0.4" (1.0 cm) deep. Entry of the animal’s nose 0.25" (0.6 cm) into the opening will register a count. The operating voltage of this device is 28 V DC. This device is mounted on a 1/2 size mouse modular panel.

Dimensions:
Panels: ENV-313W: 2.355" W x 3.5" H (6.0 cm x 8.9 cm)
ENV-313M: 1.5" W x 3.5" H (3.8 cm x 8.9 cm)
