This unit includes an 8 oz (236.6 mL) bottle and Lixit® valve to eliminate leakage at the sipper tube. It may be used with direct sipper tube aversive stimulation or scrambled foot aversive stimulation. Oversized reservoirs may be used with this unit for long term studies without any change in performance. Force lickometry offers a completely different way to monitor licking behavior that defines responses better than contact or photobeam lickometers by adding a second dependent variable, force or motivation, two threshold levels are user-defined and the force lickometer signal is processed for counts and time above each threshold as well as the sum of the points above threshold (area under the curve/force). The range of force is 0 to 50 grams. The data for each bout is stored in an ASCII file. This system consists of a precision force transducer and transducer amplifier that combined with an infrared head entry detector, further defines the lick response. An adjustable threshold control determines when a lick count response signal is issued. The head entry detector and lick response output may be connected to any 28 V DC input. Due to the full size panel this unit can only be used in the extra tall ENV-007 series of modular test chambers.
The force lickometer also requires a DIG-744 interface card, SG-506 power supply, assorted cables and SOF-809 software application. Contact sales for additional information.
