Vogel Test: Anxiometer-102
The Anxiometer-102 accounts for misinterpretation of animal actions by accounting for those animals that maintain a hold on the sipper tube while drinking. Grasping the sipper tube would normally prevent the system from accurately assessing the number of licks. The Anxiometer-102 senses prolonged contact with the sipper tube and internally substitutes a seven cycle per second signal that mimics licking behavior. This technique was implemented based on the findings of Collier and Bells who determined the lick behavior of rats.
The Anxiometer-102 may also be employed as a standard drinking monitor. In addition to the front panel indications of performance, the instrument contains connections that allow the collection of data by any of Columbus Instruments general purpose Computer Counter Interface products. These connections facilitate automated data collection. A compete Anxiometer-102 system requires an Anxiometer-102 and a cage with sipper tube and suitably placed conductive grid. Such mechanical designs may be implemented from available materials or purchased from Columbus Instruments.
