Trust your clinical research to the system designed by the makers of the world’s most widely used animal startle system.
SR-HLAB EMG model precisely captures your subject’s eyeblink response and charts it on a wave form for your review. The system is portable and runs any startle paradigm you choose—allowing you to validate animal tests you’ve run previously with the SR-LAB.

Paired with menu-driven software that sets up in minutes with no programming required, the SR-HLAB system offers flexibility, at-a-glance chart views of your results, and data stored in a single file for easy retrieval.

Description

From the makers of the world’s most widely used animal startle system is SR-HLAB Human Startle System, designed for your human clinical research.

The SR-HLAB startle system is completely portable and can be easily set up and run from your laptop. Since the system allows you to test any startle paradigm, you can potentially validate animal models you’ve previously tested using the SR-LAB startle response system.

Set up your test sessions quickly and easily using menu driven software—and save your session definitions for later use, ensuring consistency.  The SR-HLAB is commonly used in the investigation of the pharmacology and physiology of schizophrenia, drug dependency, post traumatic stress and other disorders.

The basic system includes an integrated impedance meter (checks all electrode pairs at the same time), integrated control circuit with external connector to control 12 V devices, an auditory stimulus module (white noise, 1 KHz or 1.2 KHz) and a response module of the appropriate type for the sensor being used; EMG or PEC.

The SR-HLAB EMG model employs electrodes placed on the orbicularis oculi muscle to capture your subject’s eyeblink response.  When the muscle contracts and relaxes, a wave form of data points is created for your review.

Keep Noise Stimuli at Safe Levels

The SR-HLAB has protection circuitry that assures noise stimulus levels cannot be set at an unsafe level.  In addition, for electrical safety, subject isolation is designed to meet ANSI/AAMI standards.

One Software Program for All Paradigms

With the SR-HLAB software, you can develop and execute any startle reflex testing paradigm. Other systems utilize different software for each paradigm which has two drawbacks: One—you will spend more money, and two—you have no flexibility in designing your own paradigms, and instead, are limited to what is offered by the manufacturer.

Be assured all trials are executed without missing any using SR-HLAB’s concept of a Session containing Trials (discrete tests). Each session will run your subjects through all the trials, and save all trial data for later analysis.

Other highlights of SR-HLAB™’s software include:

  • Construct Trials Definitions with No Programming Required

Define your trials to meet your specific needs by selecting commands from a wide range within a predefined menu and then entering your start/stop times.

  • Point and Click to Set Session Level Parameters

Set your session level parameters, construct trial lists, and set up Inter-Trial Intervals using SR-HLAB’s simple point-and-click interface.

Your session parameters can include a number of samples, sample rate, background noise level, and repetitions. You can also define and edit sessions with the click of a mouse by inserting or removing Trials. In addition, edit or rename your sessions any time with ease.

The ability to automatically randomize durations for Inter Trial Intervals assures that the animal will not discern a pattern that would skew results.

  • At-a-Glance Test Monitoring

Monitor your test process at a glance by viewing response waveforms. Unlike other systems, the waveform visual gives you quick assurance that the calculated numbers are accurate.

  • Verify Data with Ease Using Data Reduction

Verify all of your startle response data with the Data Reduction post session data analysis tool. Data Reduction helps you verify data accuracy by working off scoring parameters set by you. For each response, you can review the complete waveform to verify your numeric data. Scoring parameter criterion you can set include Baseline, Onset Window Start, End Analysis and Onset. View Wave also assures your calculated values are correct by allowing you to see, export, and use your raw data values.

  • Make Data Analysis Easy with Point-and-Click Consolidation

Combine all of your data with a quick point-and-click in into ASCII file format or another statistical program. SR-HLAB Software will preview the data for you, then take it from there. Once you’ve combined your data, you can export to Microsoft® Excel at any time.
