Inper LM Lickometer

Detect animal licking through contact sensing, with adjustable sensitivity and TTL event output for recording and instrument integration.

Discuss configuration Make each lick an event. Inper LM Lickometer Detect licking electronically and send TTL events into recording or stimulation experiments. Inper LM uses an electronic sensor based on a high-frequency AC contact circuit. A compatible conductive drinking setup turns lick contacts into recordable behavioral events. Tongue meets spout. Detection begins. 02 · Contact sensing The front display shows count and sensitivity controls for checking detection at the bench. The number in the product rendering is illustrative, not an experimental result or a stated measurement limit. See the count on the device. 03 · Compact device The spout and connection environment can affect contact sensing. Check wiring and ground, adjust sensitivity, then compare observed licking with event output. Adjust sensitivity for the setup. 04 · Sensitivity The compact unit can be combined with different drinking arrangements. Confirm the spout’s conductivity and mounting, the animal’s contact path and the sensor connection. Adapt a conductive spout to your experiment. 05 · Spout compatibility Connect the sensing lead to the drinking setup and the TTL output to a compatible instrument. Check grounding and cable routing in the actual environment so interference is not mistaken for behavior. Connect the detector and its output. 06 · Connections Use the TTL output as an event input to a recorder. Preserve its timing relative to other measurements for event-aligned comparison. Add lick events to the recording. 07 · Event recording With a compatible fiber photometry system, use lick TTL as a Marker input and inspect fluorescence before and after events in its analysis workflow. Interpret lick detection and neural measurements separately. Follow fluorescence around licking. 08 · Photometry integration Send TTL to a compatible optogenetic or electrical stimulator as a trigger. Configure stimulus waveform, duration and trigger rules on that instrument and verify the complete signal path before the experiment. Link licking to an external response. 09 · Stimulus triggering Compare lick-event timing with independently measured physiological signals. Event timing Compare event records across conditions using consistent detection settings. Condition comparison Connect event output to stimulation or task-control equipment. Behavior-triggered experiments Build questions around behavior events. Confirm the conductive spout, sensing connection and ground. Assemble sensing Compare observed licking with count and external TTL recording. Verify detection Document sensitivity, apparatus conditions and external input settings for repeat experiments. Document the setup Connect, verify, then record. Inper LM provides lick-contact detection and TTL event output. Volume measurement, reward delivery and analysis by other instruments require their own configurations; include these needs when planning the setup. Start with detection. Plan the integration. 12 · Configuration Sensing principle Electronic sensor based on a high-frequency AC contact circuit Sensitivity Adjustable Output TTL event signal Drinking setup Compatible conductive spout; confirm connection requirements Purpose Lick-event detection and integration with external instruments Parameter Description Specifications and functions depend on the model, software version and delivered configuration.
