CREmedical invents new technologies that helps the research community to understand the brain, diagnose and treat brain disorders. The company is the pioneer of tripolar concentric ring electrodes (TCREs), which offers a radical improvement over the standard electrode configurations. Their tripolar EEG ( tEEG ) and the transcranial focal electrical stimulation device (TFS) are well tried methods and tools in seizure-, and biomarker- detection, as well as event related potentials (ERP) research and neuromodulation.
