Electrophysiology recording system TOW‑AR4M

Product Overview
The TOW-AR4M wireless small-animal in-vivo electrophysiological recording system collects EEG, EMG, ECG and local field potential (LFP) signals with synchronized video from freely moving laboratory animals. It supports long-term and multi-animal studies in epilepsy, sleep, anesthesia, pain and neural-circuit research. The system supports cloud-based data management and an optional local real-time mode when used with the DataHub.

Product Features

• Improved experimental throughput and remote monitoring
  • Simultaneous recording from multiple animals
  • Scheduled or manual data acquisition
  • Real-time remote monitoring from PC and mobile APP
  • Replaceable battery in recording unit for continuous sessions
• Safe and data-ready design
  • Fully wireless operation eliminates cable breakage risk
  • Signal quality suitable for experimental analysis workflows
  • Cost-efficient per-animal deployment for large studies
• Reduced burden on animals
  • Compact, lightweight modules suitable for animals from 3 weeks of age
  • Unrestricted free movement without cable tangling

Product Composition
The system comprises AR4 electrophysiological recording modules, DataHub data repeater, video module, ARMrecorder PC software and ARrecorder mobile APP. Data can be managed via cloud services or locally with the DataHub.

Key Components and Functions

• Electrophysiological Recording Module (AR4)
  Acquires, transmits and stores electrophysiological data. Each AR4 records one animal. Standalone AR4 supports cloud management; pairing with DataHub enables local real-time management.
• Video Module
  Works with DataHub to stream synchronized video to PC software.
• DataHub Repeater
  Aggregates data from recording modules and forwards to PC-side software. Supports 1–8 AR4 modules per DataHub; enables local control and data management.
• PC-side Control Software (ARMrecorder)
  Manual or scheduled start/stop of recordings; real-time visualization and data export.
• Mobile APP (ARrecorder)
  Pairing, Wi‑Fi configuration for receivers, basic control and real-time signal display on mobile devices.

Applications & Cases

• Synchronized EEG–EMG–ECG acquisition
  Wireless, cage-side hardware enables large-scale long-term monitoring with synchronized video and electrophysiological traces.
• Epilepsy monitoring
  Long-term seizure detection with synchronized video for event validation.
• Sleep and sleep-deprivation studies
  Compatible with interventions under free-moving conditions while preserving circadian patterns.
• Anesthesia monitoring
  Records EEG across anesthetized and awake states without cable constraints.
• Closed-loop regulation
  API access for real-time streaming of EEG, ECG, EMG and motion data to drive external stimulators.
• Local field-potential acquisition
  Deep-brain electrode recording for neural-circuit studies.
• Multi-animal parallel recording
  Synchronized acquisition and playback across multiple freely moving animals using combined electrophysiology and video modules.
