Key Features:
- Microsecond precision
- Does not generate electrical noise, allowing simultaneous electrophysiology and brain imaging
- Uses silent valves to avoid noise interference
- Includes video capture software and analysis modules
- Fully integrated system controls stimulation, data acquisition, and analysis
- Can combine visual, auditory (optional), and reward stimuli in a customizable paradigm
Lickometer Module
- Precisely measures tongue movements and lick duration/frequency with microsecond precision
- Uses collimated infrared light to detect licking without generating microcurrents or electrical noise
- Compatible with high-density electrodes like Neuropixels or SiNAPS
- Infrared system does not affect vision, allowing complex visual stimuli
- Silent medical-grade valves precisely control water delivery down to ≤1uL
- Minimizes valve noise interference and conditioning confounds
Video Capture System
- Includes software to monitor licking behavior, trigger video capture, and adjust field of view
- High-speed 200+ fps capture up to 720p resolution synchronized within 50us of behavior
- Adjustable focus 30cm range, control software, external triggering, infrared sensitivity
- Compatible with two-photon microscopy and other imaging systems
Software Modules
- Customizable paradigm creation without coding by coordinating stimuli, video capture, lick detection
- Fully integrates control, stimulation, data acquisition, and analysis
- Can assess conditioning and learning by combining licking data with visual, auditory, and reward cues
Analysis Modules
- Quantifies lick timing (e.g. ILI, licks per bout, bout length, raster plots, histograms, heatmaps)
- Video analysis tracks tongue, paw, and facial movements during licking (requires Nvidia RTX 3000+ GPU)
