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 a microSD card on the headstage in untethered (wireless) mode and can also live stream data 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, gyroscope and radio receiver
  • Optimized for high throughput and social experiments
  • Unique alignment system to make daily connecting/disconnecting easy; see video demos
  • Compatible with probes or electrodes. For a wide array of compatibility options, see adaptors and EIBs 
  • HDMI cable
  • Input testing board
