AI Technical Summary
Traditional transparent cranial windows with integrated electrodes can only record local field potential signals and cannot record neuronal action potentials. Furthermore, they cause severe optical obstruction, which affects neuronal observation and optical imaging.
A three-dimensional structure with the wire layer perpendicular to the first insulating layer and the conductive layer is adopted. Combined with the double-layer insulating encapsulation and adhesive layer design, a vertical multi-channel extracellular electrode is formed, which reduces the projection area of the opaque material in the optical imaging direction, achieves high light transmittance and high conductivity, and enables simultaneous electrophysiological recording and optical imaging.
It enables extracellular recording of deep cortical neurons, maintains high light transmittance, reduces electrode interface impedance, and ensures long-term stable photoelectric dual-modal synchronous monitoring, supporting brain-computer interface research such as neural circuit analysis and brain function localization.
