Design, Characterization, and In Vivo Application of Multi-Conductive Layer Organic Electrocorticography Probes.

Biocompatible and plastic neural interface devices allow for minimally invasive recording of brain activity. Increasing electrode density in such devices is essential for high-resolution neural recordings. Superimposing conductive leads in devices can help multiply the number of recording sites while keeping probes width small and suitable for implantation.
