Please note that the Neuro Gamma device is not the same as the Neuro RX Gamma that is currently being used in our clinical trials.
The RX Gamma is intended to be fully compliant with regulatory requirements for a medical device and will not be available without regulatory clearance. The “Neuro RX Gamma” is therefore a different product from the “Neuro Gamma”.
