Startle Response System

The SR-LAB™ is the world’s most widely used system for testing startle habituation, pre-pulse inhibition, fear potentiated startle and cross-modal inhibition. The SR-LAB software allows users to utilize a virtually infinite combination of lights, tones, noise bursts, background noise, airpuffs, and foot shock. More startle response system info!

Place Preference

SDI’s Place Preference System provides place preference results as well as open field activity data. The place preference software reports the number of entries into a chamber, time in chamber, and exploratory pokes into a chamber, ambulations, fine movements, and has the ability to redraw the animals’ path. More place preference info!  

Human Behavioral Testing

The SR-HLAB™ uses electromyographic or photoelectric cell recording to measure startle response in humans. The SR-HLAB system plays a critical role in studying schizophrenia, drug dependency, and post-traumatic stress disorder. More human startle response info!

Avoidance System

The GEMINI™ avoidance system is designed for active avoidance (Trials to Criterion, Continuous) and passive avoidance (Classic, Trials to Criterion, Continuous, Learned Helplessness) testing in rats and mice. More avoidance system info!

Activity Systems

SDI’s Photobeam Activity Systems (PAS) are by far the most flexible and powerful systems for animal activity measurement. The PAS software provides real time reporting of activity such as distance traveled, speed, resting time, center/periphera counts, zone entries, and time in zones. PAS enclosures are available in the Home Cage and Open Field configurations.

Motor and Sensory

The ROTOR-ROD™ system uses “fear of falling” as a motivator to measure locomotor coordination in both rats and mice. The full size ROTOR-ROD model is designed for measuring rats, the bench-top model for mice, and a combination unit for rats and mice. More rotor-rod info!
