I. Overview ZH-ZJT type shock reflex system for the study of animal to sudden intense stimuli and data analysis, a computer can be controlled from 1 to 5 shocked reaction tank, noise stimulation while adding light, electricity, gas stimulation according to user-defined interval given the appropriate stimulus, as well as fear-induced shock reaction time, lurking response amplitude shock will be displayed and stored for further statistical analysis of parity in the results. Data can import Excel, SPSS statistical convenience. Second, the technical parameters 1, the weight sensor selection and styling (1 ~ 2kg) 2, using the main controller + device control card mode 3, the function device control card (1) can accept commands from the host controller, acoustic, Start with a stop light, electricity, gas, (2) can collect weight sensor signal amplification, and transmitted to the master controller (3) an observation device to configure a device control card 4, the main controller functions: (1) with PC communication, accept instructions PC for data acquisition, sound and light electric start and abort (2) be able to communicate with the device control card (3) can simultaneously control four devices control card, and work independently 5, with PC software interface (1) provides a graphical interface for data acquisition, waveform display (4-channel) (2) provides acquisition parameters settings interface (3) provides real-time data acquisition (Y value) (4) sound and light start time, duration, end time is determined by the host computer (5) signal acquisition start time, duration, end time is determined by the host computer (6) provides OCX or Dll modular design. Development platform using Visual studio.net2003 6, Technical Specifications (1) sound stimulus intensity: 85 db, 95 db, maximum 130 db, can be set by software; acoustic stimulation frequency: can be set by software, 4 ~ 25KHz (2) light stimulus Strength: 2w; light stimulation frequency: can be set by software, the default 60 beats / min (3) electrical stimulation: current intensity 0 ~ 3mA (constant) adjustable (4) Gas (tactile stimulation): by adjusting the air pressure cylinders, Gas output time can be controlled through the software valve (5) sampling frequency: 0 ~ 500KHz, can be set (6) data requirements through software, communication 16 A / D digital signal (7) PC and the next crew USB interface mode (8) Data collection: Start stimulation, animal response latency, highly reactive animals, animal reaction time, collecting animal sounds decibels (9) can be flexibly configured to stimulate ways: as sound, light, electricity, combined with the shocked reflex system (The SR-LAB? Startle Response System) 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. Other features include, testing all channels A / D converter. The same pass CE and FDA CFR Part 11 standards
