Electrical impedance tomography

Introduction. There exists no method for non-invasive imaging of neural activity throughout the brain with a millisecond and millimetre resolution. EIT can theoretically achieve this by injecting a constant current with surface electrodes, measuring the voltage change associated with neural depolarization and reconstructing images of the activity. However, EIT with scalp electrodes was unsuccessful in vivo. MDEIT could improve image quality by measuring the magnetic field which is not attenuated by the skull. Aims. Image simulated neural activity in the human brain using MDEIT and EIT with sca

Neural interfaces to peripheral nerves are increasingly employed for basic research, neuroprosthetics, and bioelectronic medicine (‘electroceuticals’). We previously established a pipeline for hybrid electromagnetic-electrophysiology modeling of nerve stimulation on the o2S2PARC platform for collaborative, FAIR, and reproducible computational neurosciences. It leverages histological data to generate a detailed anatomical model of the nerve microstructure and to functionalize it with populations of fiber neuro-dynamics models (myelinated/unmyelinated, statistical distributions of fiber types an
