At CREmedical, we invent new technologies that help understand the brain, and diagnose and treat brain disorders. We are the pioneer of tripolar concentric ring electrodes (TCREs), which offer a radical improvement over the existing electrode configurations. Our TCRE based electroencephalography (tEEG) sets a new standard for physiological sensing and brain-computer-interface. Our TCRE based transcranial focal electrical stimulation (TFS) provides a new paradigm for neuromodulation.
