The SR-LAB? Startle Response System (shock reflex system) is the world's most widely used and most successful shock and fear reinforced pre-pulse inhibition of the startle reflex test measurement system. Offers a variety of shock measuring combinations can form a complete hardware and software systems. The system can simultaneously control up to 16 test cases. Intuitive and powerful software testing capabilities to meet the non-professional user training needs. Operating under the Windows operating system. Software features flexible and easy to use. Select the following conditions and can be flexibly combined pure tone, noise, light, gas, electricity, touch and ground vibration. Flexible data organization and management software to configure multiple test stations, you can quickly test large amounts of data. Importantly, the system test mode, without expensive add-on packages or other software The SR-LAB? Startle Response System (shock reflex system) is a component of the measured shock for animals audio. It is to be monitored by a hardware and a software packages, to allow subsequent design, to collect, store and view data object of study the reaction. Variety of experimental designs, such as air stimulation, electrical stimulation (finger stimulation) and so on. Stimulus may be present in a temporary location (first or second test stimulation phase). Stimuli are allowed to include any noise or pure tone for the front pulse or shock stimulation, or both. Training also can occur without stimulation experiments. Pure tone, the user can set the duration, amplitude and frequency. The noise, the user can only set the time and amplitude. The system provides an application that allows users to change parameters measurement system for each module, and connect test hardware and objects before starting the experiment. More animal experiments, in addition to the computer automatically calibration, equipped with standard and level sensor calibrator calibrator. Here startle EMG channel integrated testing and photoelectric stimulation channels in all software modules. A high degree of sensitivity, defined and documented the offset value set in the filtered ECG software, is entered into the application module.
