An Absorbable ECOG system Compatible to MRI.

We introduce our innovative HF-2 technology that integrates intracranial recordings with magnetic resonance imaging (MRI) for preclinical research. This system enhances our capabilities to simultaneously record signals from electrocortical (ECoG) called Polymer Thick Film Organic Substrate (PTFOS) [1, 2] electrodes, alongside acquiring functional MRI (fMRI) data in animal subjects. Such concurrent ECoG and fMRI recordings offer an unmatched perspective on the comprehensive network activities across cortical areas in animal models, thereby deepening our understanding of neural organization. Simultaneous ECoG/depth/fMRI is particularly transformative, providing insights into functional connectivity and oscillatory properties at both high temporal and spatial resolutions [3]. This multimodal approach is crucial for advancing research in numerous areas of neuroscience and medicine, offering detailed insights into the brain’s functional architecture.
