Neurotechnology (or "neurotech") includes a variety of devices used to monitor or modulate the function of the nervous system. We will be focusing on noninvasive neurotechnology (which can be used without neurosurgery), and more specifically on noninvasive neurotech that is priced at a consumer level (or should be in the near future).

Several important noninvasive neurotechnologies capable of monitoring the nervous system include EEG (electroencephalography), MEG (magnetoencephalography), fMRI (functional magnetic resonance imaging), and fNIRS (functional near-infrared spectroscopy). Most affordable among these are EEG systems, which are the focus of this page. The two tables below list EEG hardware and software systems, which are generally made by different companies. Both expensive, research- and medicine-grade and cheaper, consumer-grade systems are listed. Although we have tried to be comprehensive in our list (and to contact individual companies for missing or ambiguous information), it is likely that the tables still contain errors as well as missing data. If you have any information to correct or add, please do not hesitate to contact us.

Later documents will focus on noninvasive neurotechnologies capable of modulating the nervous system, including TMS (transcranial magnetic stimulation), tDCS (transcranial direct current stimulation), and tPU (transcranial pulsed ultrasound). Only tDCS and tPU are likely to be affordable and safe enough for consumer use in the near future.
