Animal research biosignal acquisition system

multi-channelwith EMG

The recording and analysis of bioelectrical signals such as EEG and EMG are necessary means for neuroscience research. EEG/EMG acquisition and analysis system is an indispensable instrument for sleep disorder, cognitive disorder, epilepsy and other fields of rats and mice, which can accurately monitor and analyze EEG/EMG/acceleration/synchronous video signals of rats and mice. By monitoring animal EEG and EMG data, we can deeply study sleep patterns, seizures, learning and memory behaviors, anesthesia excitation inhibition, nerve concussion and their functions in various nervous system diseases, and provide scientific basis for the treatment of related diseases. The acquisition and analysis system of EEG/EMG has the characteristics of real-time, safety, high efficiency, stability, automatic recording and analysis, which greatly reduces the labor intensity and improves the accuracy. The system collects the EEG of animal cortex/nucleus and the EMG of neck through special screw electrode and EEG headstage. The system amplifies and filters the signal step by step through the head-mounted preamplifier and collector to minimize the signal artifacts and obtain clean data waveforms. The system supports automatic analysis and obtains various statistical data of WAKE-NREM-REM and seizures. Features Analytical gold standard, head-mounted amplifier: the EEG and EMG were recorded in an invasive way for analysis, which was highly recognized internationally; Equipped with a head-mounted preamplifier, it is light in weight and does not affect animal activities and monitoring.
