Horizontal Headstage 128 Channel with Datalogger (HH128)

The HH128 is a complete, miniaturized data-logging system for recording 128 channels of neural data wirelessly. The HH128 amplifies, digitizes and records neural data to the onboard microSD card under battery power when operating in untethered (wireless) mode, or streams data live to the MCU when connected via HDMI in tethered mode. 

  • A complete recording system in 11.1 grams; lightweight enough for freely-moving rats and larger animals
  • 128 channels of neural data plus integrated accelerometer and gyroscope
  • Optimized for high throughput and social experiments
  • Unique alignment system to make daily connecting/disconnecting easy; see video demos
  • Compatible with most probes, arrays and drives. For a wide array of compatibility options, see adaptors and EIBs 
  • HDMI cable
  • Input testing board
