SR-HLAB™ Human Startle System
(Formerly EMG-SR)

SR-HLAB Human Startle System – for clinical research from the designers of the world’s most widely used startle system.

The SR-HLAB startle response system plays a key role in the investigation of the pharmacology and physiology of schizophrenia, drug dependency, post traumatic stress and other disorders. The SR-HLAB allows you to compare animal models to human models when starting the SR-LAB Startle Response System for animals. The SR-HLAB is available in two different models: the SR-HLAB EMG system and the SR-HLAB PEC system. The SR-HLAB EMG system employs electrodes to capture the eyeblink response. The amplifier includes both positive (+) and negative (-) electrode inputs, multiple selectable noise band filters with over 100dB common mode rejection at 50Hz for export. Discrete, selectable amplification levels are available with 50 microvolt full scale sensitivity.

The SR-HLAB PEC system uses photoelectric cells to capture the eyeblink response. Lid closure reflects an LED ray back to an adjacent photoelectric cell; millivolt output increases with blink initiation, decreases with blink completion and a waveform is produced. Subject isolation is designed to meet ANSI/AAMI standards.
