The DSI-24 is a research grade wireless EEG headset designed for rapid application of 21 sensors at locations corresponding to the 10-20 International System. Its main features include:
The DSI-24's practicality, portability, and high signal quality opens the door to taking numerous applications that were previously limited to lab environments to more naturalistic settings. Such applications include:
The DSI-24's practicality, robustness to motion artifacts, high signal quality, and unsurpassed comfort beckoned for a version suitable for children.
And, thus, by popular demand, we have developed a smaller version of our DSI-24: The DSI-24-C, which is designed to comfortably and accurately position the dry sensors on heads 48-54 cms in circumference, thus fitting >90% of male children 3-7 years of age, and >90% of females 4-9 years old. (The DSI-24 optimally fits 54-62cm)
This unit is thus an excellent complement to a DSI-24, or can be purchased separately, as the child-sized version is a stand-alone unit, and includes its own integrated amplifiers, digitizers, and 19 sensors on the head at the International 10/20 System locations, as well as 2 removable earclips and 1 auxiliary input for ECG/EMG/EOG.
So please ask us about our special bundle pricing.
