Please call For more information regarding this device
The Q21 is a 19+1 channel Electroencephalogram with a low noise floor of 0.25 μV peak to peak from 0.1 to 10.0Hz, meaning that you can record EEG without worrying about noise contamination. On top of our low-noise design, the Q20 is a non-multiplexed, multi-channel readout amp, minimizing slew for the most accurate whole brain imaging, and giving you the exact readout of your recordings, no loss of data or smoothing.
In NeuroField64 you can acquire stand-alone EEG or use our synchronized EEG and stimulation (pEMF, tACS, or both) Z-score training to take things to the next level. Combining Z-score with EEG allows you to target your neurofeedback protocols with an unprecedented level of accuracy, taking your therapy plans to a new level of effectiveness.
The Q21 is also fully integrated into the Neuroguide suite as well.
