false JAX_SLW_001 1.1 Sleep Wake Adult Week 15 To quantitate sleep behavior in mice using automatic detection of movement with a piezoelectric floor, and threshold/statistical analysis software. Sleep-Wake Monitoring Quad Cage and Sensor System (Signal Solutions, Lexington KY) is used to monitor mouse activity throughout a given time period. It records the amplitude of the electrical signal generated by force on the piezoelectric sensors, then uses software to set signal thresholds and statistically analyse and classify the activity as sleep or wake. Data are recorded as a confidence classification of sleep/wake over time, and include amplitude.
