SR-HLAB™ PEC

Perform your startle research using the system designed by the scientists behind the SR-LAB.

SR-HLAB PEC model captures your eyeblink response data with precision and displays it in easy-to-read wave form for your review. Portable and easy to use, the SR-HLAB PEC model runs any startle paradigm you choose—and allows you to validate animal tests previously run with the SR-LAB.

Set up your software with a simple menu within minutes—and take advantage of SR-HLAB’s flexibility, at-a-glance chart views of your results, and data stored in a single file for easy retrieval.

Features#

  • Transport the system anywhere you can use a laptop
  • Digital I/O module to allow three digital output lines
  • Save session definitions for ease of use and consistency in later testing
  • Ensure noise stimuli remain at safe levels
  • Choose from white noise, 1KHz or 1.2KHz of pure tone stimulus
  • Control your scoring parameters to reanalyze response data
  • Add optional components to measure heart rate and/or Galvanic Skin Resistance
  • Pair a second computer showing images synced to the SR-HLAB Trials

Description#

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

Set up your SR-HLAB system virtually anywhere and run it from your laptop. Validate animal models you’ve previously tested using the SR-LAB startle response system since the SR-HLAB provides the ability to use almost any startle paradigm.

Using easy menu-driven software, set up your test sessions quickly and easily—and ensure consistency by saving your session definitions for later use. 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.

Keep Noise Stimuli at Safe Levels

Assure your noise stimuli cannot be set at unsafe levels thanks to SR-HLAB’s protection circuitry. 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 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 of 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 “View Wave™”

Verify all of your startle response data with the View Wave™ post session data analysis tool. View Wave™” 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.
