32-Channel EEG Brain Electrical Mapping System | Brain Activity Map Recording and Analysis
The 32-channel EEG brain mapping system is an advanced digital electroencephalography device designed for comprehensive brain activity monitoring and neurological diagnosis. It acquires EEG signals via electrodes, and performs integrated amplification, analog-to-digital conversion, automatic computer analysis, and FFT processing to generate brain electrical activity maps (BEAM) with visual representation of colored power distribution.
With 32-channel EEG recording capability, high signal quality, low-noise performance, and professional analysis software, the system is suitable for hospitals, neurology departments, and diagnostic centers to evaluate neurological disorders including epilepsy, intracranial infections, cerebrovascular diseases, and brain tumors.
