Horizontal Headstage 256-Channel Datalogger (HH256)

The HH256 neural datalogger records 256 channels of broadband electrophysiological neural data for both tethered and untethered (wireless) experiments. The HH256 amplifies, digitizes and records neural data. When recording untethered, HH256 records all neural and sensor data to on-board removable microSD storage under battery powe without the need for cable tethers. When connected to the MCU via HDMI for tethered recording, data is recorded to the local computer, and can be live streamed in Trodes. HH256 records broadband electrophysiological data at sampling rates up to 30 kHz. Ideal for experiments with models such as rats, marmosets or macaques.
