Medical Event-Related Potential System
PZ-ERP is a medical event-related potential system developed by Puzhuo Medical for cognitive function assessment and neuroelectrophysiological examination. The system collects the lock-in electrical activity generated by the brain in response to specific stimulation events through scalp electrodes, and extracts microvolt level evoked potentials from the background EEG through multiple stacking averages, providing objective electrophysiological indicators with millisecond level time resolution for cognitive processing processes such as perception, attention, memory, and language. The system adopts a 34 channel EEG integrated amplifier, supports full frequency DC sampling, with a sampling rate of ≥ 4kHz, A/D conversion of 24 bits, input impedance>1GHz, input noise<1>100dB, ensuring signal purity from the acquisition end; Equipped with 8-bit TTL signal input and TCP/IP protocol dual synchronization channels, it can work in conjunction with mainstream stimulation presentation software such as E-Prime, Presentation, PsychoToolbox, PsychoPy, and transcranial magnetic stimulators of the same brand; The supporting collection and analysis software integrates real-time online analysis, one click automatic ERP processing, and multi-dimensional visualization, covering the complete workflow from data collection, artifact removal, component extraction to report output.
